Climate Data Historical

Croatia experiences a largely Mediterranean climate with hot, dry and sunny weather during the summer and relatively mild, yet rainy weather during the winter. Rainfall occurs throughout the year, with peak temperatures occurring June to September, and heavy rainfall in October to November. The majority of precipitation is recorded on the coastal slopes and peaks of the Dinarides to Gorski Kotar in the northwest, and to the southern Velebit in the southeast. The mountainous region and the coastal hinterland are mostly affected by drying tendencies in precipitation, especially during summer season, while the mainland is subjected to wetter precipitation conditions. In the Carpathian Region, heat wave events have become more frequent, longer, severe, and intense.


  • Mean annual temperature in the lowland areas of northern Croatia is 10-12°C.
  • The mountain regions experience mean annual temperatures of 3-4°C, with coastal areas at 12-17°C.
  • Analysis shows a general warming trend throughout Croatia, with higher temperatures experienced in the mainland in comparison to coastal areas.
  • Observed warming has been experienced in terms of both, warmer daytime temperatures and warmer nights.


  • Precipitation levels increase from October to December. The largest rainfall occurs in November (117mm).
  • Mountainous regions and the coastal hinterland are mostly affected by drying tendencies, especially during the summer season. The mainland is subjected to wetter conditions.
  • The fall in annual precipitation in the area north of the Sava River results from decline in spring and autumn precipitation. In the mountains and the Dalmatian islands, the fall results from decline in winter and spring precipitation.  Along the northern Adriatic, the reduction in precipitation is evident in all seasons.
