*** 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
Delft, a historic city located on the Schie River in the Netherlands, has a mild climate with water temperatures in the Schie River that vary throughout the year. In the colder months (from November to March), the water temperature typically drops to around 4-6°C (39-43°F), which makes swimming unsafe due to the cold conditions. During the summer months, the temperature of the river rises to between 16°C and 22°C (61-72°F), making it more favorable for swimming. However, there are no widespread designated swimming areas in the Schie River, and local swimming is generally done in controlled spots or designated lakes in the city.
In addition to water temperature, it’s important to consider water quality and safety regulations when swimming in the Schie River. Local authorities may issue swimming bans or warnings if the water quality is not ideal, especially after heavy rainfall or during certain seasons when pollution levels may rise. Public beaches and recreational swimming areas nearby, such as the Delftse Hout, provide more regulated environments for those seeking to swim in the city.
