Residents in Southampton should prepare for a mix of sunny spells and scattered showers over the coming week, with the Met Office reporting variable conditions through to 22 April 2026. While daytime temperatures are expected to remain mild, ranging between 14°C and 17°C, the week will bring periods of unsettled weather.
The wettest period is expected in the early hours of Friday 17 April, with a 70% chance of rain forecast for 1am. Conditions are set to improve as the weekend approaches, with Sunday 19 April expected to be the driest day of the week. Forecasters anticipate a precipitation probability of less than 5% for most of Sunday, with only a slight increase to 10% in the afternoon.
Those who suffer from hay fever should remain cautious, as pollen levels are currently moderate and are expected to rise. According to the Met Office, birch and plane pollen are the primary contributors, with oak pollen also starting to emerge. Met Office Senior Scientist Lucy Neal noted that warm, dry, and sunny conditions can encourage trees to release more pollen, which may affect many residents.
There is currently no threat of flooding in the area. The Environment Agency confirms that there are no flood warnings or alerts in force for Southampton and that the flood risk for the next five days remains very low.
Looking further ahead to the end of the month, the forecast suggests a period of dry weather and sunny spells driven by high pressure. However, conditions may become unsettled again by the final weekend of April.
