*** 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
The Markermeer, a large lake in the Netherlands, is closely associated with the city of Hoorn. As a body of water used for various recreational activities, including swimming, the water temperature in the Markermeer can fluctuate throughout the year. In the summer months, the lake’s surface temperature may rise to a comfortable 20-22°C (68-72°F), making it suitable for swimming. However, during the winter, the water temperature drops significantly, typically below 10°C (50°F), which is too cold for safe swimming without specialized equipment like wetsuits.
While swimming in the Markermeer is possible during the warmer months, it's important to note that the lake’s water quality and temperature may vary depending on local conditions such as rainfall and the presence of currents. There are specific swimming areas designated along the lake's shore in Hoorn where water quality is regularly monitored for safety. For those who want to swim outside of these areas, it is always advisable to check water conditions beforehand to ensure a safe and pleasant experience.
