Understanding Brighton's Weather

Brighton has a maritime climate with mild winters and warm summers. As a coastal city, temperatures tend to be moderated by the sea — cooler than inland in summer and warmer in winter. Expect more wind than inland areas, especially along the seafront.

Average annual rainfall is around 750mm, lower than the UK average. The sunniest months are May to August. Brighton is one of the sunniest cities in the UK, with over 1,700 hours of sunshine per year.

The UV index can reach 7–8 in summer — sunscreen is recommended for beach days from April to September. Coastal fog ("sea fret") is common in spring and early summer when warm air meets cold sea water.
