The essentials
France enters third heat wave with 59 departments under alert and temperatures reaching 40°C in the southwest.
France is entering its third heat wave of 2026, with 16 departments placed on orange alert and 43 additional departments on yellow alert. Temperatures have reached 40°C in southwestern France, particularly in the Toulouse and Haute-Garonne regions.
Météo-France characterizes this heat wave as durable but less intense than the previous episode. The system is expected to persist through mid-July with no rain forecast, creating sustained heat stress across much of the country.
The orange alert designation indicates heightened concern, while the broader yellow alert coverage reflects the geographic scope of the temperature anomaly. The absence of rainfall prolongs conditions that have already strained emergency services managing concurrent wildfire activity across southern France.

Orange and yellow alert coverage expands across 59 French departments
Sixteen departments are now on orange alert for the third heat wave, with 43 additional departments on yellow alert, reflecting the geographic breadth of elevated temperatures. This two-tier alert system allows authorities to calibrate response intensity based on local conditions. The alert designations guide public health measures and resource allocation across regions experiencing temperature anomalies.
Third heat wave expected to persist through mid-July without precipitation relief
Météo-France forecasts the heat wave will continue through mid-July with no rain in sight, establishing conditions of prolonged thermal stress. While less intense than the previous heat wave, the duration compounds heat exposure risks. The absence of precipitation maintains elevated wildfire risk across already-stressed southern regions.
