What restrictions are introduced when France faces a heatwave?

Reader Question: Are there any rule changes I should be aware of when there are heatwave alerts in my area? Do I need to make any changes in my daily life?

Daily life changes considerably in France during periods of heatwave and 2026 is unusual in the long-lasting impacts in some areas.

Three major heatwaves in under two months have seen some departments face multiple weeks of heatwave warnings.

It means that several restrictions or changes usually in place only for a short period of the summer have already been introduced up to three separate times. 

It can be confusing to keep track. 

Météo France issues warnings that authorities follow

A key resource for heatwave restrictions is the website of state forecaster Météo France. 

It publishes alerts for all types of extreme weather conditions, and since 2004 has also done so for canicule (heatwave) conditions following a major 2003 heatwave.

Its alerts use a tiered and colour-coded system: green means no alert; yellow means people are invited to act with caution, stay informed of conditions and adapt their behaviour; orange means you should be very careful as dangerous weather conditions are expected and residents are asked to follow safety advice; and the most severe red alerts come with major warnings for health and safety. 

You can click on your department on a Météo France map for more details of the situation in your area. 

These canicule alerts are tied to day and night-time temperatures in departments, which must reach above a certain level for three consecutive days for warnings to be implemented. Temperatures are tied to local seasonal norms, to ensure they are accurate for the department’s location. 

However, other factors also influence them including pollution, humidity, how long it has already been hot, the number of potentially vulnerable people in the department, etc.

Météo France’s canicule alerts, as such, do not include legally enforceable restrictions, but rather advice to be followed. 

For example, advice in red alert areas typically includes actions such as drinking water regularly throughout the day, avoiding going outside during the hottest part of the day, wearing a hat and light clothing if you do need to go out, limiting strenuous physical activity, keeping shutters, curtains and windows closed during the day and ventilating your home at night. 

People are also advised to spend a few hours a day in an air-conditioned or otherwise cool place where possible, check on elderly or vulnerable neighbours and relatives, and call a doctor if they feel unwell.

Residents are also urged to avoid activities that could start vegetation fires, such as using equipment that produces sparks or carelessly discarding cigarettes or using barbecues.

The issuing of orange warnings or higher typically also sees the introduction of local authority ‘heatwave plans’ in the impacted departments, which are further strengthened during red alerts.

This mobilises additional services for health and social care, opens shelters for vulnerable people, and sees departmental authorities contact individuals on its heatwave register to check on their wefare. 

France’s recent severe heatwaves have seen the government issue emergency health plans at a national level, providing greater funding and additional services for the most vulnerable. 

Several local rule changes

There are several other local restrictions that authorities have the power to implement during periods of hot weather, either directly due to the heat or because it is a contributing factor for other potential issues.

Most notable of these would be water restrictions. 

Extended heatwaves can exacerbate summer droughts, drying soils and making it difficult for rainwater to penetrate to aquifers even when it does rain. 

Restrictions, mostly on tap water but also on water from rivers and wells, are implemented at a communal level by local authorities. 

Typical restrictions for residents include a ban on watering gardens, washing vehicles, cleaning outside areas of your home such as roofs and driveways – all of these either at certain hours or via a blanket ban – as well as filling or topping up swimming pools. 

In the most extreme cases, water can only be used for necessary purposes such as cooking and personal hygiene purposes.

The VigiEau website provides real-time updates of restrictions using its map and is interactive, allowing people to enter their postcode to see exact restrictions.

Heatwaves also greatly increase the risk of forest fires. 

Departmental prefectures can therefore ban certain activities such as building or renovation works during periods of hot weather, hosting of barbecues, holding of certain outdoor events and entering certain forested areas.

Prefectures update this information daily based on the risk of forest fires in the local area, usually using the Météo France forest fire risk map but also from local information. 

You can check the prefecture website, or with your mairie, to see if there are restrictions for you. 

Prefectures can also limit sales of fireworks – notable for the July 14 celebrations held across France on its national day – and several communes have chosen to postpone firework shows due to the risk of fire.

While not directly related to heatwave conditions, the high temperatures greatly increase the chance of fires, with authorities erring on the side of caution.

Highlighted during the record-breaking June heatwave, departments can also introduce temporary bans on alcohol sales and consumption during heatwave periods. The bans generally apply to drinking alcohol in public places, as well as ‘take-away’ sales of alcohol.

Drinking in venues (such as bars) is not typically banned. 

While there are no nationwide changes to driving rules (such as lower speed limits), heatwave conditions can lead to pollution spikes that in turn see departments implement temporary driving rules. 

Drivers are however urged to remain sensible when driving in extreme heat, using air conditioned vehicles where possible, staying hydrated and avoiding drinking alcohol, and attempting to avoid driving when temperatures are warmest (roughly between 12:00 and 16:00) or at rush hour.

Be careful about washing your car – even at a car wash – as water usage restrictions will impact this. 

Certain cultural or tourist attractions may also close, particularly if they expect large crowds and do not have air conditioning. 

This includes the Eiffel Tower, as well as the Louvre and Orsay museums in Paris.

Work and school rules 

Schools and workplaces can also be impacted. 

During extreme temperatures, schools can opt to cancel certain outdoor classes or activities, or close early (the afternoon is the hottest part of the day). 

In some cases, schools shut completely due to the heat.

Parents will be directly informed by schools of any changes.

Unlike European countries such as Germany, France has no ‘maximum’ temperatures for working. 

This means there are no blanket, nationwide rules allowing staff to work from home or have days off if temperatures reach a certain threshold. 

Employers may offer this to workers, but are not obliged to regardless of conditions. 

This being said, at temperatures of 33C and above companies must “ensure the safety and protect the physical and mental health of workers,” as stated in article L4121-1 of France’s employment code.

This can include measures such as reducing the level of physically heavy work, providing fresh drinking water (and shade for outdoor workers) and altering working hours to avoid the peak heat. 

Employers are not required to implement heat-reducing measures (such as blackout blind, air conditioning, etc) due to heat, but most offices now have at least something in place.

Refusal to work is only possible if employers do not meet these conditions, but workers should discuss matters with their Comité social et économique or directly with management before walking out.
