Saturday looks glorious in Barnes: 28°C and almost no chance of rain
8 August 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
After a week that has already delivered some notable heat, Saturday is shaping up to be another fine day in Barnes. The Met Office is forecasting a high of 28°C and a low of 19°C overnight, with a UV index of 7 — high enough to warrant sunscreen if you're spending any length of time outdoors — and just a 5% chance of rain. Forecast via the Met Office.
It is worth noting that cloudy periods are expected alongside the warmth, so it may not feel as relentlessly sunny as earlier in the week, but conditions should remain comfortable and largely dry throughout the day.
The fine spell is forecast to hold well beyond the weekend — the Met Office suggests settled weather for a week or more, which is welcome news for anyone with plans on the river, in Barnes's parks, or at one of the outdoor tables that have been doing brisk trade along Church Road and the High Street.
UV index 7 counts as high: the NHS recommends SPF 30 or above, sunglasses, and shade during the middle of the day for fair-skinned residents. A warm Saturday evening should make for a pleasant end to the day.
