Water Temperature: Daily Trends, Historical Records, and Forecast
❌ As of today, the minimum water temperature ranges from 50°F (10°C) to 54°F (12°C). The water is slightly warmer, but still cool for most people. Swimming in such conditions is possible, but for most people, the time spent in the water should be limited to avoid hypothermia. Even experienced swimmers may feel discomfort if they stay in the water for too long. To improve comfort and safety, a wetsuit can be used. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

*** 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
Kaunas (in Lithuanian — Kaunas) lies where the Nemunas and Neris rivers meet and is dominated by the Kaunas Reservoir, an impounded lake commonly used for recreation. Water temperatures vary strongly by season: in spring waters typically rise from about 2–8 °C (36–46 °F) in March–April to 8–15 °C (46–59 °F) in May. Summer brings the warmest conditions, usually 18–25 °C (64–77 °F) from June through August and occasionally reaching 26–27 °C (79–81 °F) during heatwaves. In autumn temperatures fall to roughly 10–18 °C (50–64 °F) in September and drop toward 2–10 °C (36–50 °F) by October–November, while winter waters hover close to freezing, roughly 0–4 °C (32–39 °F) before ice forms.
Swimming is permitted in Kaunas at designated beaches and city-managed waterfronts where water quality is monitored, and many locals and visitors swim in summer when temperatures are comfortable. Safety considerations influence access: strong currents in some areas, boat traffic on the reservoir and occasional algal blooms mean swimming is recommended only in marked, supervised zones. Ice swimming is practiced by enthusiasts in winter but requires proper local guidance and rescue provisions; casual bathing is discouraged when temperatures are near freezing or when authorities advise against entering the water.
