Papua New Guinea is a land of extraordinary cultural diversity and pristine natural beauty in the Pacific. From the vibrant traditions of over 800 indigenous cultures to world-class diving sites and the legendary Kokoda Track, PNG offers adventurers an unparalleled experience in one of the world's last frontiers.
Papua New Guinea has a tropical climate with temperatures consistently warm year-round, typically 25-33°C in coastal areas and cooler (15-25°C) in the Highlands above 1500m. The country experiences two distinct seasons: a dry season from approximately May to October and a wet season from November to April. Humidity is high throughout the year, often 75-90%, making the dry season significantly more comfortable for outdoor activities and trekking. The extreme rainfall (Kokoda corridor receives up to 4,500mm annually) means wet season travel on trails and to remote areas is substantially more challenging.

The seasons
What to expect in each part of the year.
Dry_season
Months: May-October
PNG's prime travel season with lower humidity, less rain, and more reliable weather for Kokoda trekking, diving, and outdoor activities. The Goroka Show (September) and Mt Hagen Show (August) both fall in this period.
Wet_season
Months: November-April
Heavy rainfall, high humidity, and regular tropical storms make outdoor activities challenging. Kokoda Track becomes dangerously slippery and river crossings hazardous. Diving visibility can be reduced though some marine species are more active.
Shoulder_early
Months: April
Transitional month with decreasing rainfall and improving conditions. Reasonable time to visit with lower crowds than peak season.
Shoulder_late
Months: November
Transitional month with increasing rainfall. The Alotau Canoe and Kundu Festival takes place in November and is worth planning around despite higher rainfall.
Crowds & peak times
When to expect tourists and when to avoid them.
- High Season

- Shoulder Season
- May and October offer good weather with lower tourist numbers and more available accommodation.
- Low Season
