Another very hot day in Richmond, reaching 34°C — UV index at 9

Richmond is in for another scorching day today, with the Met Office forecasting a high of 34°C, sunshine throughout the day and only a 5% chance of rain. The overnight low is 22°C, meaning little relief even after dark.
The UV index is forecast at 9, which is classed as very high — meaning unprotected skin can burn quickly even on a walk to the shops. Sun cream, a hat and plenty of water are strongly recommended if you are spending any time outside, particularly with children or elderly relatives.
Richmond Park, the riverside path and Terrace Gardens will be busy, so earlier morning visits are likely to be more comfortable. The park's Isabella Plantation offers some shade, and the Thames towpath benefits from a breeze off the river in the afternoons.
Heat-health guidance from the NHS suggests staying out of direct sun between 11am and 3pm, keeping indoor spaces cool by closing blinds during the day, and checking in on neighbours who may be more vulnerable in sustained high temperatures. This warm spell has now extended across much of the week — if the heat is affecting you, the NHS 111 service is available online and by phone.
