Weather locations in Croatia

Croatia sits between the Pannonian Plain, the Dinaric Alps and the Adriatic Sea, and that position gives it almost every European climate type except the polar one. Its interior is continental, its mountain belt is cool and wet, and its narrow coastal strip is Mediterranean, with hot dry summers and mild damp winters. The dividing line runs roughly along the mountain chain, so the country can hold three climate zones within a few tens of kilometres.

Main climate types

The mainland around Zagreb has a humid continental climate, classed Cfb, with four distinct seasons and cold winters. The Dinaric mountain belt through the middle of the country is cool and very wet, and the high karst plateaux of Gorski kotar take over 2,000 mm of precipitation a year, some of it as snow. The Adriatic coast, from Rijeka south to Dubrovnik, is Mediterranean, mild and wet in winter and hot and dry in summer, when August is often the driest month.

Temperatures

Zagreb runs from about 1 °C in January to about 23 °C in July, with occasional continental cold snaps in February. On the coast at Split, January means are about 10 °C and July about 26 °C, with the sea peaking near 26 °C in August. Stations above 1,000 metres average well below freezing in January and around 10 °C in July. Wind is part of the climate too: the bora, a cold north-easterly, can blow for days along the coast, especially from late autumn into winter.

Rainfall

Precipitation totals are higher than many visitors expect. Zagreb receives around 900 mm a year, roughly half of it in the cool half of the year, while the mountain interior gets twice that. Coastal stations sit near 800 to 1,000 mm, with a distinctly autumn-heavy distribution where moist air off the Adriatic meets the coastal mountains. Snow is normal inland and on the plateaux from December to February.

When to go

The coast is at its best in June, September and early October, when temperatures near 28 °C are offset by a sea breeze. July and August are hot. For mountain walking, July and August give the longest days and the snow season in the Gorski kotar runs from roughly January to March.
