New Zealand climate in October 2005
Contrasting rainfall patterns between the North and South Islands were a feature of the October climate. Gisborne, Hawke’s Bay, Auckland, and Waikato were extremely wet, while much of the South Island was very dry.
Air temperatures were above average in the northern half of the North Island, and below average in many other regions, especially parts of Marlborough and Canterbury. The national average temperature of 12.0 °C was 0.1 °C below normal.
