Chiswick bakes at 32°C today — hot sunny spell continues through Friday
12 August 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
Tuesday is shaping up to be the hottest day of the summer so far in Chiswick, with the Met Office forecasting a high of 32°C, clear sunshine and barely a cloud in sight. The overnight low is 21°C, so even evenings will feel warm. The UV index is at 7 — classed as high — meaning sun protection is genuinely recommended for anyone spending time outside, particularly during the midday hours. The full forecast is available from the Met Office.
The good news is there is almost no chance of rain (1%), so Chiswick's parks, riverside and outdoor cafés should be in fine form. The hot spell is forecast to hold through Friday, giving residents several days of summer weather to enjoy.
A few practical notes for the heat: Dukes Meadows and the Thames Path both offer shade along the river, and the outdoor lido at nearby venues can get busy on days like this — worth booking ahead if you can. Stay hydrated, keep an eye on younger children and elderly neighbours, and avoid strenuous exercise in the hottest part of the afternoon.
