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 Altmühl is a river in southern Germany, flowing through the Bavarian region and ultimately joining the Danube. Known for its calm waters and scenic landscapes, the Altmühl is a popular destination for outdoor activities, including swimming, kayaking, and hiking along its banks. Water temperatures in the Altmühl vary depending on the season, but generally, the river is cool to moderately warm, with temperatures ranging between 5°C (41°F) in early spring and 20°C (68°F) in summer. The warmest months, from June to August, provide the most comfortable conditions for swimming, making it an ideal location for those looking to cool off during the summer heat.
During the summer months, particularly in July and August, the Altmühl reaches optimal swimming temperatures between 18°C and 22°C (64°F to 72°F). These temperatures are considered perfect for a refreshing swim, especially in calm sections of the river where the current is gentle. The Altmühl's shallow sections with slower-moving waters also make it safer for swimmers of all skill levels. However, in certain areas, such as near weirs or after rainfall, stronger currents can occur, so it's essential to remain cautious and aware of the river's conditions before entering.
