Log your sessions; that is how Windulu gets to know you.
The advice is a tool. You remain responsible for your own safety.
Julianadorp aan Zee lies at the top of North Holland, with wide beach accesses and plenty of room. There are waves in west to northwest, and it stays calmer than the spots further south.
The open water at Julianadorp faces WNW (290°). The safest wind directions to get on the water here are north, southwest, west and northwest (onshore or cross-onshore). With the wind from the northeast and south, it runs cross to cross-offshore: doable, but mind your position and don't go alone. With the wind from the east and southeast, it blows offshore and is dangerous: you'll be pushed off the beach onto open water (no-go).
