The next UK heatwave is most likely during summer 2026, but isolated warm spells could appear earlier if high pressure settles. The live ranking above shows current regional probabilities, while a storm to hit Britain this weekend will keep temperatures below average for now.
When is the next heatwave expected?
Most long-range models suggest the next widespread heatwave – defined as three consecutive days above a regional threshold – will occur between June and August 2026. However, short-lived warm snaps are possible in late spring if blocking patterns develop. For a detailed outlook, see the 10 Day Weather Forecast UK.
What weather should we expect before then?
A storm is expected to hit Britain this weekend, bringing heavy rain and gusty winds. The Moderate Rainfall Warning remains in place for parts of the country. After that, conditions gradually turn more settled, but no sustained heat is forecast for at least the next 14 days. Check the uk weather forecast 14 days for updates.
When will it start getting warmer in the UK in 2026?
The uk weather forecast 14 days shows variable conditions into spring. Long-range models suggest a gradual warming trend from late April, with the first real heatwave likely in June or July 2026, depending on atmospheric patterns.
How likely is a heatwave map for 2026?
The next heatwave uk map (the live ranking above) gives region-by-region probabilities based on ensemble forecasts. For 2026, southern and eastern England show the highest likelihood, while northern and western areas remain less certain.
What should I do to prepare for a heatwave?
NHS advice recommends staying hydrated, avoiding direct sun between 11am and 3pm, and checking on vulnerable neighbours. The RSPCA also urges pet owners to provide shade and water. No immediate action is needed, but it’s worth reviewing advice now.
