Water Temperature: Daily Trends, Historical Records, and Forecast
❌ As of today, the minimum water temperature ranges from 47°F (8°C) to 50°F (10°C). This is still cool water, suitable only for experienced swimmers or those accustomed to cold water. Swimming in such conditions is possible, but not recommended for prolonged periods. Extra caution should be taken during extended exposure, as the cold water can cause heat loss and lead to hypothermia. For added comfort, special clothing can be used. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

*** 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 Iller River is a significant tributary of the Danube, flowing through the Bavarian region of Germany. Originating in the Allgäu Alps near Oberstdorf, it runs through picturesque landscapes and is known for its strong current and clear waters. The river's water temperature varies depending on the season, ranging from 2-5°C (35-41°F) in winter to around 15-20°C (59-68°F) in summer, making it more inviting for recreational activities during warmer months.
While swimming in the Iller is possible, it requires caution due to the strong currents and uneven depths in some areas. Designated swimming spots or calm sections near towns like Kempten or Illerbeuren are more suitable for water activities. Besides swimming, the river is popular for kayaking, rafting, and hiking along its scenic banks. For those looking for a refreshing experience, the Iller provides a natural setting to enjoy the water during summer, but it's always advisable to check local conditions and follow safety guidelines.
