flatflatThe Aartalsee spot offers a flat water surface ideal for freestyle and wakestyle. Launching is done directly from the club's grassy beach, with a wide and clear take-off area on the banks.
The dominant side-shore winds come from the NW or W, blowing across the lake for consistent power without risking offshore that could pull the kite away. The navigation area extends along the entire length of the lake, about 2 km, with enough space for jibes and tricks without hassle.
No tide since it is a freshwater lake, so conditions remain constant. However, be cautious of shallow areas near the shores where you need to navigate carefully during low wind sessions.
Ideal conditions are a side-shore NW or W wind between 12-20 knots, for a flat water surface and consistent power. Avoid pure onshore E which may make the spot turbulent.
The water state is generally flat to light chop, perfect for beginners and intermediates seeking stability. In strong wind, a small chop forms but remains manageable.
No waves, thanks to the shelter of the surrounding hills that protect the lake from violent storms.
As a freshwater lake, there is no significant current at the Aartalsee. The water remains calm without the influence of tides or powerful rivers.
Only strong winds can create a slight directional chop, but nothing dangerous for riders.
