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
Lake Konnivesi is a large and deep lake situated in the Päijät-Häme region of Southern Finland, forming part of a significant waterway network. Swimming is freely accessible along its shores, including established public beaches, a right protected by Finland's Everyman’s Rights. This legal principle ensures the public can use natural waters for recreation. Konnivesi’s water quality is generally good, supporting safe seasonal swimming, with the presence of deep areas influencing the overall temperature regime.
The lake’s water temperature is strongly seasonal. During the cold winter, from approximately December to April, the lake is typically ice-covered, with the water below the surface consistently maintaining a very cold temperature, ranging from 0∘C to 4∘C. The most pleasant period for surface swimming is concentrated in July and early August. During this peak summer time, surface temperatures in shallower, sheltered areas can typically reach an approximate range of 19∘C to 22∘C. Outside of the brief summer warm spell, the water remains too cool for casual bathing, though it is utilized by dedicated cold-water swimmers who continue the practice throughout the colder months.
