Scorching Heat for the Summer Solstice: The Dangerous Longevity of Europe’s New June Heatwave
Key Points:
- A massive Heat Dome is forming over Western Europe, trapping scorching Saharan air and triggering an intense early-season heatwave from the Iberian Peninsula to Western European capitals.
- Portugal and Spain could see temperatures reaching up to 45 °C (113 °F), while cities like Paris may experience multi-day highs in the upper 30s to low 40s Celsius, significantly above seasonal averages.
- The heatwave is driven by a strong upper-level ridge originating from Northwest Africa, causing sinking air that compresses and warms surface temperatures, with the phenomenon expected to persist through June.
- The prolonged heat poses serious health risks, especially to vulnerable populations and outdoor workers, and may exacerbate drought conditions and wildfire risks due to already dry soils in many regions.
- Temperatures will gradually spread north and east across Europe, with France, Benelux, the UK, and parts of Italy and the Balkans experiencing significant warmth, while the heatwave is forecast to be long-lasting without major weather disturbances.
