*** 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
Šiauliai sits near several lakes, the largest being Lake Rėkyva and the popular Talkša in the city center, where water temperatures follow a clear seasonal pattern. In spring (April–May) surface temperatures typically rise from about 4–12 °C (39–54 °F) as ice melts and the water warms. Summer (June–August) is when lakes are at their warmest, commonly ranging between 17–24 °C (63–75 °F) and occasionally reaching the mid-20s °C (mid-70s °F) during heat waves. In autumn (September–October) temperatures fall to roughly 8–15 °C (46–59 °F). In winter the lakes are near freezing, usually around 0–4 °C (32–39 °F) at the surface under ice, making open-water swimming impractical and unsafe without special preparations.
Swimming in Šiauliai’s lakes is generally allowed, especially at designated bathing beaches such as those on Rėkyva and Talkša, where summer recreation is common and some sites are monitored for water quality. Local authorities may post advisories or close beaches if bacterial counts are high or during unsafe weather. Lifeguards are not always present, so swimmers should heed signs, be aware of temperature-related risks like cold shock outside the warm months, and avoid swimming when ice is present. Public access and recreational use are the main reasons swimming is permitted, subject to seasonal safety and environmental checks.
