Residents in Slough can look forward to a warm and settled week ahead, as a high-pressure system brings sunny conditions to the area between 22 and 28 April 2026. Following a cold and frosty start to the week, where temperatures dipped to near-freezing, the Met Office expects a steady climb in temperatures.
Daytime highs are forecast to reach 17°C by Wednesday, continuing to rise throughout the week until hitting a peak of 21°C this Saturday. With a large area of high pressure situated to the north of the UK, the region will remain dry with a less than 5% chance of rain for most of the period.
While the dry and sunny weather offers a pleasant change, the conditions are also expected to trigger high pollen levels. The Met Office reports that the warm, dry air makes it easier for pollen to be released and carried by the wind. Birch pollen is expected at high levels, while oak pollen is at moderate levels, with the oak season currently starting.
The Met Office also advises that UV levels will be moderate throughout the week. Residents are encouraged to use sunscreen and take extra care if spending time outdoors during the middle of the day.
