*** 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.

The Agger River flows through North Rhine-Westphalia, originating in the Bergisches Land and joining the Sieg River near Troisdorf. The water temperature in the Agger typically ranges from 5°C to 18°C (41°F to 64°F), depending on the season. During the warmer months, the river offers pleasant conditions for outdoor activities, although its cooler temperatures may limit prolonged swimming sessions.
Swimming in the Agger is generally not widespread due to its narrow size and variable currents. However, in calm and shallow stretches, locals occasionally enjoy wading or dipping. The river is more popular for activities such as kayaking, fishing, and hiking along its scenic banks. As with many natural rivers, it is essential to observe local guidelines and avoid areas with strong currents or restricted access.
