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
In Groningen, a city in the north of the Netherlands, water temperatures in rivers like the Westerhaven or the Van Starkenborgh Canal generally remain cooler throughout much of the year. The water temperatures can reach around 15–20°C (59–68°F) in the summer months, making swimming in these areas pleasant during warmer weather, but still quite cool compared to southern regions. In winter, the temperature drops significantly, and the rivers can get very cold, usually hovering around 3-5°C (37–41°F), making it unsuitable for swimming.
In general, swimming is permitted in some areas of Groningen, especially around designated swimming locations or recreational lakes such as Paterswoldsemeer and Hoornsemeer, which are more popular for leisure activities. However, the rivers like the Westerhaven and Van Starkenborgh Canal may not be the most ideal for swimming due to the stronger currents and water quality concerns, so it's better to check local regulations or find a designated swimming spot during the summer months. Always be aware of water quality advisories, as the water may sometimes be considered unfit for swimming.
