The UK is facing its most intense heatwave yet in 2026, with temperatures set to soar to a sizzling 38C in some areas. A Met Office-issued Level 3 Amber alert has been triggered for much of England, highlighting an extremely high risk to vulnerable individuals and the general public.
Central and southern England are bracing themselves for the worst of it, with forecasters predicting highs in the mid-to-high 30s. But other regions won't escape the heat either: northern England is expected to reach lows of 32C, while Wales will see temperatures hover around 31C. Even Scotland and Northern Ireland, which usually enjoy milder summers, are facing highs in the late 20s – well above average for this time of year.
The Met Office says a hot plume from continental Europe is to blame for the intense heat. With light winds averaging below 10mph across most areas, the stifling conditions will feel even more oppressive. Night-time temperatures will remain high too, making it harder to get some respite and potentially disrupting sleep patterns.
Health experts are sounding the alarm, urging people to take precautions against the heat. The Level 3 Amber alert – issued in partnership with the UK Health Security Agency (UKHSA) – signifies a significant risk to health, particularly for older folk, young children, and those living with pre-existing medical conditions.
Regional hotspots include Yorkshire and the Humber, East Midlands, West Midlands, East of England, and South East England. Even in areas expected to experience slightly lower temperatures – like the North West and South West – the prolonged heat poses a significant challenge. Across Scotland, Wales, and Northern Ireland, health authorities are advising caution and recommending sensible precautions against the heat.
