Being in the Southern Hemisphere, New Zealand's seasons are opposite from what most of the world experiences in the North.  Auckland is located in the north of the North Island, and although it does experience all four seasons, it never gets very cold.  During the winter months (June-August) the average temperature in Auckland is someplace in the low to mid 50's F, while in the summer (December-March) it is known to get quite hot, averaging in the 90's.  Visitors to Auckland from the Northern Hemisphere generally prefer coming during their winter, Auckland's summer, to enjoy the warm weather and the seaside.  For an up to date weather forecast, including any severe weather information for Auckland, visit New Zealand MetService - Auckland Weather Info
