Poland Sea Temperature in August

Historical 30-year sea surface temperatures across 9 coastlines in Poland for August. Derived from NOAA 0.25° blended satellite and in-situ marine observations.

Notice: 30-year historical climatological monthly mean (1991–2020), not a live single-day sensor forecast.

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)
