The UK Health Security Agency (UKHSA) and the Met Office have issued an amber heat-health alert (HHA) for five regions of England, including London.
The alert is currently in place from 12 noon today (Friday 27 June) to 6pm on Tuesday 1 July. The weather will get steadily warmer in the coming days, peaking on Monday when much of the country will see temperatures in the early to mid-30s degrees Celsius (°C).
Heat, especially at the sort of temperatures forecast for the beginning of next week, can result in serious health outcomes across the population, especially for older adults or those with pre-existing health conditions.
It is therefore important to check on friends, family and neighbours who are more vulnerable and to take sensible precautions while enjoying the sun.
There are additional ways in which you can keep yourself and others safe during periods of hot weather, such as:
- keeping your home cool by closing windows and curtains in rooms that face the sun
- if you do go outside, cover up with suitable clothing, such as an appropriate hat and sunglasses, and seek shade and apply sunscreen regularly
- keeping out of the sun at the hottest time of the day, between 11am and 3pm
- if you are going to do a physical activity (for example, exercising or walking the dog), plan to do these during times of the day when it is cooler, such as the morning or evening
- knowing the symptoms of heat exhaustion and heatstroke and what to do if you or someone else has them
