How does Portsmouth’s coastal position affect its weather?

Being on Portsea Island, Portsmouth is heavily influenced by the Solent and Spithead. Sea breezes often moderate summer heatwaves, while in winter the surrounding water keeps frost less frequent than in nearby inland towns like Fareham. The city’s exposed southern flank can also see stronger winds during Atlantic depressions, so the UK weather hub is worth monitoring for any gale warnings.
