*** 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.

Location & Local Information
Passau is a beautiful city in Bavaria, Germany, known as the City of Three Rivers because the Danube, Inn, and Ilz rivers merge here. The city's unique location has a significant influence on the water temperature of the Danube River. Water temperatures in great rivers like the Danube are heavily influenced by the weather conditions, with warmer temperatures in the summer months and lower temperatures in winter, but also by the river's depth, flow speed and its source. According to the survey studies, the river's temperature varies from approximately 4°C in the colder months to up to 22°C during a hot summer.
While this might make the idea of swimming in the Danube in Passau a tempting prospect, it is important to note some considerations. Despite the relatively warm summer temperatures, swimming in the Danube is generally not recommended. This is due to a combination of strong currents, sudden changes in depth, boat traffic, and water purity, all of which can pose a number of potential risks to swimmers. Moreover, there are also legal restrictions in place preventing swimming in certain areas of the Danube River. It is advised to always check for the permitted areas to swim for safety reasons and to comply with local laws and regulations. Public swimming pools or bathing lakes in or around Passau are therefore a better and safer alternative for swimming during warm weather.
