Winter had two halves

12:00 pm on 5 September 2012

Winter was a season of two halves. NIWA (the National Institute of Water & Atmospheric Science) says that while the first half was colder than usual, the second was unusually mild.

Southwest winds dominated the first half, sending temperatures plummeting, but a change to more frequent northeast winds in July brought warmer and wetter weather to many areas.

Overall, it was warmer than usual in the west and south of the South Island, as well as in Nelson, parts of Northland and around Ohakune, with temperatures between 0.5 - 1.2 degrees Celsius above the winter average.

Temperatures were average elsewhere.

In the South Island, it was extremely wet in northern and eastern areas, and unusually dry in western and southern regions.

Rainfall in the North Island was generally average except in western Bay of Plenty and the Wairarapa coast, which were wetter than usual.
