*** 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
Lake Stirniai, like many small Lithuanian lakes, shows pronounced seasonal variation in surface water temperature. In spring (April–May) the surface typically warms from about 4–12 °C (39–54 °F) as ice melts and air temperatures rise. Early summer (June) often brings 14–20 °C (57–68 °F), while the warmest period in July and August commonly sees 18–24 °C (64–75 °F) in open water, with shallow bays occasionally reaching slightly higher values. In autumn (September–October) temperatures fall back toward roughly 8–14 °C (46–57 °F) as cooling progresses. In winter the surface normally approaches 0 °C (32 °F) and the lake frequently freezes; beneath the ice the water will be near 4 °C (39 °F), the temperature of maximum density.
Swimming in Lake Stirniai is generally permitted and is a common recreational activity in the warmer months, principally because it is public freshwater and accessible from shoreline spots. The most comfortable and safest bathing tends to occur when surface temperatures exceed about 18 °C (64 °F), typically in midsummer. Winter swimming is hazardous for most people due to ice and near-freezing water and should be attempted only by experienced cold-water swimmers with appropriate safety measures. As with any natural waterbody, swimmers should heed local advisories about water quality, currents, and informal lifeguard presence before entering.
