When to go
Ustica is most reliable from May through October, with July and September the strongest overall choices.
Best overall window
Regular transport and full visitor services, long usable days, warming or warm water, and the strongest balance of sea access and crowds. July and September are the locally highlighted sweet spots.
Outside that window
May and October need weather flexibility, August needs advance booking, and November through April is not the default water-sport season.
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.
