*** Forecast - Our water temperature forecast
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.

Location & Local Information
Alytus (in Lithuanian — Alytus) sits on the Nemunas and nearby reservoirs, offering freshwater swimming opportunities that vary with the seasons. Typical water temperatures in the area follow a clear seasonal pattern: in winter the surface is around 0 °C (32 °F) and often freezes, spring temperatures commonly rise from about 2–12 °C (36–54 °F) as ice melts, summer brings the warmest conditions with many years seeing 18–24 °C (64–75 °F) and occasional heatwaves pushing surface temperatures to 25–26 °C (77–79 °F), while autumn cools the water to roughly 8–15 °C (46–59 °F).
Swimming is generally allowed at designated beaches and recreational spots during the warmer months because local authorities monitor water quality and maintain safe bathing areas. Restrictions or closures can occur following heavy rains, pollution incidents, strong currents near dams or in river stretches, or when ice is present in winter; for safety reasons unsupervised or off‑season swimming is discouraged. Visitors and residents are advised to use marked bathing sites, heed posted warnings and local guidance about water quality and safety, since conditions can change with weather and river flow.
