Papua New Guinea Climate

By | August 6, 2021

Although Papua New Guinea is located directly on the equator, the climate is not tropical in the whole country, but varies greatly. Because Papua New Guinea also has mountains up to 4,500 m high. Therefore, the climate ranges from tropical to alpine.

The lowlands and the coastal zones have a tropical, always humid and hot climate. The temperatures hardly fluctuate with average values ​​of 26 to 30 ° C. It is warmest with peaks of 39 ° C in December / January, and the coldest with only 23 ° C in June / July. The water temperature is constantly between 26 and 29 ° C. The high humidity is also tropical, causing uncomfortable humidity in the coastal regions, especially from December to April.

In the highlands, too, the temperatures are very even; however, they decrease more and more with increasing altitude. At almost 2,000 m, an average of 16-17 ° C is still measured. In addition, the weather is increasingly changing from a moderate to an alpine climate. On some peaks in the Owen Stanley Mountains, permafrost and a permanently closed snow cover can be found.

There are two seasons in Papua New Guinea, a wetter and a drier one. From December to April, the northwest monsoon brings very humid air masses from the Pacific and is responsible for the high levels of precipitation that then fall. Typhoons threaten the country during this time of year.

Between May and November, the drier southeast trade wind dominates. From June to September in particular, it rains significantly less everywhere. But with the exception of the south coast, one can hardly speak of a “dry season” even then. Papua New Guinea is a very rainy country. In the lowlands it is the driest with “only” 1,200 mm per year; in the mountains up to 6,000 mm are possible.

Best time to travel to Papua New Guinea

To avoid the rainy season, vacationers should visit Papua New Guinea between June and September. Then it is sunny and sometimes even dry on the coast. In the humid mountain regions, the heavy rain showers decrease significantly in summer, even if even then it never becomes completely dry. The temperatures are a pleasant 26 to 27 ° C.

If you visit between December and April, however, abundant tropical rainfalls and hurricanes will make getting around almost impossible and will definitely spoil your holiday fun.
