- Forecast of a major pan-European heatwave

- Heat and humidity expected to affect large parts of western Europe
- Azores high-pressure systems are expected to drive the weather pattern
- Wildfire risk may increase in hotter regions
A major heatwave is forecast to affect much of Europe over the next two weeks, with the strongest heat expected in Spain, Portugal and especially France. Forecasts suggest temperatures could reach around 43C in parts of northeastern France, while some sources warn that the hottest areas in Spain and Portugal could see even higher readings locally.
The Netherlands and Belgium are expected to sit closer to the edge of the heat plume, meaning conditions there may be less extreme than farther south and east. Even so, forecasters say the air will feel very muggy at times, with high humidity likely to make the heat uncomfortable, particularly for older people and those with respiratory problems.
The warm spell is being linked to repeated extensions of the Azores high-pressure system, which are expected to steer hot air northward from North Africa across the European mainland. Meteorologists say the pattern could keep a broad heat dome in place through the end of June, with the first widespread peak heat arriving late in the week and into early next week.
The forecast also raises the risk of wildfire conditions in the hardest-hit areas, especially in the Iberian Peninsula and parts of France. While there are signs that a cooler Atlantic breeze could eventually ease conditions as July approaches, the immediate outlook remains dominated by intense heat across much of western and central Europe.
Why This Matters
This heatwave forecast signals an immediate health risk, especially for the elderly and those with respiratory issues in affected regions. It also heightens wildfire danger in the Iberian Peninsula and France, potentially disrupting travel, agriculture, and energy demand. Readers should prepare for extreme heat and monitor local warnings.
