Postmortems with Heat-Specific Learnings for Summer Festivals

Learn how festival organisers turn summer heatwave challenges into next-year wins with rapid postmortems, all-stakeholder feedback, and ‘we heard you’ changes.

Introduction: From Heatwaves to Lessons Learned

Summer festivals are magical, but they can also be merciless when the heat soars. In recent years, extreme temperatures at open-air events have tested even seasoned festival teams. For example, on a sweltering day at Boston Calling 2024, attendees faced overcrowding and water shortages, with some collapsing from dehydration (www.axios.com). And who can forget how Woodstock ’99 turned chaotic, in part due to 104°F (40°C) heat and outrageously overpriced water (coconote.app)? Stories like these underline a critical truth: a festival’s success isn’t just about during the event – it’s also about what happens after the event. This is where a thorough postmortem comes in.

Experienced festival organisers know that the hours and days immediately following a festival are prime time for learning. Emotions, triumphs, and mishaps are fresh in everyone’s minds, making it the perfect moment to capture insights that can protect and improve future events (medium.com). This article dives into how today’s top festival producers conduct post-festival postmortems with a special focus on heat-specific learnings. From rapid feedback collection and actionable improvement plans to community transparency and long-term planning, we’ll explore how to turn a scorching challenge into next year’s success story.

Debrief Within 72 Hours: Why Speed Matters

Time is of the essence once the last encore has finished. Within 72 hours of your festival ending – ideally even sooner – you should initiate a postmortem debrief. Why the rush? Because memories fade fast and small details that could spark big improvements might slip away if you wait too long. Industry best practices suggest scheduling a wrap-up meeting as soon as possible, often even before the festival begins (medium.com). Many large festivals plan a staff debrief on the next weekday after a weekend event, ensuring that key staff, crew leads, and partners can download their thoughts while the experience is still fresh.

In these debrief meetings, create a safe, constructive space for honesty. Encourage everyone to speak up about what went wrong and what went right, especially regarding heat-related issues. For example, were there specific times of day when crew felt overwhelmed by the sun? Did any equipment (like scanners or sound systems) falter due to high temperatures? By having a quick turnaround, you catch these observations in vivid detail rather than foggy recollections. A speedy postmortem also signals to your team and stakeholders that continuous improvement is a core value – you’re not dwelling on mistakes, you’re actively mining them for solutions.

Gathering a 360° View: Crew, Vendors, Medical & Guests

A festival is an ecosystem. To truly understand what happened during a hot festival, gather feedback from all corners of that ecosystem. Each group – crew, vendors, medical staff, and attendees – has unique insights:

  • Festival Crew & Staff: Your production crew, security, stage managers, and volunteers witness operations up-close. Within 72 hours, have department heads collect input from their teams. Did security notice more incidents of fainting near Stage 2? Were volunteers sufficiently rotated to avoid heat exhaustion, or did some end up pulling long shifts under the sun? Crew feedback often highlights operational stress points. For instance, the production team might report that generators overheated in the 3 PM glare, suggesting you may need to invest in heat-resistant equipment or shading for critical gear next year.

  • Vendors & Concessionaires: Reach out to food and beverage vendors, merchandise stalls, and suppliers soon after the festival. They can tell you if the event’s conditions impacted their service. Maybe several food vendors ran out of ice or had refrigeration issues due to the 35°C heat. Perhaps queue management at drink stations broke down when thirsty crowds surged. Vendors are also stakeholders in attendee satisfaction – a drinks vendor can report if they saw unusually long lines for water or if their staff struggled in the heat. Capturing their perspective (via a quick survey or phone call) not only uncovers problems you might miss but also builds goodwill. It shows you consider them partners in the festival’s success, not just contractors.

