The climate of Papua New Guinea is chiefly influenced by altitude and by the monsoons. The northwest or wet monsoon prevails from December to March, and the southeast or dry trade winds from May to October.
Papua New Guinea is one of the most heterogeneous nations in the world.There are hundreds of ethnic groups indigenous to Papua New Guinea, the majority being from the group known as Papuans, whose ancestors arrived in the New Guinea region tens of thousands of years ago. The other indigenous peoples are Austronesians, their ancestors having arrived in the region less than four thousand years ago.
In Papua New Guinea the old beliefs have blended with Christian beliefs that had been introduced in the last century, which now form unique traditions for this part of the world.
In the Trobriand Islands Good Friday is regarded as the most important religious event in the year. About mid-morning a large number of people gather for a service in the settlement of Losuia. The youth from the surrounding villages present musical and other items on an Easter theme at this service. After the service is over people divide into small groups of family and friends for feasts in various homes.
