Another scorcher in Richmond today — high of 34°C with UV index 8
9 July 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
Wednesday is set to be the hottest day of the current spell so far, with the Met Office forecasting a high of 34°C in Richmond — up two degrees on Tuesday's 32°C peak. It will be partly cloudy for much of the day, which may offer some relief from direct sun, and the chance of rain remains negligible at just 5%. The overnight low will stay at a warm 22°C, so another uncomfortable night is likely for those without air conditioning.
The UV index is 8 (very high), meaning unprotected skin can burn quickly even on a cloudy day. The NHS recommends applying SPF 30 or above, wearing a hat and staying in the shade between 11am and 3pm.
Richmond Park and the riverside will be busy — if heading out, take plenty of water, apply sunscreen and check on elderly or vulnerable neighbours who may struggle in the heat. The park's car parks fill early on hot days, so cycling or public transport is a practical alternative.