  • Medical and Safety Teams: Your on-site medical crew’s input is crucial after a heat-heavy event. Request a short report within a day or two detailing the number and nature of health incidents. Patterns in medical data are goldmines for safety planning. Did the first aid tents treat dozens of dehydration and heatstroke cases? (At Glastonbury 2019, for example, the on-site ambulance team handled 27 heat-related calls as temperatures hit 30°C (www.theguardian.com).) What times of day saw the most cases, and where? The medical team might say, “We saw a spike of heat exhaustion around 2–4 PM primarily near the main stage, indicating not enough shade or water there.” Such insight directly informs where to add shade canopies or extra water stations. Likewise, safety personnel (security and crowd management) can report if any evacuation or cooling procedures were triggered. Every detail from the medical logs – down to how many IV bags of fluid were used – can justify budget for more water, misting fans, or medics next year.

  • Attendees (Guests): Last but never least, gather the voices of your audience. Attendee feedback will often confirm and contextualize the operational observations from staff. Within 24–48 hours post-event, send a post-festival survey to ticket buyers (your ticketing platform, like Ticket Fairy, can facilitate a quick blast to all attendees). Keep it concise but targeted: ask about their experience with water availability, shade/ cooling zones, and any health or safety concerns. Include a mix of ratings (e.g., “Water refill availability: 1–5”) and an open comment for “How did the heat affect your experience, and what could we do better?” The sooner this goes out, the higher the response rate and the more candid the answers – festival-goers are more likely to share vivid memories of waiting in a water line for 30 minutes while it’s fresh in their mind. Also monitor social media and community forums in those first days. After Download Festival 2023 in the UK, for instance, social media buzzed with complaints about a lack of shaded areas during a heatwave (www.edinburghnews.scotsman.com). By capturing those public comments, you not only get unfiltered insight but can also respond to let attendees know you’re listening.

Pro Tip: When collecting feedback, meet people where they are. Crew might prefer a quick in-person debrief or a simple shared document to jot notes. Vendors could respond well to an email or Google Form. Attendees will respond if it’s easy – one-click survey links, social media polls, etc. And don’t forget your local community (residents and authorities). For summer festivals in particular, local officials or neighbours might have feedback about issues like noise or traffic exacerbated by daytime heat (e.g., more people left the site at peak heat, causing unusual traffic at 3 PM). Fold their input into your postmortem to cover all bases.

Heat-Specific Issues: Identify and Quantify Them

When the sun turns up the heat, it creates a cascade of challenges that wouldn’t appear on a cooler day. A thorough postmortem for a summer festival needs to identify every heat-related issue and, where possible, attach a number to it. This is where you turn anecdotes into data – and data into action.

Start by reviewing hard data from the event:
Medical records: We’ve mentioned counting medical incidents, but go deeper. What percentage of total medical cases were due to heat (dehydration, heat exhaustion, sunburns)? Was this higher than expected for the event size? For example, if 50 out of 200 total medical calls were heat-related, that’s 25%. If your plan was for 10%, you’ve clearly underestimated the heat risk. Also, look at time stamps: if a spike in incidents occurred when temperatures peaked at 4 PM, that’s a flag. In one case, a festival in Mexico noted that most dehydration cases happened in late afternoon when the crowd was densest at the main stage – a clue that people were reluctant to leave a good spot for water. Armed with such info, you can target interventions (like distributing water to front-of-stage crowds or scheduling artists with calmer sets at peak heat to encourage rest).

  • Water consumption and supply: Examine how much water was distributed or sold. If you provided free water refill stations, check how many liters or tank refills were used per day. Did you run out of water at any point or come close? Long queues at water points are a metric too – if refilling a bottle took 20 minutes at midday, that’s quantifiable (and unacceptable in heat). We heard about festivals where demand outpaced supply, such as Glastonbury 2019 where taps saw long queues once the mercury climbed (www.theguardian.com) (www.theguardian.com). If possible, use staff observations or even video footage to estimate wait times at peak. If vendors sold bottled water, analyze sales numbers – a spike in water sales could mean folks were desperate for hydration (or conversely, if sales dropped, maybe people couldn’t reach vendors easily in crowds).

