Log your sessions; that is how Windulu gets to know you.
The advice is a tool. You remain responsible for your own safety.
Katwijk is a compact spot on the coast of a genuine fishing village. The beach is narrower here than at the neighbours, but the local crew is active and the spot is a quarter of an hour from Leiden. In a good south-westerly there is fine wave riding on offer.
The open water at Katwijk faces NW (305°). The safest wind directions to get on the water here are north, west and northwest (onshore or cross-onshore). With the wind from the northeast, east, south and southwest, it runs cross to cross-offshore: doable, but mind your position and don't go alone. With the wind from the southeast, it blows offshore and is dangerous: you'll be pushed off the beach onto open water (no-go).
