Traveller notes on Bournemouth in August
August in Bournemouth is the peak of everything. A good day can reach the mid-to-high 20s°C, though the monthly average high sits nearer 21, with the sea around 17°C. The forum's real subject, though, is volume: a very hot summer's day brings roughly 80,000 people to the beach, and an airshow day upwards of 250,000. Regulars advise avoiding the Pier area for crowding and parking and heading to Southbourne, Christchurch and Hengistbury Head, or Mudeford instead. Two August fixtures worth timing around: fireworks off the pier every Friday night from late July to the end of August, and the Wednesday candlelight evenings in the lower gardens.
