Overview

• Meteorologists expect temperatures to climb steadily from Wednesday, peaking Friday with widespread highs of 34–35°C and possible 38°C readings in southern regions.
• A persistent blocking omega pattern will establish a high-pressure dome over France, cutting off Atlantic disturbances and ensuring dry, hot conditions.
• Météo-France warns that if daytime highs remain above 35°C for at least three consecutive days, the episode will qualify as a canicule and prompt health advisories.
• Northern departments such as Nord and Pas-de-Calais could see 28–31°C by the weekend, while interior and coastal areas from the Massif Central to Corsica also face significant heat.
• Forecasters note the potential to challenge June temperature records, with this stretch of heat poised to rank among the warmest on record.
