21 July 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
A fine Sunday is on the cards for Barnes, with the Met Office forecasting a high of 25°C and largely sunny skies breaking into patches of cloud through the afternoon. The overnight low sits at 18°C, so it should remain comfortable well into the evening.
The UV index is forecast at 7 — classed as high — so sunscreen is well worth applying if you're spending time outside, particularly with children. The chance of rain is just 4%, making it as reliable a summer day as you're likely to get.
It is the kind of afternoon that suits Barnes Pond, the riverside path along the Thames, or a picnic on Barnes Common. The terrace at the Bull or a table outside one of the Church Road cafés will likely fill up early. With school holidays in full swing, the green spaces are expected to be busy from mid-morning.
The Met Office forecast shows the fine spell is set to continue into the evening, so there's no particular rush to pack up early.
