❌ 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. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

*** 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
Borrevannet in Vestfold County, Norway, is a small inland freshwater lake that experiences marked seasonal variations in surface temperature. In winter the water commonly approaches freezing, around 0 to 2 °C (32 to 36 °F). During spring temperatures typically rise to roughly 3 to 10 °C (37 to 50 °F) as the ice melts and the sun warms shallow layers. In summer the surface can reach comfortable bathing values on warm days, often ranging from about 15 to 22 °C (59 to 72 °F), though cooler conditions are possible early and late in the season. In autumn a cooling trend brings temperatures back down to roughly 8 to 15 °C (46 to 59 °F) as air temperatures drop and mixing increases.
Swimming in Borrevannet is generally possible and commonly practised when summer temperatures are highest, because it is accessible freshwater with shoreline entry points. There are no inherent physical reasons why bathing would be banned, but local rules, private land ownership along parts of the shore, water quality test results and occasional surface vegetation or algal developments can influence safety and comfort. Visitors should check current municipal or local advisories, avoid swimming after heavy rainfall if runoff is an issue, and be mindful that lifeguards are usually not present at smaller lakes.
