Hot again in Barnes today — 30°C, some cloud, very high UV
14 July 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
Monday brings another hot day to Barnes, with temperatures expected to reach 30°C this afternoon — almost identical to Friday's peak but arriving with more cloud cover. The overnight low was around 19°C, so it will already feel warm first thing.
The UV index is rated 8, which is classified as very high. That means meaningful sun protection is advisable even on a partly cloudy day: UV reaches the ground through thin cloud, and conditions like these can catch people out. Keep sunscreen handy if you are spending time outdoors — at the pond, on the Green or along the riverside path.
The chance of rain sits at just 9%, so outdoor plans should be fine, but the cloud cover may make it feel a little more oppressive than recent sunny days. Shade will be welcome by mid-afternoon.
With the heatwave of recent days still fresh, it is worth continuing to check on elderly or vulnerable neighbours who may be struggling with the sustained warmth. Staying hydrated and keeping out of direct sun between roughly 11am and 3pm remains sensible advice.
