The climate in Papua New Guinea is tropical.
Lowland and coastal areas are generally hot and humid, while the Highlands are less humid and cooler, ranging from 12-28˚C. In both areas the days are generally fine, but often there are clouds in the afternoon resulting in rain late afternoon and evening.
There are different wet seasons in the various regions, most notably in the Sepik region between November and March. It can be difficult to distinguish between seasons elsewhere as weather is generally very localised.
