Explore historical and projected climate data, climate data by sector, impacts, key vulnerabilities and what adaptation measures are being taken. Explore the overview for a general context of how climate change is affecting Croatia.

Impacts Water

Climate change will impact Croatia’s water supply, impacting demand from the agricultural sector as well as increasing drinking requirements. Annual distribution of rainfall is of great interest to the water industry as the distribution of water throughout the year is critical for planning of resources as well as for safeguarding against disasters. Infrastructure and water management strategies are closely tuned to the annual cycle of supply and demand. The Mediterranean, including the Croatian Adriatic coastline, is affected by global sea-level rises. Particularly at-risk areas from sea level rise are low islands such as Krapanj (only 1.5 m above sea level) and river deltas (i.e. the Nereteva river delta), which also includes large areas of agricultural land vulnerable to coastal flooding and salinization.

This section provides insights into projected climate change impacts on various hydrological indicators.


Data presented under Historical Climate Conditions are reanalysis products derived from ERA5-Land data. ERA5-Land is a global land-surface dataset at 9 km resolution, consistent with atmospheric data from the ERA5 reanalysis from 1950 onward. Climate reanalyses combine past observations with models to generate consistent time series of multiple climate variables. They provide a comprehensive description of the observed climate as it has evolved during recent decades, on 3D grids at sub-daily intervals. 

This data has been collected, aggregated and processed by the Climate Resilience Cluster of the European Space Agency’s (ESA) Earth Observation for Sustainable Development (EO4SD) initiative.
