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.

The Lek is a major river in the Netherlands, flowing through the provinces of Utrecht and South Holland. It is part of the Rhine River system and serves as an important waterway for shipping and transportation. The water temperature in the Lek varies seasonally. In the summer months, the temperature can range from 16°C to 22°C (61°F to 72°F), making it more comfortable for outdoor activities, including swimming. However, the temperature can drop to around 5°C to 8°C (41°F to 46°F) in the winter, making it too cold for safe swimming.
Swimming in the Lek is generally not recommended due to the river's strong currents and fluctuating water levels, especially in areas near locks, dams, or bridges. The water quality is also a concern in certain parts, as it passes through urban and industrial regions. While the river offers beautiful views and opportunities for boating, it is better to swim in designated swimming areas or lakes, where water quality is monitored for safety.
