Election Day 2017 Forecast


Most New Zealanders can be confident of a dry trip to the polling booth on Saturday, according to NIWA meteorologist Seth Carrier.

Mr Carrier says a high pressure centred north of Cape Reinga offers tranquil conditions and blue skies for Election Day. But with a departing storm off the East Cape and a decaying front moving into the South Island, rain in some places may have voters seeing red.

It’s pretty black and white in the North Island except for a few nuisance showers across Gisborne and Hawke’s Bay but these should taper off by midday. Gisborne will also be breezy.

During the afternoon a very weak front will arrive in the North Island, delivering a few light showers to keep things green in western and central areas, including Auckland, Hamilton, Taupo, and Wellington.

Election day in the South Island will be a bit more unsettled in places as a front moves onshore. In fact the morning will be showery across Southland, Otago, and Stewart Island, although these areas will see improving conditions in the afternoon. Scattered showers will also move along the West Coast, while Tasman, Nelson, and Marlborough will remain mostly dry.

Perhaps the best Election Day weather will be found in Canterbury, where it is expected to remain dry along with above average temperatures in the 15-18°C range.

In the Chatham Islands, the day will be typically showery and cool, with the temperature hovering around 12°C.
