The heat steps up today: Barnes forecast to hit 36°C
13 August 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
After a run of hot days, today's forecast pushes the temperature higher still — the Met Office is predicting a high of 36°C in Barnes, up from the 32°C recorded earlier this week. Overnight the mercury will stay warm at around 22°C, so it may be a sticky night.
The UV index is rated at 7 (high), meaning sun protection is strongly advisable for anyone spending time outdoors, particularly between 11am and 3pm. The chance of rain is just 4%, so there's little prospect of relief from a passing shower.
Residents are advised to keep well hydrated and to check in on elderly or vulnerable neighbours who may struggle in the heat. Dogs and young children should not be left in parked cars. Barnes Pond and the Green can be pleasant spots to catch a breeze off the water, though shade is limited in the middle of the day.
The NHS recommends drawing curtains on sun-facing windows during the day and opening them at night to let cooler air circulate. Full forecast details are available from the Met Office.
