Météo-France has placed 37 departments under a red heatwave vigilance alert as extreme temperatures sweep across the country [1].
This level of alert indicates a historic heatwave that poses significant risks to public health and infrastructure. The persistence of these temperatures over a weekend increases the likelihood of heat-related illnesses and stresses the national power grid.
Météo-France said the heatwave is continuing and temperatures will remain very high over the majority of the country this weekend [3]. While some reports indicate the red alert is specifically active for Sunday at 12 p.m. [1], other sources state the alert was maintained through Saturday with a scheduled end time later in the weekend [2, 3].
According to Météo-France, a lifting of the red vigilance alert is planned for 10 p.m. on Sunday, June 28, 2026 [2]. This timeline provides a window for emergency services and local governments to manage the peak of the temperature spike before conditions begin to stabilize.
Beyond the red alert zones, a significant portion of the country remains under orange vigilance. Reports on the exact number of affected areas vary, with figures ranging between 46 [1] and 48 [3] departments.
The current weather event is described as a historic heatwave [3]. Local authorities have been urged to implement heat-health action plans to protect vulnerable populations, including the elderly, and those with chronic illnesses, as the temperatures peak during the final days of June.
“« La canicule se poursuit »”
The use of a red alert—the highest level of vigilance in France—signals an extreme meteorological event that exceeds typical seasonal patterns. By maintaining this alert across 37 departments, the French government is signaling a critical public health emergency that requires immediate intervention to prevent mass heatstroke and mortality, reflecting the increasing frequency of extreme weather events in Western Europe.