  • Infrastructure strain: Heat can strain equipment and infrastructure. Note any power outages or tech failures that coincided with high temperatures. Did the refrigeration in the medical tent struggle to keep IV fluids cool? Did any ticketing or scanning equipment have trouble (devices can overheat in direct sun)? If your entry scanners or wifi went down in the afternoon, that might correlate with 40°C heat on the tech. Quantify the downtime or number of affected devices. Modern festivals often use RFID wristbands or app-based ticket scanning – check logs for any slowdowns in scan rates during the hottest hours. This could indicate technology literally melting or staff slowing down, which again points to solutions (like providing shade umbrellas at gates or backup battery-operated fans for equipment).

  • Attendance patterns: Look at the crowd flow relative to temperature. Did many attendees retreat to shaded areas or leave the festival grounds during peak heat? If you have entry/exit scan data or even estimates from security, plot the crowd size over the day. A drop in attendance on the field at 2 PM followed by a surge after 5 PM (when it cooled) might indicate people escaping the heat. That’s a metric to note – e.g., “20% of attendees left the main stage area between 2-4 PM due to heat.” If you had programming during that time, those acts might have been impacted by smaller crowds, and you’ll need to revisit scheduling or shade provisions.

Once you’ve gathered these data points, tie them to specific heat-related causes. This is the detective work of the postmortem: was it heat that caused a particular problem or something else? For instance, if 30 people reported feeling faint, determine how many were directly due to heat versus other factors like alcohol. (Often it’s both – heat + dehydration + alcohol is a dangerous mix. Medical experts note that festival-goers consuming alcohol or drugs are at much higher risk of heat illness (uk.style.yahoo.com).) Understanding the root cause lets you propose the right fixes.

From Findings to Action: Tie Actions to Metrics and Owners

Raw feedback and data are only as good as the actions you take from them. After identifying what went wrong (and right), the next step is to define concrete actions to address each issue – and assign those actions to specific owners on your team, along with measurable targets.

Start by listing every significant finding from your 360° feedback and data analysis. For example, you might have:
– “Not enough shade in main stage area – attendees left midpoint or got sick.”
– “Water refill stations overwhelmed during peak afternoon – 20 min average wait.”
– “Crew rotation insufficient – 5 security staff treated for heat exhaustion.”
– “Ice supply for vendors ran out twice.”
– “Attendee feedback: 30% rated water access poor.”

Now, turn each finding into an action item. The key here is to make them SMART: Specific, Measurable, Achievable, Relevant, and Time-bound. And crucially, assign an owner (a person or department responsible) to each. Some examples:

  • Shade Expansion: “Increase shade at main stage by 50% (from 200 sqm to 300 sqm coverage) by next year. Owner: Operations Director. Metric: Shade coverage area; target no more than 5% of attendees reporting ‘too little shade’ in next year’s survey.” This ties the solution (more shaded space, perhaps via tents or structures) to a metric (attendee satisfaction or just square meter of shade per 1,000 attendees). It’s actionable and someone is clearly accountable.

  • Water Access Improvement: “Double the number of water refill stations from 10 to 20 and add 2 misting/cooling stations by the 202X festival. Owner: Logistics Manager. Metrics: Maximum water queue time under 5 minutes; water consumption capacity increased to 1.5 liters per person/day.” These metrics might come from standards or your own event history. If this year each person effectively could get 1 liter in the heat, bumping to 1.5 or 2 liters could be the goal. You might also set a target like “0 heatstroke hospitalizations” or “halve the number of dehydration medical calls.” Ambitious, but setting the intention drives everyone to aim for it. For instance, after a particularly hot year, Bonnaroo Festival in Tennessee committed to dramatically expanding free water access, and they saw heat incidents decline the following year – tying cause and effect.

  • Crew Welfare Protocol: “Implement mandatory crew break schedules and provide cooling vests or rest tents for staff. Owner: Crew Manager / HR. Metric: 0 cases of staff heat exhaustion; 100% compliance with break schedule logged each day.” It’s important not to overlook your staff and volunteers – happy, healthy crew will keep attendees safe too. If five security guards went down this year, that’s unacceptable and easy to prevent with better planning. Owners for these actions might also include third parties – e.g., if an outside security contractor understaffed breaks, coordinate with them to ensure it doesn’t recur.

