The figures speak for themselves: 2025 will rank among the hottest years ever recorded, according to climate experts interviewed by Vert. Even though it could be slightly less scorching than 2024 - the hottest year in history - temperatures remain exceptionally high. Scientists observe an intensification and increased frequency of extreme weather events, with heat waves striking more and more often during festival season.

This climate trend is disrupting the organization of summer events. Festivals, traditionally scheduled between June and August, must now deal with temperatures that can exceed 35°C for several consecutive days. The Mediterranean Sea thus exceeded 30°C in several measurement stations during summer 2024, creating particularly difficult conditions for coastal festivals.

France hosts hundreds of festivals that attract millions of participants each year. The Lorient Interceltique Festival welcomed over 900,000 people in 2022, while Hellfest gathered more than 420,000 festival-goers. These large gatherings represent a major economic challenge, but also a considerable security challenge when temperatures soar.

With Tonight Pass, anticipate weather conditions and choose your festivals with full knowledge for an optimal experience.

Statistics from Public Health France reveal the magnitude of the heat wave phenomenon in France. Since 1990, several episodes have caused thousands of deaths, with a dramatic peak during the 2003 heat wave that killed nearly 15,000 victims. While these data don't specifically concern festivals, they illustrate the danger of extreme heat for the population.

Average temperatures observed during summer festivals:

• Common maximum temperatures: 28-32°C
• Heat wave episodes: 35-40°C
• Exceptional peaks recorded: up to 42°C in certain regions
• Average number of heat wave days per year: 10-15 days (sharply increasing)

Unlike other sectors, less than 5% of festivals are directly canceled due to extreme heat. This resistance is explained by the economic importance of these events and the considerable efforts deployed by organizers to adapt. However, costs related to heat protection measures now represent a significant budget item.

Organizers invest massively in cooling equipment, with budgets that can reach 10-15% of the overall budget for anti-heat wave devices in major festivals.

Extreme heat at festivals presents multiple and sometimes underestimated risks. Dehydration constitutes the primary danger, aggravated by frequent alcohol consumption in this type of event. Symptoms include headaches, dizziness, nausea, and in severe cases, fainting.

Heat stroke represents the absolute medical emergency. It manifests through body temperature above 40°C, hot and dry skin, consciousness disorders that can lead to coma. Without rapid intervention, it can be fatal.

Heat exhaustion particularly affects people exposed to the sun for long periods without protection. It causes violent headaches, nausea, vomiting, and hyperthermia.

Certain audiences require particular vigilance:

• Young children and adolescents: immature thermoregulation
• Elderly people: diminished thermal adaptation capabilities
• Pregnant women: increased risk of complications
• People under medical treatment: possible interactions with thermal regulation
• Alcohol and substance consumers: amplified dehydration

With Tonight Pass, consult specific recommendations for each festival regarding access and health measures.

French regulations impose strict civil and criminal responsibility on festival organizers regarding participant safety. According to the Construction and Housing Code, public-receiving establishments (ERP) are classified into 5 categories according to their capacity, each implying specific obligations.

For festivals welcoming more than 1,500 people, prefectural authorization is mandatory, issued after a safety commission including firefighters. This commission notably verifies electrical installation compliance, presence of fire extinguishers, emergency exit accessibility, and reception capacity.

Although there is no specific regulation for heat waves at festivals, organizers have the legal obligation to "implement all necessary means to minimize risks as much as possible". This includes:

• Providing sufficient drinking water
• Creating adequate shade zones
• Installing cooling points
• Presence of rescue teams trained in heat-related pathologies
• Preventive public information about risks and appropriate actions

The Vigipirate plan imposes additional measures that can complicate heat wave management. Access controls, necessary for security, can create queues under the sun. Organizers must therefore provide misting or shading devices for waiting areas.

Book in advance with Tonight Pass to avoid long queues and access cooled areas more quickly!

Misting cannons represent the flagship innovation in the fight against heat waves at festivals. These devices project fine water droplets up to 60 meters distance, allowing coverage of very large areas. The Garorock festival in Marmande made a sensation in 2019 using this technology, to the point of being featured on France 2's 8 PM news.

