Portsmouth’s weather today, as shown in the live forecast above, is typical of the south coast: changeable with a mix of cloud and bright spells and a moderate breeze off the Solent. Temperatures will feel mild for the season, but keep a light jacket handy for any showers.
What’s the outlook for the rest of the week in Portsmouth?
The pattern remains unsettled through midweek, with the best of any drier interludes on Wednesday afternoon. The Met Office weather for Portsmouth points to a low-pressure system drifting across the English Channel, bringing occasional rain and fresh south-westerly winds. Night-times will be near average, and by Friday a brief ridge of high pressure should bring more settled conditions for the weekend.
Will it be windy along the coast?
Yes, especially on Tuesday and Thursday when gusts may reach 35–40 mph along exposed seafronts. The wind will ease a little by Friday, but the Solent always funnels a breeze, so if you’re heading to Southsea or the Spinnaker Tower area, it’s worth securing loose belongings. Check the live forecast above for hourly wind speeds.
What is the weather in Portsmouth tomorrow?
The live forecast above shows the detail, but briefly tomorrow will start cloudy with rain arriving from the west by midday, clearing to brighter skies later. Temperatures will be near normal for the time of year.
