Croatia has significant differences in climate due to its geographical location. Along the coast of Dalmatia and Istria, the climate is tempered by the influence of the Adriatic Sea and is mainly Mediterranean, with mild winters and hot, dry summers.
The mountains of the Dinaric Alps act as a barrier to the mild influence of the sea, and in areas east of the mountains, ie in the hilly areas and plains of Slavonia, in the area of the capital Zagreb and along the rivers Sava, Drava and the Danube, the climate is continental with cold and snowy winters, and hot summers.
In the inland areas there are average minimum temperatures below freezing during the winter months between December and February, this area is also characterized by the blowing of strong winds, including during the winter, the famous Bora. In this area the wettest periods are the summer and autumn months.
The mountains receive the highest quantity of precipitation. Along the Dalmatian coast and Istria the climate is Mediterranean with mild temperatures and heavier rainfall in the winter months, in the Dalmatian islands and the southern coast of the country there are the maximum values of insolation, the island of Hvar (Lesina) has an average annual of 2674 hours of sunshine.
The temperatures of the places of Croatia depend on their position with respect to the mountains and exposure to winds, temperatures increase proceeding from west to east and from north-west to north-east.
The coldest month is January with an average temperature of -2°C inland to 5°C in the coastal regions. The hottest month is July with an average temperature of 15°C inland and 24°C in the coastal regions. In some areas of the interior plains sometimes during the summer, there are values higher than 30-35°C.
