Warm and cloudy in Chiswick today — 28°C with the hot spell continuing
2 August 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
Sunday brings another warm day to Chiswick, with temperatures expected to reach 28°C and staying above 19°C overnight. The sky will be mostly cloudy, with just a 5% chance of rain — so while it will not be a classic sunny August afternoon, it will remain firmly summer weather. The UV index is forecast at 7, which is classed as high, so sun cream remains worthwhile whenever the cloud breaks. Met Office forecast for Chiswick.
The hot spell is forecast to continue into Tuesday at least, so this weekend's warmth is part of a broader settled pattern rather than a one-day anomaly. Chiswick's green spaces — Chiswick House grounds, Gunnersbury Park and the Thames towpath — are all well placed for getting outside without straying far.
For those planning outdoor activities today, the cloud cover may actually make conditions more comfortable than yesterday's brighter heat, and the negligible rain risk means plans should be safe to keep. Keep an eye on the Met Office app if you are out for the day.
