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 water temperature of Ammersee varies throughout the year, reaching its warmest in July and August, where it can climb up to 22°C to 24°C. These comfortable water temperatures make it a perfect location for swimming, as well as for other water-based activities like sailing, kayaking, and stand-up paddleboarding. In the summer, the lake becomes a lively spot for locals and tourists alike, who flock to its beaches for a swim or a relaxing day by the water.
Swimming in Ammersee is allowed in designated bathing areas, particularly in towns like Herrsching, where the water quality is regularly monitored. The lake’s clear, fresh water is generally safe for swimming, and the shallow shorelines make it an ideal place for families with children to enjoy the water. However, visitors are advised to be cautious when swimming in the deeper parts of the lake, as there are areas with strong currents. The lake’s average depth of around 8 meters and maximum depth of 81 meters means there are some deeper zones where the temperature may drop, especially in the cooler months. In spring and autumn, the temperature of the water can fall to around 10°C to 14°C, making swimming less comfortable.
