Fine and warm in Barnes today, with highs of 25°C into Thursday
27 July 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
After a run of grey and humid days, Barnes is in for a proper fine spell — and it looks set to last. Today's Met Office forecast puts the high at 25°C, the low at 16°C overnight, and just a 10% chance of rain. The UV index sits at 7, so sun cream is worth digging out if you're spending time outside.
Crucially, the fine weather is expected to hold through Thursday, giving residents several days of reliable warmth. That makes it a good window for the riverside path along the Thames towpath, a session in Barn Elms, or a lunch outside one of the high street terraces.
With a UV index of 7 — classified as "high" — the NHS recommends keeping out of the midday sun between 11am and 3pm if you burn easily, and staying hydrated in the heat. Shade is plentiful in Barnes's tree-lined streets and along the waterfront.
The forecast is broadly consistent with the settled pattern that has dominated the South East through late July. Full forecast details are available from the Met Office.
