Hot and cloudy today in Barnes, with temperatures reaching 28°C
5 July 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
After a string of warm days, Sunday brings another notable high to SW13 — 28°C according to the latest Met Office forecast, making it the warmest day of the recent spell so far.
The sky will stay largely cloudy through the day, so the heat may feel less fierce than the temperature suggests, but the UV index is forecast at 8 — rated very high — meaning sun protection is still strongly advisable, particularly for children and anyone spending extended time outside. The chance of rain is just 5%, so outdoor plans are unlikely to be disrupted.
The overnight low sits at 18°C, so it will remain warm well into the evening — good news for anyone with garden plans or a walk along the river towpath after dinner.
A UV index of 8 means that unprotected skin can burn in as little as 15 minutes, even under cloud cover. The NHS recommends SPF 30 or higher, sunglasses and staying in the shade between 11am and 3pm. Full forecast from the Met Office.
