Cooler days ahead after a weekend of warm weather
Many across the country enjoyed an unseasonably warm and settled weekend, with a number of places in the east of the
South Island and lower North Island reaching the early 30s. However, the west of the South Island was cooler and wetter,
with Milford Sound recording over 200mm during the weekend. This is set to change in the latter half of this week, as a
strong cold southerly change sweeps northwards.
The warm temperatures continue into the week for the North Island and top of the South Island, with a number of places
in Wairarapa and Hawke’s Bay expected to reach 30 degrees today.
The first cold front moves up the South Island today, bringing some heavy rain to Westland, and strong northwest winds
to Hawke’s Bay as it moves onto the North Island on Tuesday. However, the coldest air accompanies the second cold front,
which moves up the country on Thursday.
Strong northwesterly winds are expected ahead of this front on Thursday, with severe gales possible in exposed places in
the eastern South Island and lower North Island. These are followed by a strong southerly change, which brings colder
air straight up from the Southern Ocean. Northern New Zealand won’t feel the temperature change quite so much, but
everywhere else will feel significantly colder. The coldest areas will be the far south and Otago, where daytime
maximums will only reach the mid to late teens, and drop down to single digits at night. The strong southerly flow will
also bring large swell of four to five metres to southern and eastern coasts.
Western parts of the South Island will bear the brunt of the rain accompanying the second cold front, with accumulations
likely to reach warning amounts there. Elsewhere just expect a few showers as the front sweeps north.
However, behind this change a ridge of high pressure builds which should bring fine weather across much of the country
over the weekend.
