Heavy rain expected today in Barnes, high of 24°C
19 August 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
After the recent hot spell, today brings a marked change in Barnes: the Met Office is forecasting cloudy skies, a high of 24°C and a 74% chance of rain, with heavy downpours likely at some point during the day. The low tonight is expected to drop to 16°C — a noticeable shift after the temperatures well above 30°C seen earlier this week.
The UV index is still rated at 6 (high), so if there are any dry spells, sun protection remains worth thinking about — particularly for anyone spending time outdoors with children during the summer holidays.
If you're heading out today, an umbrella and a light waterproof layer are sensible precautions. Gardeners in the area may welcome the rainfall after a dry and exceptionally warm August so far. Those with outdoor plans should keep an eye on the forecast through the day, as timing and intensity of the rain may shift. Full forecast details are available from the Met Office.
