About Portsmouth
Portsmouth Weather
Overview
A seaside, island town, Portsmouth is subject to regular precipitation and wind gusts, so expect more than just ocean spray to be drenching your clothes. It's moderately warm from June until September, but still given to regular downpours. Overnight temperatures are less extreme than British towns further north and inland, but still quite chilly.
