UK heat-health alerts expanded as 36C expected

Amber alerts widen as temperatures climb

The UK Health Security Agency has expanded heat-health alerts across most of England as forecasters warn temperatures could peak at around 36C on Friday.

The amber warnings came into force at noon on July 9 and are set to run until 9pm on Sunday, July 12. The North East remains the only English region not under amber cover, staying on yellow instead.

The UK is now in its third heatwave of 2026, with the Met Office saying the hottest conditions are expected on July 10.

Health services on alert

UKHSA said the amber level indicates a potential risk to the whole population and could add pressure on the NHS, including GPs and ambulance services.

Dr. Agostinho Sousa urged older adults and people with pre-existing conditions to take precautions, including staying hydrated and avoiding the hottest part of the day.

The Met Office also said July 9 was the eighth day in 2026 with temperatures above 34C, setting a new yearly record ahead of 1976 and 2020.

Wider disruption risk

Officials are also warning that dry, sunny and windy conditions are increasing wildfire risk, especially along southern and eastern coasts.

The heat has already prompted disruption in parts of the country, with schools in some areas closing early as temperatures rise.

Forecasters said the southeast should begin to ease over the weekend, but warm weather is expected to continue into next week.
