Southampton, Hampshire is set to experience heavy rain and a sharp drop in temperatures as a yellow weather warning comes into effect on 12 March 2026. The Met Office warns that this rain could lead to localised flooding and travel disruption across the city through the end of the week.
Following the passage of the rain, the recent mild conditions will be replaced by a much colder and windier state. This change in the weather is expected to last until 16 March 2026, which may lead to higher heating costs for households and a need to protect garden plants.
On Friday, 13 March 2026, the city will see a mix of sunshine and blustery showers that could turn wintry over higher ground. A widespread frost is also expected to develop by Saturday morning, potentially creating icy patches on local roads and footpaths.
