The weather has been unseasonably changeable for January,
according to Queenstown meteorologist David Crow. Summer had
not been bad at the start, but January saw a preponderance of
low-pressure centres to the east of the South Island and
fairly slow-moving anticyclones in the western Tasman Sea, he
''Between the two, there's been quite a cool southwesterley
airstream blowing for quite a while over the eastern Tasman
and New Zealand and it's incorporated and there's been some
fairly slow-moving fronts over us and they've been giving us
fairly extensive rain.
''The rainfall has been about half as much again as we would
normally have for the whole month and we're only halfway
through the month.''
The average temperature in December was 1.5degC above the
normal of 14.8degC. The notable high of 32degC on January 5
beat the Christmas Day high of 30.9degC. Mr Crow said
Queenstown normally experienced three summer days of more
''I think overall this month will finish off average for
temperatures,'' he said.
The top of the North Island had been enjoying finer weather
than the Wakatipu, but elsewhere in New Zealand the
conditions had been about the same, or worse, this summer.
''For the rest of this month, we're going to be rather cool.
Temperatures slightly below the average of 15.9degC and ...
wet. We should normally be experiencing high-20s at this time
of the year.''
A fast-moving ridge should lead to relatively mild weather
today, but Saturday afternoon was not looking good, with cool
conditions, southwesterlies and rain expected, Mr Crow said.
The temperature would be lucky to get to 15degC tomorrow, but
Sunday and Monday should improve.
''February is looking more seasonal, with light westerly
winds and warmer temperatures again.''
