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 Lammasjärvi, located in North Ostrobothnia near the town of Kuhmo, is a large and scenic freshwater lake known for its clean, slightly dark-colored water typical of northern Finland’s forest lakes. It is part of the Oulujoki river basin and has several islands and bays that influence local water temperatures. After the ice melts in May, the surface temperature of Lammasjärvi is around 4–7 °C (39–45 °F). During early summer, it rises to 13–16 °C (55–61 °F), and in July, the warmest month, the water usually reaches 17–20 °C (63–68 °F). In shallow areas close to the shore, the temperature can briefly rise to 21–22 °C (70–72 °F). By late September, the lake cools below 10 °C (50 °F), and it generally freezes again in November.
Swimming in Lake Lammasjärvi is allowed and popular among both locals and visitors during the summer. The water quality is good and suitable for bathing, with small public beaches and piers providing access for swimming. Although the lake’s water remains cool even at midsummer, it offers a refreshing and clean experience, especially on calm, sunny days.
