Castricum aan Zee Swimming Forecast
Strandslag 38 · Netherlands
Castricum aan Zee scores 77/100 for swimming today at its best ability level (expert). The beach faces NW. A dune-backed North Sea beach with a sandy break on shifting sandbars, rated for advanced riders; sideshore wind gives cleanest conditions, onshore wind brings larger, messier shorebreak. A submerged shipwreck lies in the north kite zone. Kitesurfing and windsurfing run year-round except in front of the pavilions. Blue Flag status. A volunteer brigade with a rescue boat and jetski covers May–mid-September; sandbars are shallower and choppier at low tide.
