15 July 2022
Temperatures close to 40C are possible in NW London (as well as Greater London and some other regions) on Monday 18 July and Tuesday 19 July 2022.
A Level 4 heat-health alert has been issued.
The UK Health Security Agency provides these tips for hot conditions:
- look out for those who may struggle to keep themselves cool and hydrated – older people, those with underlying conditions and those who live alone are particularly at risk
- stay cool indoors by closing curtains on rooms that face the sun – and remember that it may be cooler outdoors than indoors
- drink plenty of fluids and avoid excess alcohol
- never leave anyone in a closed, parked vehicle, especially infants, young children or animals
- check that fridges, freezers and fans are working properly
- try to keep out of the sun between 11am to 3pm, when the UV rays are strongest
- walk in the shade, apply sunscreen and wear a wide-brimmed hat, if you have to go out in the heat
- avoid physical exertion in the hottest parts of the day
- make sure you take water with you if you are travelling
- take care and make sure to follow local safety advice if you are going into the water to cool down
- check medicines can be stored according to the instructions on the packaging
Conditions are set to remain hot before and after this period.
