22 July 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
Tuesday brings a warm but overcast day to Barnes, with the Met Office forecasting a high of 27°C and a low of 18°C overnight. Cloud cover is expected to dominate throughout the day, keeping conditions muggier than the bright sunshine of recent days, though the chance of rain remains very low at just five per cent.
One thing to be aware of despite the cloud: the UV index is forecast at 7, which is classed as high. Cloud does not block UV to the degree many people assume, so sun cream remains worthwhile if you are spending time outdoors — particularly on Barnes Common, by the river, or at any of the outdoor events taking place across the borough this week.
Temperatures should remain comfortable through the evening, making it a reasonable night for dining outside at one of the restaurants along the High Street or Church Road. Carry a light layer if you plan to be out late, as the overnight low of 18°C is a meaningful drop from the daytime peak.
