When to go
The European Netherlands is not a singleseason dive destination.
Best overall window
European coast warmest water 16°C to 20°C, longer days, and the best odds of workable shore and charter windows
Outside that window
Coldwater season 4°C to 8°C, short daylight, and rougher North Sea conditions
Start with the overall answer, then switch only when scuba, freedive, snorkel, or topside timing changes the trip in a meaningful way.
The overall row stays visible so you can compare it against the currently selected scope.

These do not replace the overall planner. Use them only if a specific animal or event is driving your trip dates.
