A fine September Saturday: sunny skies and 23°C for Richmond today
12 September 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
After a mixed week, today shapes up to be one of the better days of the month — clear sunshine, a high of 23°C and only a 6% chance of rain, according to the Met Office forecast for Richmond.
The UV index sits at 5, which is moderate — enough to warrant sun cream if you're planning to be outside for a few hours. The overnight low will be a comfortable 18°C, so this evening should stay pleasantly warm well after dark.
With six-plus hours of sunshine expected, it's a good day to make the most of Richmond's outdoor spaces — whether that's the Terrace Gardens, the riverside path between Richmond and Twickenham, or a picnic on the Green. Richmond Park is always a reliable option on a day like this, though parking fills up quickly on sunny Saturdays, so arriving on foot or by bike is worth considering.
The forecast looks settled for the rest of today, so no need to plan around showers. Enjoy it — September days like this are worth savouring.
