Overview of Nusa Penida's Climate
Nusa Penida experiences a tropical climate with two distinct seasons: the dry season and the wet season. These seasonal changes affect not only the weather above water but also the diving conditions and marine life activity below the surface.
Diving Conditions by Season

Tips for Diving in Different Seasons
1. Dry Season:
