Another fine day in Richmond — 28°C, UV index 8, almost no rain
16 July 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
Thursday is shaping up to be another warm, sunny day in Richmond, with the Met Office forecasting a high of 28°C, a low of 16°C overnight, and just a 1 per cent chance of rain. The UV index reaches 8 — classified as very high — so sun cream, sunglasses and shade during the midday hours are genuinely worthwhile rather than optional.
After a run of notably hot days in the borough this week, today sits at the more comfortable end of the recent spell — warm enough to make the most of Richmond's parks and riverside, without the intensity of last week's 34°C peak.
A UV index of 8 means unprotected skin can begin to burn in as little as 15 minutes for fair-skinned people. The NHS recommends SPF 30 or above, and the British Red Cross advises keeping an eye on anyone elderly or very young in prolonged heat.
If you're heading to one of the borough's parks, it's also worth noting the newly installed defibrillators at Old Deer Park — part of a wider roll-out covered separately today. Richmond's outdoor lidos and splash areas are open; check individual venues for current hours.
