Sunny and 25°C in Chiswick today — fine spell set to last the week
7 August 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
After a week of mixed conditions, Chiswick is waking up to a genuinely settled spell of summer weather. The Met Office forecast for today is sunny throughout, with a high of 25°C and a low of 17°C overnight. There is zero chance of rain, and the UV index reaches 8 — firmly in the 'very high' band — so sun cream is worth remembering if you're spending time outside.
The good news extends well beyond today: the fine spell is forecast to hold for at least another week, which bodes well for the remainder of the school holidays. Chiswick's parks, the riverside at Strand-on-the-Green, and the outdoor tables along the High Road should all come into their own over the coming days.
UV index 8 means that unprotected skin can burn in as little as 15–20 minutes, particularly between 11am and 3pm. The NHS recommends SPF 30 or above and keeping children shaded during peak hours.
