Water Temperature in Katwijk aan Zee: General Trends and Swimming Opportunities
Katwijk aan Zee is a coastal town in the Netherlands, located on the Oude Rijn River, which flows into the North Sea.

In the winter, the water temperature drops significantly, often to around 4°C to 6°C (39°F to 43°F), making swimming very uncomfortable and potentially dangerous.
While Katwijk aan Zee is better known for its beautiful beaches along the North Sea, the Oude Rijn itself also offers areas where people may swim, especially in the warmer months. However, the river can be busy with boat traffic, and its waters can be affected by tides, so caution is needed.
