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
The Ill River flows through the Vorarlberg region of Austria, winding its way through the town of Feldkirch before joining the Rhine River. This river is fed by mountain runoff and is known for its cool, clear waters. During the summer months, the water temperature of the Ill typically ranges from 8°C to 15°C (46°F to 59°F), which can be refreshing but may be too cold for extended swimming sessions. The river’s temperature remains relatively cool throughout the year due to its alpine source, although the water may warm slightly in the lower reaches as it moves through less mountainous terrain.
Swimming in the Ill River is possible in certain sections, especially where the water flow is slower and the river becomes calmer, such as near Feldkirch. However, due to the river's fast currents and cold temperatures, swimming can be challenging, particularly in the upper reaches. It is advisable to be cautious of the river’s strong flow, which can increase significantly after heavy rain, making it more dangerous for swimming. For those seeking a more comfortable and safer swimming experience, nearby lakes or public swimming pools offer a warmer and more controlled environment.
