Heavy rain for Barnes today — a wet end to August bank holiday weekend
29 August 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
Saturday brings a thoroughly soggy close to the bank holiday weekend, with the Met Office forecasting heavy rain across Barnes for most of today. Temperatures will reach a modest 20°C and drop no lower than 17°C overnight — not cold, but firmly mackintosh weather.
The chance of rain sits at 95%, so there is very little prospect of a dry window for outdoor plans. UV index is just 2, meaning sun protection is not a concern today. If you had garden parties, outdoor sport or a trip to the riverside in mind, it is worth rescheduling or moving inside.
The Thames towpath and Leg o' Mutton nature reserve can become slippery and muddy after heavy downpours, so walkers should take care on unpaved paths. Cyclists using the riverside routes are similarly advised to allow extra stopping distance.
