Hot but unsettled today in Richmond, with a 32°C high and storm risk
27 June 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
After a week of relentless heat, today brings a more complicated picture: the Met Office is forecasting a high of 32°C for Richmond, but with a 59% chance of rain and the possibility of storms developing later. The overnight low will stay unusually warm at 20°C, meaning little relief even after dark.
The UV index is forecast at 8 — classed as very high — so sun cream, hats and shade remain important even if the sky looks grey for stretches of the day. UV rays penetrate cloud cover more effectively than most people expect, so protection is still worthwhile.
Anyone planning to spend time in the parks or by the river should keep an eye on conditions through the afternoon, when thunderstorms are most likely to develop during hot, humid spells. The Thames towpath and open parkland are exposed when lightning is about.
If you have plans that depend on the weather — a picnic, a cycle ride, a trip to the outdoor pool — it is worth checking the Met Office forecast before you head out and building in some flexibility. A change of plans mid-afternoon is more likely today than it has been for much of this week.