  • Vendor Support: “Add an ice truck on standby for vendors and double the cold storage capacity. Owner: Vendor Coordinator. Metric: No mid-event ice shortages; vendor satisfaction survey average 4/5 on ‘operational support.’” The idea is to anticipate their needs. If several vendors reported issues, you might also include them in future planning meetings or ask for their input on solutions now.

  • Education/Communication: Not every fix is physical infrastructure – some are about informing attendees better. If you found that many attendees didn’t utilize the free water because they weren’t aware of all the station locations (it happens!), an action could be “Improve festival map and signage for water and cooling stations; push heat safety tips via app notifications during event. Owner: Marketing/Communications. Metric: 90% of survey respondents were aware of water refill stations (up from X% this year).” Technology can help here: some festivals send push notifications like “Remember to hydrate – free water refill at all main areas!” when temps pass a threshold.

Once actions and owners are defined, document them in a postmortem report. It doesn’t have to be fancy; even a shared spreadsheet or slide deck can work as long as it’s accessible and clear. The critical part is that each action is tied to a metric – something you can check next year to know if it worked – and someone who will champion it. When you reconvene for pre-production meetings for the next festival, these action items should be on the agenda, essentially forming a “to-do” list derived directly from this year’s lessons.

“We Heard, We Changed”: Closing the Feedback Loop with the Community

Festival-goers love to know they’re listened to. After all, they’re the reason the event exists. Sharing back with your community the improvements you’re making based on their feedback not only builds loyalty and trust, it also sets expectations that next year will be even better. A great framework for this communication is the “You said, we did” approach (or as we call it, “We heard, we changed”).

Here’s how you can implement it:
Compile Key Feedback Themes: After analyzing surveys and comments, pick out the top concerns or suggestions attendees (and crew) raised. Be honest with yourself here – even if it’s uncomfortable. Did hundreds of people say there weren’t enough water points? Was there a recurring complaint about lack of shade, or perhaps about something like “the ground was too dusty” (which can be worse in heat when grass dies off)? Identify the handful of issues that really stood out.

  • Announce Your Improvement Plan: Use your festival’s official channels (email newsletter, blog, social media) to publish a postmortem summary for the public. Thank everyone for coming and for sharing feedback. Then explicitly list the “We heard you on X, so we’re doing Y” items. For example:
  • You told us the sun and heat were brutal and there weren’t enough shaded areas – We’re adding three new shade structures (over 500 square meters of shade) around the main field for next year.
  • We heard that water refill lines were too long at peak times – We’re doubling the number of free water stations and will have roaming water vendors in crowd areas.
  • You said the medical tents were hard to find – We’re improving signage and adding a visible first-aid flag at each medical station.

This transparent approach was used by Firefly Music Festival a few years back – they openly shared how attendee feedback led them to improve exit traffic flow and add free water points, which in turn earned praise from the community for being responsive. By highlighting changes, you not only inform past attendees, but you also market the improvements to future attendees.

  • Tone and Timing: Aim to share this update once you have your major changes confirmed – perhaps a month or two after the festival (or whenever tickets for next year might go on sale). Earlier if possible, while the memory is still fresh, is better – it shows you’re on it. Keep the tone positive, appreciative, and forward-looking. Even if there were serious issues, frame the narrative around solutions. For example: “The heat wave during FestName 2025 was a huge challenge. We’ve reflected on all your feedback and our team has been hard at work planning big improvements for FestName 2026 to keep everyone cool and safe.”

  • Community Engagement: Don’t make it one-way; invite further thoughts. Perhaps end your update with, “Let us know what you think of these changes, or if we missed anything.” This can lead to a constructive dialogue and shows humility – you’re willing to keep learning. Some festivals hold public forums or live Q&A chats online post-event for fans to ask questions of organisers directly. If your audience size and resources allow, this can be a powerful way to humanise the organisation and build trust. Just be sure to have clear answers ready for the tough questions (like “Why did this fail in the first place?”) by focusing on how you’re ensuring it won’t happen again.

