Wet Tuesday ahead for Chiswick with showers and a high of 21°C
8 September 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
If you were hoping for a gentle early-September Tuesday, today is not quite that day. The Met Office is forecasting light rain showers across Chiswick throughout Tuesday 8 September, with an 80% chance of rain and the possibility of heavier downpours at points during the day.
Temperatures will reach a high of 21°C, so it will not feel cold, but an umbrella or a waterproof jacket is strongly advised before heading out — particularly for the school run, the morning commute, or any outdoor plans. The overnight low will drop to 13°C, making for a noticeably fresher evening.
The UV index is forecast at 4, classed as moderate, though cloud cover will limit direct sun exposure for most of the day. Those who left summer gardening equipment or garden furniture out over the weekend may want to bring it in or cover it up before the heavier spells arrive.
Full forecast details, including hour-by-hour breakdowns, are available via the Met Office forecast page.
