Check the live forecast above for the most accurate picture, but Split’s Mediterranean climate means you can expect hot, dry summers and mild, wet winters — the key split is between the sunny coast and the cooler, rainier conditions inland during winter.
What makes Split’s weather different from the UK?
Split sits on the Dalmatian coast, sheltered by the Dinaric Alps. This brings far more sunshine and higher summer temperatures than you’d get at home. Winters are milder too — frost is rare — though rain is frequent between October and March. The Adriatic Sea moderates things, keeping the coast cooler in summer and warmer in winter than the interior. If you’re comparing conditions with the UK weather hub, expect longer, more reliable summers here.
When should you plan a trip to Split?
June to September delivers the most consistent heat and sunshine for beach days and island hopping. May and October are quieter, with pleasant temperatures for exploring Diocletian’s Palace and the surrounding coastline without the peak crowds. Winter is mild but damp, and many coastal hotels and ferry routes operate on reduced schedules. For a detailed outlook, check the 10 day weather forecast before you book.
Does Split get a lot of rain?
Yes, particularly between October and March. Split receives around 800 mm of rain annually, most of it falling in autumn and winter. Summers are very dry, with July and August seeing very little rainfall.
Is Split windy?
Yes, at times. The bora wind can bring strong, cold gusts from the interior, especially in winter. The jugo wind, from the south, often brings warmer, damp air and rain. Summer breezes are generally light and pleasant.
When is the sea warm enough to swim?
The Adriatic Sea around Split is usually comfortable for swimming from June through September. July and August see the warmest sea temperatures. In May and October, only the hardiest swimmers tend to go in.
