Weather in Croatia

The Republic of Croatia has a beautiful coastline, dotted with hundreds of islands, on the Adriatic Sea in central south-eastern Europe, south of Hungary. Its renowned walled medieval city, Dubrovnik, sits a little apart from the mother country in a southern piece of territory connected by territorial waters, a strip of Bosnia and Herzegovina inbetween.
The bulk of Croatia enjoys a typical continental climate, with warm to hot summers, very cold winters, and rain through most of the year. The coastal region and offshore islands have a Mediterranean Climate, with wet, chilly winters and warm, dry summers. The coast receives plenty of sunshine, particularly the outer islands of Hvar and Korcula, which are also the driest places in Croatia, while the wettest part of the country is the Dinara Mountains.
A unique feature of Croatia’s weather is the notorious “bura” – an unpredictable gale force gusty north-easterly wind that blows on the coast, usually in winter. The “bura” can cause problems for offshore sailors.
Most people who holiday in Croatia stay on the Dalmatian Coast during the summer months, which run from June to September. Days are long, sunny and pleasantly warm, the influence of the sea ensuring temperatures seldom exceed 30°C (85°F), and humidity is relatively low, making this ideal holiday beach weather. Dubrovnik is particularly dry, hot and sunny, with little to no rain during the summer season.
During the winter months (late October to early March) most of the beach resorts shut up shop, but the coastal urban centres of Split and Dubrovnik remain busy, despite being almost contantly wet with grey skies. The wettest month is November, and the coldest is January. Temperatures during winter on the Dalmatian Coast are mild, rarely descending to freezing, although the weather can be icy just a short distance inland. The outer Adriatic islands of Croatia, such as Hvar, Brac and Korcula, remain relatively dry and sunny even during the winter months, warm enough for sun-bathing.
The interior of Croatia – the central and northern parts of the country – are very cold in winter with the mercury often registering below freezing and heavy snow likely, allowing for Croatia skiing holidays. The country’s major ski resorts (Mount Sljeme, the Olympic Centre at Bjelolasica, and Platak) are all within easy reach of the centrally-lying capital city of Zagreb.
Summer in northern and central Croatia (with the exception of the high altitude area of the Dinara Mountains) is blisteringly hot, and dry, with temperatures regularly peaking in the mid to high 30s°C (80s to 90s °F).


When is the best time to go to Croatia?

The weather governs the best time of year to go to Croatia. For a beach holiday the best time is between June and August, although the resorts are crowded with holiday-makers and prices at their peak during the height of the season. Spring (April, May) and autumn (September, October) are pleasantly warm, sunny months on the coast and inland, ideal for sight-seeing or camping, but the sea will be a little chilly for bathing.
