EU heat dome grips southern Europe as UK faces patchy warmth

What's happened

Heat dome over Europe is driving extreme temperatures in southern France, Spain and Italy, with 38C-42C in low-lying areas. The UK is seeing a late-summer rise to the mid-20s, but conditions are set to cool next week as Atlantic air moves in. Forecasts warn of continued unsettled weather later in September.

What's behind the headline?

Analysis

• The heat dome signals a broader pattern shift, with North African air intrusions becoming more common in southern Europe.
• Predictive models show a high-pressure lid persisting into the coming days, which will keep Spain, France and Italy hottest while UK warmth is short-lived.
• If temperatures exceed forecasts in Spain and Italy, wildfire risk could spike, stressing already dry landscapes.
• The developing pattern could prompt policy discussions on cross-border heat management and wildfire preparedness.
• Readers should monitor local alerts as conditions may change quickly with Atlantic fronts.

Tone and forecast

• Expect highs to remain in the upper 30s to low 40s Celsius in southern valleys and coastal zones; much of northern Europe stays cooler but unsettled patterns persist.
• The UK faces a brief warm spell this weekend, followed by a cooler week with more rain, as Atlantic air returns.
• This will influence energy demand, water use and outdoor planning across the continent.

How we got here

An expanding high-pressure system is pushing hot, dry air from North Africa into southern Europe, creating a heat dome that intensifies this week. Authorities warn of drought and wildfire risks as conditions remain parched. UK temperatures rise briefly this weekend before cooler conditions return.
