Hot and sunny in Barnes today, with a high of 35°C
23 June 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
Tuesday looks set to be a scorcher in Barnes, with the Met Office forecasting a high of 35°C, clear sunshine and just a 5% chance of rain. The overnight low is expected to stay at around 25°C, meaning little relief even after dark. The UV index is rated 8 — classified as very high — so sun protection is strongly recommended, particularly for children, older residents and anyone spending time outdoors for extended periods.
Barnes Common, the riverside path along the Thames and the Wetland Centre gardens are all popular spots on hot days, but it is worth carrying water and seeking shade during peak afternoon heat, typically between noon and 3pm.
The NHS advises keeping homes cool by closing blinds and windows during the hottest part of the day, and checking in on elderly or vulnerable neighbours who may struggle in high temperatures. Barnes Library on Church Road is air-conditioned and open to anyone wanting a cooler environment.
The forecast is from the Met Office, updated in the early hours of Tuesday morning.
