The best time to visit Croatia is from June-August or September – October. Croatia has a mild climate throughout the year. The country is divided into two regions, inland and coastal. Historic centres in the coastal area, namely, Split, Dubrovnik and Zadar are great for sightseeing during mild winters. During the peak season, coastal Croatia is hot and ideal for sunbathing and swimming. September and October, on the contrary, are less crowded and the weather is pleasant too. From October till March, the coastal region is significantly quiet with a host of excellent accommodation options and hotels closed for tourists. Inland Croatia consists of places like Zagreb, Plitvice and Motovun, and these are better not experienced during the winter months.
The best time to visit inland Croatia, which is often termed as the most beautiful part of the country, is during autumn. During this time, the travellers can enjoy new wines and enjoy the picturesque natural beauty at the fullest. December is, however, the rainiest month in Croatia and hence, should be avoided by the tourists.
