❌ As of today, the minimum water temperature ranges less than 41°F (5°C). Such water is extremely cold and not recommended for swimming without proper preparation. In these conditions, the risk of hypothermia is very high, and prolonged exposure to the water can be hazardous to your health. If you decide to swim, it is important to have the appropriate gear, such as a wetsuit. Typically, only experienced swimmers or those who practice winter swimming venture into such waters. It is important to note that these swimming tips and recommendations apply only in good weather.

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
Lokka Reservoir, known in Finnish as Lokan tekojärvi, is an artificial lake in central Lapland, located mainly within the Sodankylä municipality. It is one of Finland’s largest reservoirs, created to regulate the flow of the River Kemijoki. Due to its northern latitude and broad surface area, the water temperature in Lokka Reservoir remains cool even in summer. In spring, after the ice melts in late May or early June, the surface water temperature is around 3–6 °C (37–43 °F). During midsummer, it rises gradually to 12–16 °C (54–61 °F), and in July, during the warmest period, the water typically reaches 17–19 °C (63–66 °F). Shallow areas may briefly warm to about 20 °C (68 °F). In autumn, the temperature drops quickly below 10 °C (50 °F), and the lake usually freezes again by late October.
Swimming in Lokka Reservoir is allowed, but it is not very common because of the low water temperature and variable water levels. However, on calm summer days, locals and visitors sometimes take short swims near sandy shores or piers, enjoying the clear air and quiet landscape. The water is clean and pure, making it suitable for brief, refreshing dips that capture the wild essence of Lapland’s northern nature.
