Croatia Sea Temperature by Month
12-month annual sea surface temperature curves across all 30 surveyed coastlines in Croatia. Data queried directly from NOAA OISST v2.1 1991–2020 0.25° grid climatology.
Notice: 30-year historical climatological monthly mean (1991–2020), not a live single-day sensor forecast.
Adriatic Karst Inflows & Island Archipelago Circulation
The eastern Adriatic coast features deep karst topography with submerged freshwater springs (vrulje) that discharge cold mountain runoff into select coves. However, protected channels between the Dalmatian islands (Hvar, Brač, Korčula) trap summer solar heat, yielding comfortable 24.5–25.0°C August bathing temperatures.
Oceanographic Phenomenon:
Subterranean Vrulja Springs & Island Shelter
Thermal Lag Characteristic:
Moderate Adriatic thermal lag: the shallow basin warms rapidly in June and cools faster in late autumn under the influence of cold northeasterly Bora winds.
Peak Bathing Average:
August (24.8°C)
