A wet Sunday in Barnes: light rain and a high of 22°C
13 September 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
After yesterday's fine September sunshine, today brings a change of mood over Barnes. The Met Office is forecasting light rain throughout Sunday 13 September, with a 72 per cent chance of precipitation and the possibility of heavier downpours at times. Temperatures remain mild, with a high of 22°C and a low of 18°C overnight — so it stays warm even if it stays damp. The UV index is a modest 3, meaning sun cream is unlikely to be needed today.
If you had outdoor plans — a trip to the wetlands, a bike ride along the river, or a picnic on the Common — it is worth keeping an eye on conditions and dressing for the rain. A waterproof layer and sensible footwear will go a long way. The mild temperatures do at least make this the kind of grey day that is perfectly suited to a coffee and the papers somewhere warm indoors.