  • Follow Through: After announcing “we will change X,” make sure you do it. Nothing will erode credibility faster than promising improvements and not delivering. This is why tying changes to next year’s planning (our next section) is vital – it ensures these promises are baked into the festival’s DNA moving forward. When next year’s festival comes around, you can even put out reminders like, “It’s going to be hot this weekend, but don’t worry – we took your feedback and doubled our water stations and added misting cool-down tents. We’ve got you covered!”

The pay-off to this community transparency is huge. Fans feel a sense of ownership in the event’s evolution. They’re more likely to give constructive feedback if they know you listen. Plus, when things improve, they’ll appreciate it consciously – “Wow, the water lines are shorter this year!” – which boosts their overall satisfaction. In an age where festival-goers often share their experiences online, being known as a festival that listens and adapts is a competitive advantage.

Bake Lessons into Next Year’s Planning (RFPs, Budgets & Beyond)

The final step in turning your postmortem insights into real-world improvements is to institutionalize those changes for next year. It’s one thing to say “we’ll have more shade and water” and another to actually budget for it, contract it, and implement it on-site when the time comes. This is where you take those action items with owners and ensure they are written into the festival’s roadmap – from RFPs to site plans to staff training.

  • Budgeting: Money talks. If your plans require additional spending (and many will – extra tents, more water infrastructure, extra staff, etc.), start working on the budget implications early. Allocate funds specifically for these heat-mitigation measures. It might mean shifting budget from elsewhere or finding new sponsorship (perhaps a sports drink or water company would sponsor the new hydration stations?). The key is not to treat these items as optional. For example, if your postmortem concluded “add 5 large shade tents, cost $50,000,” that line needs to appear in the draft budget for next year from the get-go. This prevents the all-too-common issue of safety improvements being value-engineered out when money gets tight. Remember Woodstock ’99’s lesson – they tried to cut costs on safety, water, and infrastructure (coconote.app) (coconote.app), and it ended in disaster. Commit to the investment in attendee welfare; it pays off by avoiding bigger problems (and potential lawsuits or reputation damage) later.

  • RFPs and Contracts: Many festivals work with third-party vendors for crucial services (security firms, medical providers, tent suppliers, etc.). When you draft Requests for Proposal (RFPs) for these services or renegotiate contracts, explicitly include your new requirements. If the medical team needed more staff or equipment on standby for heat emergencies, ensure the medical services RFP for next year specifies a higher personnel count or extra ambulances during daytime. If shade structures were lacking, include in your site production RFP a requirement for those additional tents or canopies. If you’re contracting a water supplier (some festivals truck in drinking water or have refill infrastructure providers), double the volume or number of refill stations in that contract. By baking changes into legal agreements, you make them concrete. It also signals to vendors that you’re serious about addressing past issues. For instance, a festival in Australia added a clause in their staging company’s contract post-2018: the company had to provide heat-resistant stage flooring after regular turf got so hot it burned some people’s feet in the mosh pit. This kind of specific change can emerge from postmortem insights (“fans complained the floor was too hot to stand on by afternoon”).

  • Timeline and Production Schedule: Incorporate changes into your planning timeline. If you know you’ll be adding water stations, schedule their installation and testing well in advance of gates opening. If you plan to use a new shade structure type, perhaps arrange a site visit or demo during the off-season to ensure it’s effective. Essentially, treat these improvements as must-do milestones, not last-minute add-ons. Many experienced festival producers create a “master action list” for the year, based on the previous event’s postmortem. This list is reviewed at each planning meeting. For example, six months out: “Confirm additional shade tents ordered – Owner: Ops Director – Status: done/pending.” Three months out: “Update site map to include misting stations – Owner: Site Planner – Status: done.” This keeps everyone accountable and the improvements on track.

