Each night counts under the direction of its strongest hour of wind. Wind and gusts are modelled for the area (ERA5, about 28 km across), not measured in the bay. “1–2” means fewer than 3 boats.

Nearby anchorages

AIS shows only boats that carry it and that a receiver hears, so no boats on AIS never means an anchorage is empty or unsuitable. Boats that live here (at their own berth or mooring, or a week or more in one place) are left out, and boats in marinas and at piers are counted apart from the anchorage's nights. Not for navigation.
