Another warm one today: 26°C in Barnes with low rain risk
3 July 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
Thursday is shaping up to be a pleasant summer day in Barnes, with the Met Office forecasting a high of 26°C and a low of 16°C overnight. Cloud cover will be partial through the day, so expect a good mix of sun and shade rather than wall-to-wall blue sky.
The chance of rain sits at just 5%, so there is little need to carry a brolly, though UV index 9 is classed as very high — sunscreen is well worth applying if you are planning time outdoors, particularly around midday.
The riverside path, Barnes Common and Wetland Centre all come into their own on days like this. The Leg o' Mutton reservoir near the Wetland Centre is also worth a visit if you have not been recently, and the Common's open grassland tends to be quieter than the more formal parks.
Do bear in mind that barbecues remain banned in Richmond parks and on the Common throughout the summer period. The full Met Office forecast is available here.
