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 Reservoir (Kauno marios) has a clear seasonal pattern in surface water temperature. In spring the surface typically warms from near freezing in March to roughly 4–12 °C (39–54 °F) by late spring. Summer brings the warmest conditions, with common daytime surface temperatures of about 16–24 °C (61–75 °F) and occasional local spots reaching the mid‑20s °C (upper 70s °F) during heat waves. In autumn the water cools again, generally falling through 10–16 °C (50–61 °F) in September and into single digits by November. Winter usually produces ice cover on much of the reservoir and water just above 0 °C (32 °F) beneath the ice; pockets of flowing water near the dam remain colder but unfrozen.
Swimming in Kaunas Reservoir is allowed in designated recreational areas and municipal beaches, where conditions are monitored and safety measures such as signage and occasional lifeguards are provided in the bathing season. Open‑water swimming outside marked zones, close to boat traffic, or near the hydroelectric dam is discouraged or prohibited because of currents, underwater structures and boating hazards. Water quality can vary and algal blooms sometimes occur, so swimmers should heed local advisories; winter ice‑swimming is practiced by some but requires proper safety precautions and local permission.
