Residents in Slough can look forward to a warm and sunny start to the week, though hay fever sufferers are being advised to take precautions as pollen levels climb.
According to the Met Office, the weather in Slough will shift from an overcast Saturday with a high of 16°C and a cooler, unsettled Sunday to a period of warmer, dry conditions. Temperatures are set to rise, reaching 21°C on Wednesday, 8 April 2026. This forecast is significantly higher than the typical April average for southern England, which usually sees daily highs of around 12°C.
While the sunshine will be welcome, the Met Office has warned that pollen levels across the region will be very high from Sunday through to Wednesday. With high levels of both birch and ash pollen recorded, those who suffer from hay fever may notice an increase in symptoms. According to Allergy UK, birch pollen affects approximately one in four people in the UK who suffer from hay fever, with the current high levels being driven by the dry, sunny, and mild spring weather.
The warm spell is expected to be brief. Cloudier conditions are forecast to return by Thursday, along with a possibility of rain. Forecasters have noted a 30 per cent chance of rain at 10am on Thursday, followed by a 40 per cent chance of rain at 4pm on Friday.
Looking further ahead, the long-range forecast for 8 April through 17 April suggests that temperatures will likely remain around or slightly above average for the time of year, with the possibility of further short-lived warm spells across the south and east.
