*** 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
Vienna, the capital city of Austria, is situated along the Danube River, which flows through the city and offers both locals and tourists the opportunity to enjoy its waters. The Danube in Vienna, particularly during the summer months, becomes a popular destination for various water activities, including swimming. The water temperature in the Danube River varies depending on the season. In the colder months, particularly from late fall to early spring, the water temperature can drop to as low as 6°C (43°F), making swimming less appealing. However, during the summer, the water warms up to a much more comfortable temperature, typically ranging from 18°C (64°F) to 22°C (72°F), depending on the heatwave and weather conditions.
Swimming in the Danube is a popular activity in Vienna during the summer, with many designated swimming areas and beach-like spots such as the Donauinsel (Danube Island) offering a safe and enjoyable experience. The Danube's water is generally clean, though it is important to note that river conditions can fluctuate, so it is recommended to swim only in designated areas where the water quality is monitored. The numerous recreational spots along the river offer not only swimming but also opportunities for boating, cycling, and picnicking, making the Danube a key feature of Vienna's outdoor lifestyle.
