Portsmouth residents should prepare for a shift from sunshine to rain as a damp and cloudy outlook is forecast for the weekend starting 7 March 2026. The Met Office expects a bright start to Thursday in Hampshire before conditions turn grey and wet.
Thursday, 5 March 2026, is expected to be the best day for outdoor tasks with dry, mild, and bright weather. Temperatures are set to reach a high of 17°C with plenty of hazy sunshine throughout the afternoon once early morning mist and fog clear.
The weather will start to turn on Friday, 6 March 2026, as the city becomes cloudier during the morning hours. Light rain is forecast to arrive in the afternoon and is likely to become heavier and more persistent by the evening.
The outlook for the weekend and into Monday, 9 March 2026, includes persistent low cloud and patches of fog. The Met Office predicts that further rain will occur at times, keeping conditions damp across the region.
Drivers using exposed or low-lying roads managed by Portsmouth City Council should be aware of possible minor travel delays. While no official weather warnings are in place, the combination of fog and wet surfaces may make travel more difficult than usual.
