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
Mummelsee, located in the Black Forest region of Baden-Württemberg, Germany, is a popular lake known for its picturesque surroundings and cold, mountain-fed waters. The lake is situated at an altitude of about 1,036 meters above sea level, which means that its water temperature remains relatively cool throughout the year. During the summer months, the water temperature typically ranges from 18°C to 22°C, which is refreshing but can be a bit chilly for those who prefer warmer swimming conditions. Despite this, many visitors enjoy swimming in Mummelsee, especially on hot days when the cool water provides a pleasant escape from the heat.
Although Mummelsee is a popular spot for recreational activities such as boating and hiking, swimming is allowed in certain areas around the lake. The water is usually clear and clean, but the lake’s colder temperatures mean that swimming is more common during the late spring and early autumn months, when the water is at its warmest. In winter, the lake often freezes over due to its altitude, making swimming impossible. Nonetheless, Mummelsee remains a highly regarded location for nature lovers, offering scenic views, walking trails, and the chance to cool off in the refreshing water during the summer.
