❌ 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
The Porvoonjoki River, or Borgå å, flows through the municipality of Orimattila in Päijät-Häme, offering localized swimming opportunities. Swimming is permitted along the river's accessible banks and at designated public spots, a right secured by Finland's Everyman’s Rights. However, rivers require greater caution due to currents, and water quality can be variable, particularly after heavy rains, making supervised beaches in nearby lakes often a safer alternative. The municipality’s public health authority monitors water quality at official spots during the summer season.
The water temperature in the Porvoonjoki is typical for a Southern Finnish river, experiencing sharp seasonal changes. During the winter months, from approximately November to April, the river is often ice-covered, with the water temperature near freezing, typically between 0∘C and 4∘C. The season for comfortable swimming is short, peaking in July. During this time, the surface temperature can rise significantly, reaching an approximate range of 19∘C to 23∘C. Outside of this mid-summer peak, the water quickly becomes too cold for casual recreation, mainly attracting the dedicated community of cold-water bathers.
