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
Deventer, a picturesque city in the Netherlands situated along the IJssel River, experiences moderate water temperatures throughout the year. In the winter months, the water temperature drops significantly, often ranging from 4-6°C (39-43°F), which makes swimming unsafe due to the cold conditions. However, during the summer, the water temperature in the IJssel River can rise to between 16°C and 22°C (61-72°F), which is more comfortable for recreational activities, including swimming. Despite the more favorable temperatures in the summer, there are no dedicated public swimming areas in the river itself. Residents and visitors often opt for designated swimming locations such as pools or lakes for a safer experience.
The water quality in the IJssel River also fluctuates, which is a consideration for swimming. After periods of heavy rain or during the warmer months when algae blooms are more common, local authorities may issue warnings or advisories, making it unsafe to swim. Swimming in the river is not generally encouraged due to fluctuating water quality, and it is important to check local updates for any restrictions. Fortunately, there are nearby recreational areas such as the IJsselstrand, where people can safely enjoy water activities under controlled conditions.
