Residents in Southampton can expect a dry and warming week as temperatures rise across the city between 20 April and 26 April 2026. According to the Met Office, daytime highs will climb steadily from 15°C on Monday to reach a peak of 20°C by Thursday.
This temperature range is well above the typical April average of 13°C for the area. While conditions remain settled and dry throughout the week, residents should prepare for a windy Wednesday, 22 April, with gusts expected to reach 34mph.
The Met Office has issued a reminder that UV levels will be moderate throughout the week, and sunscreen is advised for those spending time outdoors during midday hours. Additionally, those with allergies should be aware that pollen levels are currently forecast as moderate to high, driven by birch pollen and the onset of the oak season.
This period of warm weather follows a trend of unusually high temperatures across the UK this spring. While the country saw its first 20°C day of the year back on 18 March, and some areas experienced temperatures as high as 26.6°C earlier this month, the current forecast for Southampton remains in line with historical patterns for late April.
