Narrow beach with sand and lots of pebbles and bigger stones. Further north no beakers. Grassy dam to rig. Further north the beach will be more packed during warm summer days.
Summer is nice and warm. High season a shorty is ok, a few weeks with just shorts is possible. Usually a wetsuit is always needed. Water max 22°C in summer, normally around 15°C. Winter gets cold, but a thick wetsuit, gloves, mask and shoes make kiting almost year-round possible. Air: summer between 20-30°C, spring and fall around 15°C.
Get to Fehmarn and take the first exit after the bridge and follow signs to Landkirchen, then to Petersdorf and Bojendorf. In Bojendorf follow signs to Wallnau and drive for 1km. Drive to the dam where the streets makes a left curve, follow it for about 200m and park in the parking lot to the left (parking fees during season). Walk onto the dam for about 100m.
