Overview

• Temperatures will exceed the 25°C heat threshold across much of northern France, with Paris potentially reaching 30°C on Thursday and Friday.
• Météo France has classified this unusual event as an 'épisode de chaleur précoce,' driven by a North Sea anticyclone and a Portuguese depression pulling hot air from North Africa.
• Reims is forecast to hit 27°C on Wednesday, making it one of the hottest cities in France during the early stages of this heat episode.
• Despite the high temperatures, this event will not qualify as a national heat wave, as the average national temperature will remain below the 25.3°C threshold.
• Similar early heat episodes occurred in 2005, 2018, and April 2024, but climatologists note that April temperatures have been rising rapidly in recent decades.
