Slough, Berkshire, is expected to experience a brief spell of warmer weather during the weekend of February 21, 2026, with temperatures reaching 14C.
The Met Office predicts daytime highs will remain at 14C on both Saturday and Sunday. This forecast is much higher than the typical February average of 8C and comes after a cold week where temperatures fell as low as -2C.
Although the weather will be milder, residents should expect overcast skies with a 20 per cent chance of light rain. The warmer air is expected to make outdoor activities more comfortable and may increase the number of people visiting local parks.
Local gardeners may find the weekend suitable for winter tidy-ups and pruning. These milder temperatures provide an opportunity for early-season tasks such as planting dahlia tubers or preparing soil for the coming spring.
This milder period follows a cold start to the month, including a chilly Valentine’s Day on February 14, 2026. While the weekend will be warm, the weather service noted that frost is still possible during the nights before the temperature rise begins.
