Water Temperature: Daily Trends, Historical Records, and Forecast
❌ 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
Holbæk (Danish: Holbæk) in Region Zealand sits by fjord and inland water bodies that behave much like small lakes in terms of temperature. Seasonal surface temperatures in these waters typically range from about 0–4 °C (32–39 °F) in the depths of winter, through roughly 4–12 °C (39–54 °F) in spring, to commonly 18–22 °C (64–72 °F) in summer; during warm summers surface readings can briefly reach around 24 °C (75 °F). In autumn temperatures fall back toward 10–16 °C (50–61 °F) as cooling begins. Local variation depends on wind, depth and freshwater inflow, so individual spots can be a few degrees warmer or cooler than these averages.
Swimming in the Holbæk area is generally allowed and popular at designated bathing sites and beaches during the warmer months because public access is provided and authorities monitor water quality. Bathing water quality is checked regularly, but swimming may be discouraged or temporarily closed if algal blooms, pollution or high bacterial counts occur after heavy rain. Cold-water swimming is also practiced year-round by some residents, but it requires experience and caution because low temperatures increase risk of cold shock. As always, swimmers should observe local signage and guidance before entering the water.
