Amber and yellow heat-health alerts are active across England as the UK braces for a historic, prolonged heatwave.
The UK Health Security Agency (UKHSA) officially issued the amber heat-health alerts on Monday, 6 July 2026.
The warnings are scheduled to remain active from 9:00 AM on Wednesday, 8 July until 9:00 PM on Sunday, 12 July 2026. They cover regions across the Midlands, eastern, and southern England.
Temperatures are forecast to soar up to 36°C (97°F) in parts of southern England this week. However, the weather will vary sharply by region, ranging from the mild mid-20s in the north to intense mid-30s in the south.
The UK Health Security Agency (UKHSA) has placed the Midlands, eastern, and southern England under an amber heat-health alert until 21:00 BST on 12 July. Concurrently, a yellow alert is active across northern England.
Health officials warn that the sustained high temperatures will severely strain health and social care services. A spike in mortality rates is anticipated, posing the greatest threat to individuals over 65 and those with underlying health conditions.
The summer heatwave is officially underway, locking down the South and East on Monday after three straight days of scorching weather.
The hot zone expanded significantly on Tuesday, pushing the mercury to 32.4°C in Teddington and Frittenden. This is just the warmup: temperatures are on track to peak by Friday, with southern England bracing for maximums of 34°C to 35°C.
The heat will continue to intensify, spreading north and west into Scotland and Northern Ireland until Friday, where temperatures are expected to peak in the high 20s.
As high pressure shifts toward the weekend, an incoming easterly breeze will bring welcome relief to eastern parts of the UK. This will push the core of the heatwave further west, locking intense temperatures over central southern England and driving highs up to 33°C in South Wales by Friday.
Lower humidity levels this week mean temperatures above 30°C will feel less oppressive than the heatwave in late June. Overnights will stay warm but should generally be more comfortable than last month.
The main exception will be major towns and cities, where “tropical nights” could keep evening lows above 20°C later this week.
How long will the heatwave last?
While not record-shattering like May or June, this event stands out for its stamina. It could become one of the longest-lasting heatwaves since 1976, when England recorded up to 16 consecutive days above 30°C.
With the South staying above its 27°C–28°C threshold through next week, the official heatwave could stretch to a full 14 days in some locations.
