View 12-Month Annual Overview →Baltic Sea Extreme Seasonal Range
The Baltic Sea is a shallow, brackish semi-enclosed basin with low salinity (fed by large river basins) and restricted ocean exchange through the Danish Straits. This causes the widest annual water temperature swing in Europe: warming rapidly from 9.4°C in May to 18.6°C in August, then cooling quickly down to 2–4°C in winter.
Oceanographic Phenomenon:Brackish Semi-Enclosed Basin Dynamics
Thermal Lag Characteristic:Minimal deep thermal lag: the shallow brackish Baltic lacks deep-sea thermal inertia, causing water temperatures to drop precipitously by mid-September (14.5°C).
Peak Bathing Average:August (18.6°C)
