May is the best all-round month for a Hull holiday—sunshine hours are usually longer than in the June-to-August high season, and rainfall is lower. Swimmers like the seawater temperatures of late August and September, which are the year’s balmiest. May and September are the best hiking months in the wolds, when average daily temperatures hit 16-19°C. Big Hull-area festivals include The Awakening arts celebration in March, August’s Tribfest in Driffield, and the Flamborough Fire Festival in December.
