Residents in Portsmouth can look forward to a week of dry and sunny weather, with temperatures expected to remain slightly higher than usual for late April. According to the Met Office, the UK’s national meteorological service, this settled period is set to continue from Friday, 24 April through Thursday, 30 April 2026.
Daytime temperatures will range between 17°C and 19°C throughout the week. While the afternoons will be pleasant, residents should be prepared for cooler evenings, as night-time temperatures are forecast to drop to around 5°C. Those planning to be out after sunset may want to bring a light jacket.
The Met Office indicates that the dry conditions are supported by a dominant high-pressure system across parts of the UK. With the chance of rain remaining below 5% through Sunday, it is an ideal time for outdoor activities, although those heading out during midday hours should be mindful that UV levels will be moderate and using sunscreen is advised.
Those who suffer from hay fever should note that pollen levels for oak are forecast to be high across the region from Friday through Tuesday. However, air pollution levels are expected to remain low throughout the entire period. Winds will stay light, generally blowing from the east and east-northeast, with maximum gusts expected to range between 18mph and 32mph.
