A new heatwave is gripping the Paris region at the end of July, with temperatures in the capital expected to reach 37°C this Wednesday. The month of July in Paris has been characterized by successive heatwaves, which notably affected some of the National Day festivities.
Temperatures Soaring to 37°C in Paris
This Wednesday, July 29, 2026, temperatures are set to climb again in the Parisian region, reaching 37°C in the afternoon. The heat will be noticeable from the morning, with 29°C forecast. However, by nightfall, temperatures are expected to drop to a milder 25°C, offering some relief from the daytime heat.
Heatwave vs. Heat Peak: Understanding the Difference
It is important to differentiate between a heat peak and a heatwave. While a heat peak refers to a short, intense period of high temperatures, a heatwave (or canicule in French) implies a prolonged period of abnormally high temperatures, both day and night, over an extended duration. The current situation is described as a “new heat peak” rather than a full-blown canicule, though precautions remain essential.
In the Paris region, heat episodes are often intensified by the urban heat island effect. Concrete, asphalt, and building facades accumulate heat during the day and release it slowly throughout the evening. As a result, even when official temperatures don’t break records, the feeling of heat can be intense in the streets, public transport, and poorly ventilated homes.
Precautions and Outlook for the Week
Temperatures are expected to remain between 28°C and 30°C for the rest of the week following Wednesday’s peak. While this high peak is temporary, it will still be hot, and caution is advised. Essential precautions include regular hydration, avoiding strenuous activities during the hottest hours, seeking shade, and checking on vulnerable individuals.
Staying Cool in Paris: Refreshing Activities
With the ongoing heat, it’s advisable to choose cool spots for outings. Paris offers various options to stay refreshed, such as visiting air-conditioned museums, enjoying public swimming areas, or spending time in parks with ample shade. Local authorities also recommend utilizing municipal shower facilities, which are free and accessible to all.
Transport Disruptions and Urban Planning
The heatwave coincides with significant disruptions to public transport in Paris and the Île-de-France region. From July 27 to August 2, 2026, the RER B line will experience partial closures from Gare du Nord, according to RATP and SNCF. Additionally, the République metro station on Line 8 will be closed for nine months starting July 22, 2026, due to renovation work. The RER A line will also see the Nation station closed for two months, from June 29 to August 30, 2026, and the central section of RER B will be interrupted from July 25 to August 16, 2026.
These transport disruptions, combined with the heat, highlight the challenges faced by residents and visitors. The city’s efforts to mitigate the urban heat island effect and provide cooling options are crucial during such periods. The Olympic cauldron for Paris 2026 is also on display at the Tuileries Garden until September 14, 2026, offering a cultural attraction.
The city’s initiatives include opening free dog exercise areas in parks like Parc Monceau until October 2026 and reintroducing swimming areas in the Marne at Joinville-le-Pont until August 31, 2026, and in the Canal Saint-Martin’s Bassin des Récollets. These measures aim to enhance urban living and recreational opportunities amidst the summer heat.
