The climate of South Island (New Zealand)
South Island is the lower half of New Zealand. This island has a varied landscape. This makes the climate varied as well. The Southern Alps mountain range lies in the middle of the island. This magnificent mountain range almost splits the island in two. This is a true paradise for hikers and climbers. It has beautiful summits such as Mount Cook, glaciers, lakes, rivers and craggy fjords. The landscape is truly magnificent. In the coastal areas where temperatures are higher many beautiful beaches and areas can be found. Abundant unique plant and animal life can be enjoyed here. The South Island has the least inhabitants of the two islands. It also has the most national parks such as Kahurangi National Park. Of all the species that live in New Zealand 50% can be found in this national park with its pristine primary forests. Because of the high mountain range there is more precipitation in the eastern part than in the western part. South Islandís climate is equal to the climate in the Netherlands. However, because it is situated in the middle of The Pacific weather is much more influenced by the sea. Because of the influence of the wind weather can change dramatically in the course of one day.
