Checking the wind…
North Holland
Too little wind to ride.
No day with a go window this week.
Cross-offshore wind. Only with rescue or experience.
The current pulls you offshore, watch your position.

Log your sessions; that is how Windulu gets to know you.
The advice is a tool. You remain responsible for your own safety.
Kitesurfing not allowed (city water). A windsurf and wing spot; small and shallow, so foiling is limited.
The open water at Nieuwe Meer (Amsterdam) faces NE (45°). The safest wind directions to wing foil here are north, northeast and east (onshore or cross-onshore). With the wind from the southeast, south, southwest, west and northwest, it runs cross to cross-offshore: doable, but mind your position and don't go alone.
