At the bottom of the Southern Hemisphere, the seasons in New Zealand are reversed from what most of us are accustomed to. Summer runs roughly from December to March, with Christmas through January considered peak season. Snowfields on both islands lure skiers and snowboarders, making New Zealand a popular winter destination as well. During the shoulder seasons, the crowds die down. The weather on the North Island, especially around Auckland, is considered mild and temperate, making it a nice destination year-round.
