*** 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
Prienai (in Lithuanian - Prienai) lies along the Nemunas River and near several small lakes and reservoirs. Water temperatures in these inland waters vary by season: in winter surface temperatures typically fall to around 0–4 °C (32–39 °F) and often the lakes are ice-covered; in spring they rise from roughly 4–12 °C (39–54 °F) as ice melts and the water stratifies; in summer average surface temperatures are commonly between 18–24 °C (64–75 °F), with short spells reaching 25–26 °C (77–79 °F) during heat waves; in autumn the surface cools to roughly 10–16 °C (50–61 °F) as the weather turns cooler. Deeper water remains colder and changes more slowly than the surface.
Swimming in Prienai’s lakes and river sections is generally permitted and popular in the warmer months when surface temperatures are comfortable. Local beaches and designated bathing areas are used because they offer safer access, shallower water that warms up faster, and sometimes lifeguard supervision. Outside summer, swimming is discouraged due to cold water, hypothermia risk and, in winter, ice hazards. Additionally, water quality and safety are monitored periodically, so swimming may be limited at specific sites for health or safety reasons.
