Sunny late-summer Tuesday ahead — highs of 25°C in Chiswick
25 August 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
A proper end-of-August day is forecast for Chiswick today, with unbroken sunshine, a high of 25°C and only a five per cent chance of rain — welcome news after recent unsettled spells.
The UV index is rated at 6, which the Met Office classes as high, so sun cream is worth applying if you are spending a good chunk of the day outside. The overnight low will be a comfortable 18°C, meaning this evening should stay warm well into the night.
With the Bank Holiday weekend only days away, today is a good opportunity to make the most of Chiswick's outdoor spaces — Chiswick House and Gardens, the riverside walk between Strand on the Green and Kew Bridge, and the quieter stretches of the Thames Path are all pleasant in this kind of weather. The route along the river can also be a useful alternative to the Piccadilly, Mildmay and District lines, which are all experiencing disruption today.
The full forecast for the area is available via the Met Office website.
