New weather maps have turned a volcanic red as the UK braces for a nine-day heatwave that will push temperatures to 32C and beyond, particularly in the South East. After a brief respite from recent sweltering conditions, the mercury is set to climb again from next Thursday, with some areas reaching 34C.
Nine-day scorcher ahead
The prolonged hot spell is expected to last from Thursday, July 9, through to Saturday, July 18, according to forecasts. The South East will bear the brunt, with heat maps showing deep red across the region for most of that period. London and the surrounding areas are likely to see the highest temperatures, with Saturday, July 11, forecast as the hottest day, exceeding 30C across much of the South and South East.
In the north of England, temperatures will be slightly lower, peaking just under 30C on the hottest days. However, the heat will still be significant, and a yellow heat warning has been issued, coming into effect at 12pm on Saturday, July 4.
Comparison to recent records
While this heatwave is intense, it is not expected to break the record set in June 2026, when the UK experienced its hottest June day ever, reaching 37.7C in Lingwood, Norfolk. That temperature was more than two degrees higher than the previous record set in 1976. Nonetheless, the upcoming heat may still catch people off guard.
Health advice and precautions
Health officials advise closing curtains and windows during the hottest parts of the day and only travelling if necessary. The yellow heat warning indicates that there is a potential risk to health, especially for the elderly, young children, and those with underlying health conditions. It is recommended to stay hydrated, avoid strenuous outdoor activities during peak heat, and check on vulnerable neighbours.
