Southern France Faces Intense Heatwave with Temperatures Above 40°C on June 13, 2026

On June 13, 2026, southern France is enduring a severe heatwave, with temperatures soaring above 40°C in parts of the region. This intense heatwave has struck the southern half of the country, known as the Hexagon, marking a major weather event as reported by Le Monde. The heatwave is expected to intensify starting Tuesday, moving northwards, potentially causing temperatures across France to reach or exceed 40°C.

Today, most of France experiences bright sunshine apart from the North Atlantic region, where cloud cover persists. Temperature variations range widely with Amiens at a cool 14°C, while Mimizan in the south records highs climbing up to 38°C, according to France Info. The southern regions, including Corsica and the Gulf of Lion, enjoy clear skies in the morning, though clouds are forecasted to develop in some northern and northwestern parts later in the day.

This heatwave is significant due to its intensity and spatial reach, affecting a large part of France with potential health and environmental impacts. The forecast for Sunday suggests a continuation of sunny weather with some cloudiness in specific areas like the Alps, and temperatures remaining elevated, underscoring the persistence of severe heat conditions.

Officials and residents are urged to prepare for escalating temperatures, especially from Tuesday onward when the heatwave is projected to intensify further and spread across more northern regions. This will likely expand the challenges associated with sustained extreme heat across France.
