*** 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
Lake Kemijärvi, a large reservoir in Finnish Lapland, is a central hub for summer recreation, offering excellent swimming opportunities, particularly near the town of Kemijärvi. Swimming is widely permitted at designated public beaches and along accessible shores, secured by Finland's Everyman’s Rights. This legal right allows public access to water bodies for recreational use, provided the environment and private areas are respected. Local beaches, like the one at Hietaniemi, often boast water quality rated as excellent, providing a safe and enjoyable environment for bathers during the brief Arctic summer.
The water temperature in Kemijärvi is governed by the northern climate, resulting in cold conditions for most of the year. The lake is frozen for a long period, typically from October to May, with the water under the ice remaining between a chilly 0∘C and 4∘C. The optimal period for comfortable swimming is short, primarily in July. During this peak, the surface temperature in the sheltered, shallow areas of the lake can warm up to a maximum range of 17∘C to 22∘C. Outside of this brief window, the water is cool, mainly suitable for a quick, invigorating dip or for the established Finnish tradition of cold-water swimming.
