Bournemouth enjoys one of the mildest and sunniest climates in the UK, sheltered by its south-facing position on the Dorset coast. It regularly tops the national sunshine charts, which is a big part of why the town has drawn holidaymakers for generations.

A gentle microclimate

Warmed by the sea and protected from the worst of the weather, Bournemouth sees milder winters and warmer summers than much of inland Britain. Frost and snow are rare on the coast, and the town basks in long, bright days through the summer months.

Summer temperatures

From June to August, daytime highs typically sit in the low-to-mid twenties Celsius, occasionally climbing higher during a heatwave. Sea breezes keep the beaches comfortable even on the hottest days.

Sea temperatures

The water is at its warmest from late July through September, usually peaking around 18–19°C brisk but very swimmable, especially with a little acclimatising. Spring and early summer swims are bracing, so many visitors bring a wetsuit.

What to pack

Even in high summer, pack a light layer for cooler evenings by the sea and always bring sun cream the reflected light off the sand and water is stronger than it feels. In spring and autumn, add a waterproof and comfortable shoes for coastal walks. Winter calls for a warm coat and hat for those invigorating beach strolls.
