Another scorching day ahead for Richmond, topping 35°C
24 June 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
Wednesday is shaping up to be the hottest day of the week so far, with the Met Office forecasting a high of 35°C in Richmond — a degree warmer than yesterday's already sweltering peak. Sunshine is expected throughout the day, with the overnight low staying mild at 22°C and just a 1% chance of rain. The UV index sits at 9, which is classed as very high, meaning unprotected skin can burn quickly even in brief spells outdoors.
Anyone spending time outside — whether at Richmond Park, Terrace Gardens, or the riverside at Twickenham — is advised to apply high-factor sunscreen, wear a hat, and drink water regularly. The hottest part of the day is typically between noon and 4pm, so early mornings and evenings are the better windows for exercise or walking the dog.
The elderly, young children and those with certain health conditions are most vulnerable in this kind of heat; it is worth checking in on neighbours who may struggle. NHS guidance recommends keeping windows shaded during the day and opening them at night to let cooler air circulate.
