Heatwave alert

London is experiencing a heatwave that is expected to last until 9am on Thursday 22 June. In London, two or more days in a row of temperatures above 32 degrees is considered a heatwave.

Residents are advised to stay out of the sun where possible, drink plenty of water, and carry a water bottle when walking or using public transport. Try to do your exercise early in the morning or later in the evening when it is cooler.

Keep your home as cool as possible – shading windows and shutting them during the day may help. Open them when it is cooler at night.

If there's anybody you know, for example an older person living on their own, who might be at special risk, make sure they know what to do.

Keep pets indoors with plenty of fresh water, and never leave a pet in a parked car.

We are working with our partners to make sure our most vulnerable residents are safe and know what to do.

For more advice on how to reduce the risk for yourself or somebody you know, visit NHS Choices at nhs.uk/summerhealth, call NHS 111 or speak to your local chemist.