  • Training and Protocols: If the postmortem identified procedural issues (say, communication breakdown when dealing with heat-struck attendees, or staff not knowing how to use a fire hose for cooling), then update your training programs and manuals. Next year’s volunteer orientation should include a segment on spotting and responding to heat illness, if it was lacking. The security briefing might incorporate, “If temperature exceeds X, here’s the procedure for rotating staff and announcing to crowd to hydrate.” These protocols might also go into an updated risk management plan – a formal document festivals often have. Summer festivals should definitely have an extreme heat section in their emergency plans, much like they have for thunderstorms or other risks. Use what you learned this year to beef up that section. For instance, if one of your metrics was the Wet Bulb Globe Temperature (WBGT) reading (used to measure heat stress) and you realized you need to act when WBGT hits a certain number, put that threshold and action steps into the playbook.

  • Site and Venue Adjustments: If your festival is at a fixed venue or re-used site each year, explore any physical changes that could help with heat. Maybe planting trees isn’t feasible for next year, but could it be a 3-year plan? Some events have installed permanent shade sails or built misting “cool zones” that became regular features. If you run a multi-day event, consider how nighttime can be used to recover (e.g., spraying down dusty grounds or refilling water reserves each night). Work with the venue or landowner on these if needed. All of these ideas should trace back to the postmortem – each one solving a problem that was identified.

In essence, what you’re doing is embedding the lessons learned into the DNA of next year’s festival. By making them part of official documents – budgets, contracts, schedules, manuals – you guard against the risk of forgetting or ignoring those lessons as time passes. It’s a bit like leaving yourself a time capsule of wisdom that will open when planning kicks off.

Scaling Your Postmortem: From Niche Events to Mega-Festivals

Every festival is different. A boutique indie music weekend for 2,000 people in a local park won’t have the same postmortem process as a 100,000-strong international festival spanning a week. But the principles we’ve discussed scale up and down – they just need the right approach for the festival’s size and type.

For small or local festivals: You might not have formal “departments” or tons of data, but you have the advantage of a tight-knit team and community. Leverage that intimacy. Perhaps you can gather all staff and even a few key volunteers in a single room the day after the event for a frank talk. It could be as informal as a BBQ debrief where everyone shares one thing that could improve (just be sure someone is taking notes!). For attendee feedback, you might personally email or call some regular attendees or community members for input – qualitative insights can be as valuable as survey stats when numbers are small. Also, in smaller events, word-of-mouth in the community is huge. Show them you care: for instance, a small town summer festival in France might publish a short thank-you and “what we’ll do next year” note in the local paper or Facebook group. Since budgets are tighter, prioritise the most critical heat-related fixes first (if you can’t afford 10 tents, get 2 big ones, etc., and maybe ask the community or sponsors to help fund specific improvements).

For large-scale festivals: Complexity is higher, so organization is key. Break down the postmortem process by department. The operations team can handle infrastructure issues, the guest services team can compile attendee survey data, the medical team provides their report, and so on. You might end up with a comprehensive report that runs dozens of pages – that’s fine, as long as it’s digestible by section. Large festivals also often involve external stakeholders in debriefs: city officials, emergency services, venue owners, etc. Expect to have a formal debrief meeting with authorities especially if there were notable incidents (in some countries this is required). Come prepared with your data and the steps you intend to take; this can go a long way in securing permits for next year. For example, after the hot 2024 Boston Calling where the mayor expressed concern (www.axios.com), the organisers would likely meet city officials to assure them of capacity and safety improvements. A mega-festival might also use advanced tools – data analytics on feedback, heat mapping of the site to plan new shade, or consulting with meteorologists and health experts for next year.

