Another hot one: 29°C forecast for Richmond today with strong UV

Thursday is shaping up to be a scorcher in Richmond, with the Met Office forecasting a high of 29°C, a low of 17°C overnight and just a 5% chance of any rain. The UV index is 8 — firmly in the 'very high' category — so sun cream and shade are genuinely important, especially for children and anyone spending time outdoors for extended periods.
With 25 of the borough's parks having just been awarded Green Flag status, there are plenty of well-maintained green spaces to enjoy. Richmond Park, Terrace Gardens and the riverside at Twickenham are all popular choices on days like this, and are generally busiest in the early afternoon.
If you are heading out, the NHS advises staying hydrated, avoiding the midday sun between 11am and 3pm, and checking on older neighbours or relatives who may struggle in the heat. The overnight low of 17°C means homes can stay warm into the evening, so keeping curtains closed on south-facing rooms during the day helps.
