*** 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 Danube River, Europe's second-longest river, stretches across ten countries and has a variety of water temperatures depending on the region and time of year. In the warmer months, particularly from late spring to early autumn, water temperatures in the Danube can range from 18°C to 25°C (64°F to 77°F). In some areas, such as those around the city of Vienna or Budapest, temperatures can be ideal for swimming, with calm and warm water making it a popular choice for both locals and tourists. However, in the colder months, temperatures can drop significantly, especially in the upper sections of the river, where it can approach 4°C to 6°C (39°F to 43°F), making swimming less feasible due to the cold and fast-flowing waters.
Swimmers should always take caution when swimming in the Danube, as the current can be quite strong, particularly in certain sections. The river’s flow speed varies, but it can exceed 6 km/h (3.7 mph) in some areas, which can pose a challenge to swimmers. Moreover, water quality can fluctuate depending on the location and time of year, with the river sometimes experiencing higher pollution levels due to industrial runoff or agricultural practices. It’s essential to swim in designated areas, often near beaches or resorts, where the water is checked regularly for safety.
