It was dry, warm, and sunny on the South Island’s west coast, while eastern South Island regions experienced cool, cloudy conditions. The lower North Island was wet, while much of the upper half was drier than normal.
Some parts of the lower North Island, including Taranaki and Hawke’s Bay, had double their normal rainfall. An isolated extreme rainfall event on 21 February brought more than three times normal February rainfall to Great Barrier Island. Above average rainfall also occurred in Coromandel, central Hawke’s Bay, the central North Island volcanic plateau, north Canterbury, and coastal Southland.
In contrast rainfall was less than half normal in Waikato, western Bay of Plenty, Taupo, and parts of Northland and Central Otago. Rainfall was down 25% from normal in Auckland, eastern Bay of Plenty, south Westland, and Fiordland.
