Warm and cloudy today in Barnes, topping out around 31°C
7 July 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
Monday's forecast for Barnes is warm rather than bright, with cloud keeping conditions hazy despite a high of 31°C — almost identical to yesterday's peak. The overnight low was around 21°C, so it will already feel muggy by morning.
The UV index is forecast at 9, which is classed as very high, meaning the cloud cover will not offer much meaningful protection from sunburn. Sunscreen and staying in the shade during the middle of the day remain sensible precautions even when the sky looks grey. The chance of rain is just 5%, so the day should stay dry.
For those planning to use Barnes Common, the Wetlands or any of the riverside paths, the conditions are perfectly comfortable for walking or cycling, provided you dress for warmth rather than expecting a cool breeze. Carry water — 31°C is hot enough to cause dehydration more quickly than it might feel.
The Met Office forecast has the full picture for the coming days. The settled pattern looks likely to continue into the week, though overnight temperatures staying above 20°C can make sleeping difficult — worth opening windows early in the evening to let cooler air through before it warms again.
