A yellow heat-health alert for the South East will be escalated to amber and will be in place from 9am on Wednesday 8 July until 9pm on Sunday 12 July 2026
The UK Health Security Agency (UKHSA) has issued updated heat-health alerts (HHA) for all regions in England, warning that rising temperatures this week may increase health risks, particularly for vulnerable groups.
The existing yellow heat-health alert for the East Midlands, West Midlands, East of England, London, South East and South West will be escalated to amber and will be in place from 9am on Wednesday 8 July until 9pm on Sunday 12 July. The yellow heat-health alert will remain in place until then.
A yellow heat-health alert has also been issued for the North West, North East and Yorkshire and the Humber and will be in place for the same time period, from 9am on Wednesday 8 July until 9pm on Sunday 12 July.
Dr Agostinho Sousa, Head of Extreme Events and Health Protection at UKHSA, said:
Sustained periods of warm weather can result in serious negative health outcomes across the population, so it is important that everyone takes sensible precautions while enjoying the sun. Based on the current forecast, we don’t currently expect the health impacts to be as high as the heatwave we saw at the end of June but older adults and those with pre-existing conditions are still at risk.
If you have friends, family, or neighbours who are more vulnerable, it is important to check in on them and ensure they are aware of the forecast and are following the necessary advice.
Simple steps such as staying hydrated, avoiding the sun during the hottest part of the day, and keeping your home cool are effective ways to help keep yourself and others safe during periods of hot weather.
UKHSA will continue to monitor and update alerts if necessary.
