*** 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 Mastis (Mastis) typically follows the seasonal temperature patterns of small Lithuanian lakes. In spring (April–May) surface waters commonly warm from about 4–12 °C (39–54 °F) as ice melts and air temperatures rise. Summer (June–August) brings the warmest conditions, with surface temperatures usually between 17–24 °C (63–75 °F), and occasionally reaching 25–27 °C (77–81 °F) during heat spells. In autumn (September–October) temperatures decline to roughly 8–15 °C (46–59 °F) as cooling begins. Winter sees surface water at or near freezing, often covered by ice, with liquid water beneath the ice around 0–2 °C (32–36 °F).
Swimming in Lake Mastis is generally possible in the warmer months where there is public access and no local prohibitions, because most Lithuanian lakes are open for recreational use. Suitability for bathing depends on water quality, safety conditions, and the presence of designated beaches or lifeguards; poor water quality, private shoreline, underwater hazards or official restrictions can make swimming inadvisable. Ice swimming is practiced by some people in winter, but it requires experience, safety measures and awareness of ice thickness and health risks. Always check local signage and current water-quality information before entering.
