The UK is set for a return to heatwave conditions this weekend, with forecasters predicting temperatures could reach 32°C in the South of England by Sunday, June 21, 2026. This alert outlines immediate steps you should take to stay safe.
Temperatures are widely expected to climb into the high 20s Celsius across much of the country. The south of England, including Greater London, is forecast to experience the highest temperatures, potentially hitting 32°C on Sunday. Some predictions suggest Greater London could even see temperatures rise to 33°C or even 37°C.
What to do immediately
As temperatures rise, it is crucial to take proactive steps to protect yourself and others:
- **Stay Hydrated:** Drink plenty of fluids, even if you don't feel thirsty. Water is best.
- **Seek Shade:** Avoid direct sunlight during the hottest parts of the day, typically between 11 am and 3 pm.
- **Wear Appropriate Clothing:** Opt for light-coloured, loose-fitting clothing and a wide-brimmed hat if you are outdoors.
- **Check on Vulnerable Individuals:** Look out for elderly neighbours, young children, and those with pre-existing health conditions, ensuring they are coping with the heat.
- **Keep Your Home Cool:** Close curtains or blinds in rooms that face the sun to keep indoor temperatures down. Open windows at night when it's cooler.
- **Avoid Strenuous Activity:** If possible, reschedule demanding physical activities for cooler times of the day, such as early morning or late evening.
Who is affected?
These heatwave conditions will affect residents across the UK, particularly those in the South of England and Greater London where temperatures are expected to be highest. Everyone should take precautions, but particular attention should be paid to vulnerable groups who are more susceptible to heat-related illness.
But there are risks
While 32°C is the widely forecast peak for the South of England, some predictions indicate the possibility of even higher temperatures, potentially reaching 33°C or even 37°C in Greater London. This highlights the importance of not underestimating the heat and remaining vigilant.
What this means for you
Preparing now for the weekend's heatwave can prevent discomfort and potential health risks. Simple actions like staying hydrated and seeking shade can make a significant difference to your well-being and that of those around you.
