Another hot day ahead in Chiswick — 31°C with a high UV index

Thursday brings more summer heat to Chiswick, with the Met Office forecasting a high of 31°C and a low overnight of 19°C. Skies will be partly cloudy through much of the day, with just a 5% chance of rain — so any cloud is unlikely to bring relief. The UV index is forecast at 8, which is rated very high, meaning unprotected skin can burn in as little as 15 minutes at peak hours. Met Office forecast

With temperatures staying well above 20°C overnight, it may be worth keeping windows on the shaded side of the house open after dark to help cool rooms down before morning.

Chiswick's green spaces — particularly Chiswick House and Gardens and the riverside paths along the Thames — offer some of the shadiest spots locally for those wanting to get outside without overdoing it in the midday heat. If you are heading out with children or elderly relatives, early morning or evening is strongly preferable to the 11am–3pm window when UV peaks.
