Portsmouth, Hampshire, will see temperatures rise to a mild 13°C this weekend after a mid-week storm brings heavy rain and sleet to the city. The warmer shift follows a period of unsettled weather that is expected to peak on Wednesday, February 18, 2026.
According to the Met Office, Wednesday will bring heavy rain and wind gusts of up to 41mph. There is a 95 per cent chance of sleet showers starting around 9pm on Wednesday evening as temperatures drop near freezing overnight.
The weather will then turn significantly warmer on Saturday, February 21, and Sunday, February 22, 2026. Data from Weather Spark indicates that usual daytime highs for Portsmouth in February are around 8°C or 9°C, making the weekend forecast much warmer than the seasonal norm.
The milder conditions will provide a break from morning frosts for people attending outdoor heritage walks listed by Visit South East England. While temperatures will be higher, the sky is expected to stay overcast with occasional light rain and persistent coastal breezes.
Residents planning to attend events at the Portsmouth Guildhall or travel along the coast should still check for updates. The Met Office continues to monitor the Atlantic pressure systems that are causing these changeable conditions across the south coast.
