Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.
Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.
Water temperature data for this location is gathered from various sources, including buoys and satellite sea and ocean surface maps provided by the NOAA agency. We also incorporate data from local authorities in each specific location worldwide to ensure more accurate temperature readings.
Annual Water Temperature Overview by Month
Monthly Water Temp Ranges
Annual Water Temperature Trend
Gdańsk sits on the southern shore of the Baltic Sea and experiences a marked seasonal variation in sea temperature. In winter months (December–February) surface temperatures are typically around 0–4°C, and may approach freezing on colder winters, while early spring (March–April) usually sees waters of about 2–8°C as the sea slowly warms. By late spring and May the surface can reach 8–12°C, and the warmest period comes in June through August when typical values range from 14–20°C, with occasional heat spells pushing localized readings to around 22°C. Autumn (September–November) brings cooling waters, commonly 6–14°C, so the bathing season in the open sea is relatively short compared with more southerly coasts. The Baltic here is brackish and shallow in many spots, which makes temperatures vary quickly with weather and wind conditions.

Swimming Conditions
Swimming and beach holiday options reflect those seasonal limits and local infrastructure. Sandy beaches near the city — including popular stretches at Brzeźno, Jelitkowo and Stogi — offer lifeguard services and designated bathing zones during the summer months when water is most comfortable for swimming; outside of July and August, many visitors find the sea chilly and opt for quick dips, wetsuits, or alternative activities. Kayaking, paddleboarding and open‑water swimming groups operate in calmer weather, and indoor pools and aquaparks provide year‑round swimming for families and training. Anyone planning sea swimming should be mindful of variable currents, weather changes and the typically lower Baltic temperatures, and prepare accordingly if venturing into water below about 16°C for extended periods.
