Best Time to Visit Papua New Guinea
Typically tropical, Papua New Guinea’s climate is hot, humid and punctuated by heavy rains during the wet season, November-April. The dry season months, May-October, are generally the most pleasant, and also coincide with many of PNG’s festivals. Hiking and wildlife watching are also more comfortable during the dry season, diving is good year round, while surfing on the north coast is best in the wet season.

Along the coast and lowlands of Papua New Guinea, the temperature averages around 28°C year round. It’s generally cooler during the May-October dry season, with minimums of 23-24°C. Venture into the Highlands and the temperature drops significantly – you can expect night frosts above 2,100m. The relative humidity in PNG is high – ranging from 70-90%, but both heat and humidity are tempered by southeasterly trade winds that blow during the dry season.
