December in Koror: expect compromises
Days in December average 28°C (82°F) and humidity near 81% — front-load outdoor plans before the heat builds and treat the middle of the day as indoor time.
This is the year's wettest stretch at 496 mm, but with about 24 days with 6+ hours of sunshine it is not a total loss; an indoor fallback covers the risk.