Different festival genres & audiences: Postmortems should also consider the type of event and who attends. A dance music festival where young adults party non-stop may have more issues with dehydration (and substances), so the learnings might focus on around-the-clock free water, 24/7 medical, and “chill-out” zones for people to cool off. An all-ages family festival might find that kids and elderly attendees needed more cooling areas – maybe next year they’ll add a family cooling tent with fans and water sprinklers for kids to play in. A food & wine festival might discover that heat affects food safety and wine storage, so their actions could involve more cold storage and shaded tasting areas (nobody wants a warm white wine in 35°C sun!). Cultural festivals or city events might have more community involvement; their postmortems might involve town halls with residents, as heat can also impact locals (imagine a neighbourhood complaining that festival-goers crowded their public water fountain because the event’s water ran out!). Tailor your feedback loop to these nuances.

No matter the type or scale, the core idea is the same: listen, learn, act, and communicate. Heat waves and other summer challenges do not discriminate by festival size – everyone must adapt. In 2022, even a relatively small open-air theatre festival in Canada had to pause shows due to heat extremes, while giant events like Lollapalooza and Glastonbury have built reputations for dealing with weather ups and downs, precisely because they evolved through years of lessons.

Conclusion: Turning Up the Heat on Continuous Improvement

A great festival organiser sees each event not just as an endpoint but as a stepping stone to an even better one next year. Postmortems are the bridge that carries you there. Especially in the era of climate change, where a sunny day can turn into a dangerous heatwave, the ability to learn and adapt is as important as booking the right headline act. By gathering insights from crew, vendors, medics, and guests while the festival “heat” is still fresh, you capture the full picture of what happened. By tying every promise to a metric and an owner, you ensure accountability and measurable progress. By closing the loop with your community, you turn critics into supporters and ticket buyers into partners. And by baking those changes into the very fabric of next year’s plans, you don’t just promise improvement – you budget and build for it.

At the heart of it, festival production is a labour of love. It’s about creating unforgettable experiences and doing everything possible to keep people safe while they make memories. Every misstep or challenge – even getting scorched by the sun – is an opportunity to learn. The most legendary festivals in the world, from Glastonbury to Coachella to regional gems like Fuji Rock in Japan or Splendour in the Grass in Australia, all got where they are through constant evolution. They try new things, they learn from mistakes, and they never rest on their laurels.

As our veteran festival producer would advise: “Embrace the post-festival postmortem. It’s your best friend in making sure next summer’s festival blows this year’s out of the water – keeping fans happier, safer, and eager to come back for more.” With thorough heat-specific learnings and a commitment to action, your festival will not just survive the summer sun, but thrive under it, year after year.


Key Takeaways

  • Debrief quickly and broadly: Hold postmortem meetings within 72 hours of your festival, involving all key groups – festival staff, vendors, medical teams, and attendees (via surveys) – to capture fresh insights (medium.com).
  • Focus on heat-related data: For summer events, pinpoint heat-caused issues (e.g., number of dehydration cases, water station wait times, equipment failures in heat) and quantify them. Use this data to identify root causes and areas for improvement (more shade, water, cooling measures, etc.).
  • Action plans with accountability: Convert each finding into a concrete action item tied to a specific metric (goal) and assign an owner responsible for it. This ensures solutions are measurable and someone is accountable for implementing them.
  • Transparent communication: Share a “You said, we did” style update with your festival community after the event. Let attendees know you heard their feedback and show exactly what changes you’ll make to address their concerns – especially regarding heat and safety – to build trust and excitement for next year.
  • Integrate changes into future plans: Don’t treat improvements as afterthoughts. Bake them into next year’s budget, vendor RFPs, contracts, and timelines now. Whether it’s more infrastructure or new protocols, make these fixes part of the festival’s plan from day one so they aren’t overlooked.
  • Adapt to scale and audience: Use these postmortem principles whether your festival is small or massive. The scale of data and response will differ, but listening and learning applies universally. Tailor your solutions to your event’s size, resources, and audience demographics (e.g., family-friendly vs. music rave) for maximum effectiveness.
  • Continuous improvement culture: Foster a team ethos that every festival season is a chance to improve. Celebrate successes from this year but also enthusiastically tackle the shortcomings. Over time, this cycle of feedback and improvement will elevate your festival’s reputation and ensure safer, smoother, and more enjoyable experiences for everyone under the summer sun.
