4 Aug
Summary
- Temperatures in parts of France expected to reach nearly 40°C
- Wildfire danger remains high around the Mediterranean
- Storm Floris batters UK with heavy rain and strong winds

As of August 4, 2025, a heatwave is expected to grip parts of France, with temperatures forecast to reach nearly 40°C. According to weather reports, while much of northern France will be cloudy, other regions are expected to enjoy sunny weather, though the extreme heat poses a significant risk.
On August 4, temperatures are predicted to reach 25°C in Cherbourg, 30°C in Paris, and up to 34°C in Gap, 35°C in Toulouse, and 36°C in Alès and Bordeaux. The following day, the mercury is expected to remain high, with 32°C in Lyon, 29°C in Nice, and 36°C in Perpignan, and potentially reaching 39°C in Alès.
The heatwave has also raised concerns about the risk of wildfires, particularly around the Mediterranean region. Earlier this month, a forest fire in southern France, triggered by a sharp temperature spike, spread across an area equivalent to 2,000 rugby fields, forcing the temporary closure of an autoroute to Spain and the evacuation of residents.
Meanwhile, in the UK, the Met Office has issued weather warnings for heavy rain and strong winds, with Storm Floris battering the country with gusts of up to 85mph in some areas.
