Climate Papua New Guinea
Papua New Guinea lies in the tropical climate because of its proximity to the equator. Due to its different topography with mountain regions up to 4500 meters altitude, the climate is very different regionally. At the coasts there is a quite hot and always humid tropical climate. The average maximum values usually vary between 28 and 32 degrees. From December to April the humidity is very high. In the highlands, the annual temperature fluctuations are also low, but the temperatures are lower overall than in the coastal regions. Above an altitude of about 1500 metres, the climate is temperate. At altitudes above 2000 metres frost is possible at night. In general, a distinction can be made between a drier and a wetter season. From December to April the humid northwest monsoon provides large amounts of precipitation. Tropical cyclones can also occur. Between May and November the somewhat less humid southeast trade wind blows. From June to September it rains much less frequently and in smaller quantities, especially in the south. The annual precipitation varies very strongly with the location and the altitude. They lie between 1100 and 6000 mm per year. Snow also falls at the highest altitudes.
For a trip to Papua New Guinea we recommend the drier months June to September. Then also the temperatures are not quite as high as in the summer months.
