Sunny Tuesday ahead for Barnes with a high of 24°C
22 September 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
September is going out in style over Barnes today. The Met Office is forecasting a fully sunny day with temperatures climbing to 24°C this afternoon — a step up from the 21°C that has characterised the recent fine spell — before dropping back to a comfortable 16°C overnight.
The chance of rain is negligible at just 1%, and the UV index sits at 4 (moderate), so a light sunscreen is worth applying if you are spending a prolonged stretch outside. It is still warm enough to make the most of the river path, Barnes Common, or a pavement table at one of the high street cafés.
For those heading into central London, lighter clothing should be fine for the commute, though an extra layer in a bag is sensible for the journey home once the sun dips. Sunset this evening falls around 7.20pm, giving a good few hours of usable light after the working day.
The fine conditions look settled through today at least. Full forecast details are available via the Met Office.
