Where to go: the southern coast has the edge

Dubrovnik, Cavtat and Split are the better choices if warmth matters: all average 20°C by day, compared with 18°C in Pula. Cavtat has a slight advantage on rain, with 10 rainy days against 11 in Dubrovnik and Split, though that is not enough to promise a dry stay. For swimming, Dubrovnik and Cavtat also have the warmer sea at 21°C, while Split and Pula average 20°C. Pula still suits travellers happy with cooler daytime conditions, but its 13 rainy days make flexible plans especially useful. The differences are modest, so choose the south for the weather advantage without expecting a different season.

What to expect: comfortable days, layers and rain cover

Pack for mild weather rather than dependable beach heat. With 5.6 hours of sunshine on average, there is scope for time outside, but sunshine is not an all-day promise. Light clothing can work during warmer spells; bring a jumper and waterproof jacket for cooler or wet periods. Evenings need more thought than afternoons, especially in Split, where nights average 13°C. Sea temperatures make a dip plausible for travellers comfortable with cooler water, but they do not guarantee comfortable lounging afterwards. Keep outdoor plans movable and leave room for sheltered breaks. October works best when a swim is a bonus and a wet day will not spoil the trip.
