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
Kalli Lake (Kalli järv) is a small Estonian waterbody whose surface temperatures follow the typical seasonal pattern of northern temperate lakes. In spring, as ice melts, surface water commonly ranges from about 1–10 °C (34–50 °F). Summer brings the warmest conditions, often between 16–24 °C (61–75 °F) for accessible swimming spots, with shallower bays warming fastest. In autumn temperatures fall back to roughly 4–12 °C (39–54 °F) as the lake cools and mixing increases. During winter the lake usually freezes; water beneath the ice is close to 0–1 °C (32–34 °F) and surface conditions are not suitable for ordinary swimming.
Swimming in Kalli Lake is generally possible and common in summer months when temperatures are comfortable, but it is subject to local conditions and rules. Public access and traditional bathing areas typically make swimming allowed, yet occasional restrictions can apply for reasons such as private shoreline ownership, water-quality advisories (for example algal blooms), or safety concerns like lack of lifeguards and sudden depth changes. Visitors should check local signage and recent water-quality information before entering, and be mindful that outside the warm season cold water presents hypothermia risks even in short exposures.
