Early-Season Heatwave Scorches Western Europe

Overview

• A strong high-pressure ridge has driven unusually hot air from North Africa over Western Europe, producing temperatures more than 10°C above typical May levels.
• The episode intensified over the weekend, with Paris reaching 31.9°C on Sunday and the Met Office recording 34.8°C at Kew Gardens on Monday.
• Authorities have raised alert levels across several countries, including orange and yellow heat warnings in multiple French departments and Met Office health alerts in regions of England.
• The heat has had immediate human impacts: a participant died during a Paris race on Sunday, about a dozen runners were hospitalized in Maisons-Alfort, and some sporting events were canceled in the Alpes-Maritimes and Menton.
• Scientists and national weather services link the early and extreme timing of the heat to broader warming trends and say the persistence of the air mass could disrupt public health, infrastructure, and outdoor activities over the coming days.
