Climate Overview
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.
