*** 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 Keitele, one of the largest lakes in Central Finland, is renowned for its excellent water quality, which ranges from good to excellent, making it a highly desirable location for swimming. Swimming is generally permitted under Finland's Everyman’s Rights, allowing public access to its extensive shoreline for recreation. Several municipalities bordering the lake, such as Äänekoski and Viitasaari, maintain official beaches where visitors can swim safely, and the clean, clear water enhances the experience throughout the summer.
The seasonal water temperature in Keitele dictates the swimming opportunities. During the winter, the lake is frozen from December to April, with water temperatures near 0∘C to 4∘C. The main swimming season is mid-summer. In July and early August, the surface water typically warms to between 17∘C and 22∘C. Exceptionally warm summers can see surface temperatures temporarily exceed 25∘C, although the large size of Keitele can sometimes lead to localized upwelling of colder deep water.
