Untersee is a large freshwater lake on the Switzerland-Germany border in the Alpine region. The western shoreline faces west toward the water, with extensive agricultural land and greenhouses visible inland. This is a sheltered lake environment with limited wind exposure due to surrounding terrain and relatively calm conditions typical of inland Alpine lakes.
The spot's defining characteristic is its extremely low wind reliability at 1.6%, making consistent kitesurfing sessions rare. Average wind speeds of 4.0 knots fall well below the 10-12 knot minimum required for most kitesurfing. The shallow nearshore waters and agricultural development suggest weak thermal winds typical of protected lake settings.
Best conditions occur with northerly winds (side-shore), though occurrence is infrequent. This location suits only advanced riders capable of light-wind techniques or those using large kites. The cold water temperature requires appropriate thermal protection. Primary considerations include the unpredictable wind pattern, shallow areas requiring careful water entry/exit, and the lake's recreational boat traffic. Alternative spots on larger, more exposed water bodies would offer more consistent conditions.
