A pleasant Saturday in Barnes: 23°C and sunshine, but UV is high
20 July 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
After the blistering heat of recent days, today brings a slightly more comfortable afternoon in Barnes — sunny skies, a high of 23°C and just a 1% chance of rain, according to the latest Met Office forecast. The overnight low is expected to be around 14°C, offering a cooler night than the borough has seen for much of this week.
One note of caution: the UV index is rated at 8, which sits in the very high band. Sunscreen, a hat and sunglasses are sensible precautions if you are spending time outdoors — particularly for children. The NHS recommends SPF 30 or above and reapplication every two hours when UV is this strong.
Conditions look well suited to Barnes Common, the Wetlands Centre or a walk along the towpath this afternoon. Cafés and pubs with outdoor seating are likely to be busy, so it may be worth arriving early or booking ahead if you have a specific spot in mind.
It is worth noting that SWR is running a special timetable today due to disruption elsewhere on the network, so if you are travelling by train check your journey before you leave.
