New Zealand climate in August 2006
August rainfall was well above normal in southern parts of the North Island, including Wanganui, Kapiti, Wellington, Wairarapa, and also around Christchurch. In contrast, most of the rest of the South Island was drier than normal.
Air temperatures were near average in most regions, with both warm and cool spots in Otago, and cool conditions in the west of Northland. The national average temperature of 8.8°C was 0.2°C above the 1971–2000 normal.

June 2006 to August 2006: the climate we predicted and what happened
The North Island was drier in the north and wetter in the south and east than was predicted. Mid to north Canterbury received normal to above normal rain as predicted, but elsewhere in the South Island it was drier than expected.
Air temperatures were mostly lower than expected, apart from near normal temperatures, as predicted, in parts of the east and south of the North Island, and the east and southwest of the South Island.
North Island stream flows were normal or below normal in the north and above normal elsewhere. South Island stream flows were normal to above normal, as predicted, in Canterbury and below normal elsewhere.
