Heavy rain expected in Richmond today — keep an umbrella to hand
30 September 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
Wednesday brings a mixed bag for Richmond. The Met Office is forecasting a high of 23°C — pleasantly mild for the last day of September — but an 84% chance of rain and the prospect of heavy downpours means it is very much a coat-and-umbrella day.
The low tonight is expected to drop to 13°C, so layering up is sensible if you are heading out for the evening. The UV index is a modest 3, so sun protection is not a priority today.
For anyone with outdoor plans — school runs, a lunchtime walk along the Thames Path, or an al fresco lunch — it is worth keeping a close eye on the timing of the heaviest showers. The Met Office hourly forecast will give the clearest picture of when the worst rain is likely to arrive.
Drivers should be aware that surface water can build up quickly on some of Richmond's lower-lying streets and riverside paths during heavy rain. Pedestrians near the river may also want to check current Thames water levels before heading out.
