France's heatwave protection system
France operates a comprehensive heatwave response system established in 2004, one year after the catastrophic 2003 heatwave that claimed approximately 15,000 lives. That disaster, which primarily affected elderly people over 75 years old, prompted the creation of the National Heat Wave Plan and the Heat Wave and Health Alert System.
The measures implemented since then have proven remarkably effective. During the 2019 heatwaves, mortality was reduced by approximately 90% compared to 2003, with around 1,500 deaths versus more than 15,000 in 2003.
Orange-level heatwave alerts are triggered when biometeorological indicators reach or exceed departmental thresholds for three consecutive days and nights, posing a health risk to the entire exposed population.
Current situation
France is experiencing its fifth heatwave of 2026, with state forecaster Météo France placing 43 departments on orange alert on Tuesday, rising to 67 departments by Wednesday. Temperatures are expected to reach near 40C in many areas, with only the far north escaping the intense heat.
The frequency of such events marks a dramatic shift from historical patterns. Before 1989, heatwaves in France occurred on average once every five years, but since 2000 they have recurred annually. This fifth heatwave of the summer underscores the increasing intensity of extreme weather patterns affecting the country.
Tuesday's forecast shows temperatures reaching 30C to 32C in the north, climbing to 34C in Paris, 37C in the Loire Valley, and 36C in the south-west. Skies will remain mostly clear except in the south-east, where storms will persist. The heatwave is expected to continue through the weekend.
Adding to the severity of the situation, approximately 70% of France is currently experiencing drought conditions, with 67 departments under drought crisis measures or heightened alert levels. Water-use restrictions remain in place across much of the country.
Protecting vulnerable residents
Vulnerable people including those over 65, individuals living alone, disabled persons, and pregnant women can register free of charge on local heatwave registers. During periods of extreme heat, authorities contact registered households by telephone to ensure their wellbeing, provide cooling advice, and conduct welfare checks.
If a person appears to be in difficulty or fails to respond when authorities deem it concerning, local police or gendarmes can conduct in-person checks. The system specifically targets demographics identified as most at risk following the 2003 disaster, when elderly women over 75 were disproportionately affected.
For ongoing monitoring outside official heatwave periods, La Poste offers its 'Veiller sur mes parents' service, where postal workers conduct welfare checks one to several times weekly on elderly residents, though this requires a monthly subscription.
Workplace protections during extreme heat
Unlike some European countries, France has no maximum temperature threshold that automatically limits professional activity. However, at temperatures of 33C and above, companies must ensure worker safety and protect physical and mental health under article L4121-1 of France's employment code.
Required measures can include providing fresh drinking water and shade for outdoor workers, adjusting work hours to avoid the hottest periods, and reducing physically demanding tasks. Many companies now have internal heatwave policies allowing remote work or time off when certain temperature thresholds are reached or specific alert levels are activated.
Workers who feel their safety is not being adequately protected should raise concerns with human resources, direct management, or their worker representative body.
Driving and transport considerations
While national speed limits remain unchanged during heatwaves, drivers are strongly advised to modify their behaviour. Alcohol has greater impact during hot weather due to dehydration and sweating, so limits should be stricter than usual. Long motorway drives should be avoided during the hottest parts of the day when possible, and vehicles should be stocked with fresh water, food, and cooling supplies in case of traffic delays.
Rail services can experience cancellations on certain routes as France's rail system struggles with intense temperatures, though passengers should receive reimbursement or ticket exchanges. Local public transport including metros, trams, and buses typically continue operating but can become extremely hot and crowded.
Emergency response measures
The government can now implement a heatwave-specific version of civil-security Orsec plans, first activated in July 2026. These plans allocate additional funding and resources to hospitals and public services, increase welfare checks on vulnerable residents, and prepare for patient surges.
Updates to the plan following its initial implementation added local cooling centres that open during heatwaves, where people can benefit from air conditioning and other cooling measures. In extreme cases, vulnerable residents in buildings deemed too hot can be evacuated to these centres.
Local authorities can also enact heatwave plans including restrictions on outdoor activities, altered building opening hours, and even limits on alcohol sales. Hospitals may implement 'plan blanc' emergency protocols to prepare for increased patient admissions.
Pet safety guidance
Animals face significant risks during extreme heat. Pets should be kept in the coolest areas of homes with access to fresh water, and their time in direct sun should be limited. Dogs should only be walked during cooler periods in early morning or evening, never during midday when paws could be burned on hot surfaces.
Pet fur should not be cut, as it provides protection from heat and certain illnesses. Younger animals require extra attention as they struggle to regulate body temperature. Owners concerned about symptoms should contact a veterinarian immediately.
Air conditioning and cooling systems
France is promoting heat pumps as the primary ecological cooling solution. Recent funding measures include VAT reductions and potential leasing systems to spread installation costs. These systems can both cool homes in summer and provide heating in winter.
However, heat pump adoption has faced challenges. Sales dropped significantly from 355,000 air-to-water units in 2022 to 185,000 in 2025, despite government promotion and financial incentives.
Installation of certain air-water pumps falls under the MaPrimeRénov' government aid scheme, with low and modest income households eligible for state assistance. Standard air pumps are only covered when installed alongside at least one other project. Installation in shared buildings requires approval from other residents and can take considerable time.
There is limited direct aid for standard air conditioning units that increase rather than reduce household energy usage, as these do not align with France's environmental goals.