These systems offer several advantages:

• Temperature reduction of 5 to 10°C in the influence zone
• Autonomous operation for more than 5 hours
• UV water treatment to eliminate pathogenic microorganisms
• Quick installation and mobility according to needs

Arena Paris also uses this technology to cool outdoor waiting lines during international star concerts like Rammstein or Pink.

Water walls constitute another remarkable innovation. Hellfest has installed 15-meter-wide water walls that create a refreshing curtain particularly appreciated by festival-goers. Combined with four long-range misting devices, they form a complete heat-fighting system.

Cool islands are also developing. Inspired by Parisian urban furniture developed by Climespace (Engie subsidiary), these modular structures offer shade and ventilation in delimited spaces.

Innovation doesn't stop at physical devices. Specialized weather applications allow organizers to precisely forecast heat peaks and adapt their devices in real-time.

Some festivals experiment with body temperature sensors to monitor festival-goer conditions, although this technology raises privacy concerns.

Connected glasses, developed by French startup Auxivia, allow monitoring hydration of vulnerable participants. Although initially designed for nursing homes, they find interesting applications in the event sector.

Providing free water now constitutes a standard in most festivals. Hellfest multiplies water fountains and explicitly authorizes entry with empty bottles, refillable on-site. This simple but effective measure considerably limits dehydration risks.

Some festivals innovate by distributing branded water bottles or in partnership with brands, transforming prevention into a marketing tool while raising public awareness.

Planning shaded rest areas becomes a priority. Beyond natural elements like trees, organizers install temporary structures:

• Giant tents with ventilation
• XXL umbrellas in restaurant areas
• Air-conditioned marquees for VIP zones
• Pergolas with integrated misting

Free distribution of solar protection accessories is becoming widespread:

• Caps and hats in partnership with sponsors
• Sunscreen in automatic dispensers
• Fans in festival colors
• Cooling bracelets for first aid

This approach presents a double advantage: festival-goer protection and marketing visibility for partners.

Good preparation starts several days before the festival. Carefully check weather forecasts and specific organizer recommendations on Tonight Pass.

Your anti-heat wave survival kit:

• Water bottle or reusable bottle (minimum 1.5L)
• Cap or wide-brimmed hat
• UV-certified sunglasses
• Sunscreen SPF 30 minimum
• Light-colored clothing in breathable fabric
• Portable fan or hand fan
• Wet towel in waterproof bag

Hydration cannot be improvised. Drink regularly in small quantities rather than large amounts at once. Prefer cool water and avoid overly sugary drinks that can worsen dehydration.

Warning signs to monitor:

• Intense thirst sensation
• Dry and sticky mouth
• Headaches
• Dizziness or lightheadedness
• Abnormal fatigue
• Decreased sweating

If these symptoms appear, immediately head to a shaded area and rescue teams.

Alternate exposure and protection throughout the day. Actively seek shade zones during the hottest hours (12 PM-4 PM). Take advantage of misting installations and don't hesitate to regularly wet your clothes and hair.

Adapt your alcohol consumption to climate conditions. Alcohol dehydrates and alters perception of your body's alarm signals. If you drink, systematically alternate with water.

Learn to recognize heat stroke signs in yourself and others:

• High body temperature (hot skin)
• Sweating cessation (dry skin)
• Altered consciousness
• Incoherent speech
• Possible convulsions

In case of suspected heat stroke: immediately call emergency services (festival emergency number), put the person in shade, remove excess clothing, apply cool water to the entire body, and provide ventilation.

Jean-Michel Pons, Garorock festival director, testifies: "Installing our misting cannons represented a significant initial investment, but the feedback is unanimous. Not only do we ensure our festival-goers' safety, but it becomes a selling point. People know they can fully enjoy the festival despite the heat."

Hellfest has also noted a clear decrease in heat-related medical interventions since installing its cooling devices. "Our four misting devices and water walls have considerably improved the festival experience," confirms the organization team.

Marie, 28, festival regular: "Before, I dreaded heat waves at festivals. Now, with all these devices, I can really enjoy without constantly worrying about the heat. Garorock's misting zones have become social gathering places in addition to being refreshing!"

Lucas, 22: "Festival weather apps are super practical. I receive alerts on my smartphone when I need to go cool down. It's also reassuring for parents."
