*** 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
Plungė and its district are dotted with small lakes and slow rivers whose surface temperatures follow Lithuania’s temperate seasonal cycle. In spring (April–May) water in lakes and backwaters commonly ranges from about 4–10 °C (39–50 °F) as ice melts and waters warm slowly. In midsummer (June–August) popular swimming spots typically reach 18–24 °C (64–75 °F), with shallow, sheltered bays occasionally climbing to 25–26 °C (77–79 °F). Early autumn (September–October) sees cooling to roughly 10–18 °C (50–64 °F), while winter conditions usually drop waters to around 0–4 °C (32–39 °F) and many lakes freeze over for months.
Swimming in Plungė’s lakes and accessible river sections is commonly practiced during the ice-free season because temperatures are comfortable in summer and there are municipal bathing spots and informal beaches. Local authorities monitor popular sites for water quality and post advisories when cyanobacteria blooms, pollution, or safety concerns arise, so some places may be temporarily unsuitable. Rivers tend to be colder and may have currents or limited access, making them less used for casual swimming. As always, swimmers should follow signage, avoid ice, and be mindful of variable conditions.
