Additional Information
- The climate is closely linked to agriculture (taro cultivation and copra production) and fishing.
- Many Christian events have developed outdoor worship and festivals tailored to the rainy and dry season climates.
- The state anniversaries aim to preserve and pass on regional culture, with the seasonal climate conditions influencing the organization of events.
