Wet Tuesday ahead for Barnes: showers and a high of 20°C
8 September 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
After a warm weekend, Tuesday brings a change in the weather for Barnes. The Met Office is forecasting light rain showers throughout the day, with a notably high chance of rain at 83 per cent, and the possibility of heavier downpours at points. Temperatures will reach a high of 20°C and drop to around 12°C overnight — still mild for early September, but a jacket and umbrella are firmly recommended if you're heading out.
The UV index sits at 3, so sun protection is not a priority today. Parents doing the school run this morning, cyclists heading to Barnes station, and anyone planning outdoor lunch plans on the Green should factor in the conditions.
The wet spell is a reminder that summer is beginning to ease its grip, though 20°C remains comfortable enough for most outdoor activities if you're dressed for it. Keep an eye on the forecast through the week, as conditions can shift quickly at this time of year.
