❌ As of today, the minimum water temperature ranges from 41°F (5°C) to 47°F (8°C). This water temperature is still quite low, and swimming in such conditions may only be comfortable for hardened individuals. It is recommended to limit the time spent in the water to avoid hypothermia. For those not accustomed to cold water, it is better to refrain from swimming. However, if you decide to enter the water, it is advisable to wear a warm wetsuit for protection against the cold. It is important to note that these swimming tips and recommendations apply only in good weather.

*** 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
Valkjärvi, located in the Uusimaa region near Lohja, is a relatively large lake popular for recreation and features established swimming opportunities. Swimming is freely allowed along the lake’s accessible shoreline and at designated public beaches, a fundamental right enshrined in Finland's Everyman’s Rights. Due to its status as a local water source and recreational spot, the water quality is monitored by local authorities, with recent reports generally indicating clear water and low levels of algae, which helps ensure hygienic and safe conditions for public bathing during the season.
The lake experiences the characteristic seasonal temperature range of Southern Finnish lakes, with a prolonged period of ice cover. During the winter, typically spanning from December to April, the lake freezes over, and water temperatures beneath the ice remain near the maximum density point, generally ranging from 1∘C to 4∘C. In the peak summer month of July, the surface water warms considerably, with nearshore temperatures commonly ranging from 19∘C to 22∘C. As a deeper lake in some parts, a thermal layer may exist, meaning that temperatures drop rapidly below the surface layer. Casual swimming is predominantly enjoyed during the warm summer window.
