A cold southerly change arriving for the end of September will ensure October 1st will be colder in most main centres and regions of New Zealand, says WeatherWatch.co.nz.

“The typical spring ups and downs have arrived” says head forecaster Philip Duncan. “One day it’s a northerly flow from the sub-tropics, the next day a colder southerly from the Southern Ocean area”.

The classic spring weather isn’t looking too problematic next week with another high pressure belt moving in following on from the colder weekend. Drier weather with high pressure will also move in. But before this happens a low in the Tasman Sea this weekend will bring more rain (and wind) to the North Island. For some areas further rain will be welcome as we approach the drier months of summer – but for others (like saturated Hawke’s Bay) the forecast of more rain is not what everyone wants to hear following recent rain and slips.

Northerlies towards the end of the week will push temperatures for many regions into the late teens, even the low 20s. By Saturday some places will have daytime highs more than 10 degrees colder/lower than they were this week.
