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 Gouwe is a river in the western Netherlands, flowing through the province of South Holland. It connects various waterways, including the Old and New Gouwe, and plays an essential role in the regional water management system. The water temperature in the Gouwe varies seasonally, with summer temperatures generally ranging from 15°C to 20°C (59°F to 68°F). During the colder months, water temperatures can drop to around 4°C to 6°C (39°F to 43°F), making it uncomfortable and unsafe for swimming.
While the Gouwe is a picturesque river, swimming is not commonly recommended due to water quality concerns. The river passes through both urban and agricultural areas, which can affect the water's cleanliness. Additionally, there are sections with strong currents, particularly near locks and bridges, where swimming can be dangerous. For those seeking safe swimming opportunities, it’s better to visit designated areas like lakes or specific swimming zones that are monitored for water quality and safety.
