Residents in Southampton can expect a shift in weather this week as the windy conditions caused by Storm Dave give way to a spell of warm and settled conditions. According to the Met Office, the city is set to see temperatures climb significantly above the typical April average of 13 to 14 degrees Celsius.
The week will begin on a chilly note this coming Monday, 6 April 2026, with overnight temperatures dropping to 3 degrees Celsius and the potential for a light frost. However, conditions will warm up rapidly as the week progresses. Forecasters expect Tuesday, 7 April 2026, to reach 19 degrees Celsius, with the temperature peaking at 20 degrees Celsius on Wednesday, 8 April 2026.
While the sunshine will be a welcome change after the weekend’s windy weather, those who suffer from hay fever should prepare accordingly. The pollen forecast predicts very high levels across the area from Sunday through to Wednesday. It is estimated that approximately 13 million people in the UK suffer from hay fever, with tree pollen levels for alder, birch, and ash typically at their highest during March and April.
This warm trend will be short-lived, as the outlook indicates that conditions will turn cloudier and cooler from Thursday, 9 April 2026, onwards. By Friday, 10 April 2026, temperatures are expected to drop back to 14 degrees Celsius, with a risk of rain.
