A "monster" high forecast to hit New Zealand in mid-January
could put an end to recent spring-like weather.
Unpredictable, messy conditions are set to continue through
early January, but the long-awaited summer is in sight, said
WeatherWatch head analyst Philip Duncan.
The weather in Dunedin would be a bit unsettled to start with
- windy hotter days and windy colder days with some wet days
in the mix.
"But around the 10th onwards Dunedin may become quite hot and
sunny - summerlike even!" he commented on the WeatherWatch website.
There would be showers today in Auckland, but the rest of the
week was looking mostly dry, he said.
The second week of January would see "fickle" weather in
Auckland, but a huge high arriving the following week would
look "a lot more like summer".
"The further north you go, the better the weather's going to
be in January," Mr Duncan said.
Spring-like weather has peppered the country with wind and
showers every few days for the last few months.
"For the final two months of 2013 we've seen very little in
the way of big, settled, highs.
"This was great for farmers who desperately needed rain, but
now holidaymakers desperately want the sun."
Signs of summer were now finally on their way, he said.
"We see a monster of a high pressure system south of
Australia in the first half of January and we expect this
giant anticyclone to slowly drift towards New Zealand by the
end of week two," Mr Duncan said.
While the weather would settle down with the high, it
wouldn't be summer in New Zealand without the threat of a
tropical storm, Mr Duncan said.
Long-range forecasts showed a tropical storm that could drift
towards New Zealand in the second week of January.
However, the incoming high from Australia could push it back
out into the Pacific Ocean, WeatherWatch predicted.
MetService meteorologist Daniel Corbett said the first week
of January would be "fast and furious" across the country.
"The raincoat is going to get a bit of use unfortunately ...
until we get a decent high."
January temperatures would average in the low- to mid-20s in
most places, he said.
