The waves can get very big. The waves start at 5 Bft. West wind makes clean waves, Northwest destroys the waves a bit, but they get even bigger. The waves can get up to 2.5m. The waves break close to the beach. There are some stones in the water, but they do not really mater.
The water temperature in comparison to other Baltic Sea spots is always colder. I would always use my thicker wetsuit. A wetsuit is necessary nearly all over the year. The water is between 5-20°C (spring to summer), air temperature is in the average 18°C (in summer) and can go up to 30°C. If you have the adequate wetsuit you can surf from April to November. Off-season is possible but very cold.
There are lots of kitesurfers, windsurfers and surfers. Kitesurfers and windsurfers should stay in one zone. Surfers normally are further west, which has a big parking lot next to it.
