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.

The Nemunėlis in Lithuania typically shows a clear seasonal pattern in water temperature. In winter the river often approaches freezing, with surface temperatures around 0–2 °C (32–36 °F) and frequent ice cover during cold spells. Spring brings a steady rise as meltwater and warming air push temperatures into roughly 2–12 °C (36–54 °F). In summer the warmest stretches commonly range from about 14–22 °C (57–72 °F), though shallow, slow-flowing pools can be a few degrees warmer on hot days. Autumn sees a decline back toward 6–14 °C (43–57 °F) as air temperatures drop and flow increases.
Swimming in the Nemunėlis is generally possible and is practiced locally in the warmer months, but whether it is advisable depends on place and conditions. Calmer, shallower sections with summer temperatures above roughly 16–18 °C (61–64 °F) are comfortable for short swims, while colder water presents risks of cold shock and reduced endurance. Strong currents, submerged obstacles, variable water quality and occasional local restrictions mean swimmers should pick well-known, supervised spots when available, check recent local guidance or signage, and avoid entering the river alone or after heavy rains.
