France is in the grip of its most intense early-summer heatwave on record, and several governments have updated their travel advice for the country. You can still travel to France, but you should expect schedule changes, possible flight and rail delays, and real health risks from extreme heat.
Here is what is happening, what is disrupted, and exactly how to protect yourself, with official guidance you can act on. For the wider regional picture, see our coverage of the Europe heatwave and which countries are affected.

A widespread, very intense heatwave has affected mainland France since June 16, 2026. The national weather service, Météo-France, has run its “Vigilance” alert system at the highest levels for more than a week.
At the peak on June 24, up to 58 departments were placed under a red heatwave alert, with around 90 departments under red or orange in total, covering roughly 91 percent of the population. As of June 29, the red alert over Paris and Île-de-France has eased to orange, but the heat has not fully broken.
French health authority Santé publique France has linked roughly 1,000 excess deaths to this episode, so the warnings are not a formality.
Foreign offices are advising caution rather than telling people to stay away. The UK Foreign, Commonwealth and Development Office (FCDO) updated its France advice to flag extreme heat in cities popular with visitors, including Paris, Marseille, Lyon and Bordeaux.
The FCDO notes that dense, older buildings often lack air conditioning, which makes city heat harder to escape. It also warns of a summer wildfire risk along the Mediterranean coast and in Corsica.
Extreme heat has already triggered flight delays at France’s busiest airports. On 20 June, a combination of heat and storm risk delayed hundreds of departures and arrivals at Paris Charles de Gaulle and Paris Orly, with cancellations rippling across European, transatlantic and Middle Eastern routes.
As of June 29, disruption is continuing, though extreme heat is no longer the main driver. Flight-tracking aggregators reported roughly 1,150 delays and around 50 cancellations across French airports in a single day, with Paris Charles de Gaulle the hardest hit (about 477 delays and 13 cancellations) and Paris Orly close behind (about 292 delays and 8 cancellations); Lyon, Nice, Marseille and Bordeaux also saw disruption. The knock-on effects reached international and long-haul routes, with connections toward North America, Asia and North Africa delayed alongside short-haul intra-European services. Industry trackers attribute the current wave mainly to peak-season demand, tight aircraft and crew margins, restrictive air-traffic-control sequencing and storm risk rather than to the heat itself. These figures come from aggregators, not airline confirmations, and change throughout the day, so confirm your specific flight with your airline before traveling.
Heat affects aviation in concrete ways: high temperatures reduce aircraft performance, soften tarmac, and strain ground crews working in the open. Storms that often follow a heat spike add further delays.
Rail travelers should also expect speed restrictions on hot days. France’s strikes and weather can stack up fast, as we saw with the recent Paris airport strike.
Major sights have cut or reorganized their hours, so check before you go. During the peak, the Eiffel Tower and the Louvre cut their opening hours, while Mont Saint-Michel urged visitors to postpone trips during the red alert, to protect staff and visitors.
As of June 29, with the red alert downgraded to orange, those temporary measures have largely ended:
Hours can still shift at short notice if storms or heat return this week, so confirm times on each venue’s official website before you go.
Around 2,000 schools were closed or reorganized at the height of the heatwave, and some outdoor events and tours shifted to early morning or evening slots.
If you are still booking, compare hotels in Paris with confirmed air conditioning, and search flights to Paris with flexible fares in case dates shift.
The single most important habit is to drink water regularly without waiting until you feel thirsty. Santé publique France recommends 1.5 to 2 liters a day, and more if you are active or sweating heavily.
Know the warning signs of heat illness: cramps, headache, nausea and unusual fatigue. Severe signs include confusion, hot dry skin with no sweating, and a fever above 39 to 40 degrees Celsius.
Yes, no government has advised against travel to France. The advice is to take extreme heat seriously, follow Météo-France alerts, and adjust your plans around the hottest hours.
Some flights have been delayed or canceled when heat combines with storms, notably at Paris Charles de Gaulle and Orly. As of June 29, French airports were still recording around 50 cancellations and over 1,000 delays in a single day, though peak-season demand, air-traffic-control limits and storm risk are now bigger factors than the heat. Most flights operate, but check your status before heading to the airport.
Use the Météo-France Vigilance system, which shows red, orange and yellow alerts by department for today and tomorrow.
