A SWELTERING WEEK BUT MORE THAN A SPLASH OF RAIN FOR SOME
It’s been a warm week for most of New Zealand with a sweltering 35.0C measured at Dunedin airport during Tuesday
afternoon - the hottest on record since the station was established in 1972.
“The heat at the start of the week, particularly over eastern regions of the South Island, was a precursor to a low
which attempted to cross the country from mid-week.” April Clark MetService Meteorologist said.
Northerly winds ahead of the low and clear sunny days on Monday and Tuesday meant temperatures rose to over 30C for many
eastern inland areas from Blenheim through to Southland.
“But the beach weather couldn’t last forever” lamented Clark, “The low eventually brought cloud and a period of rain to
most of the country from late Wednesday, though temperatures only cooled slightly as continued northerly winds kept the
feed of subtropical air over the two Islands going”
Parts of the upper North Island and the west of the South Island bore the brunt of the rain with 333mm of rain recorded
in 24 hours about the western ranges of Nelson. Of the towns, Kaitaia and Inglewood also saw a good dose of rain
measuring 49.9mm and 42.0mm respectively over the course of a day.
The low weakened and moved away to the northwest on Saturday as it stalled against a broad high to the east of New
Zealand. This allowed the sun and hot temperatures to return for most parts over the weekend.
For the coming week, the low will remain over the Tasman Sea, directing more warm air over the country. This is forecast
to bring rain to the North Island on Monday, this gives way to finer conditions later in the week though showers with
thunderstorms are possible on Tuesday. The South Island is looking to keep mostly dry on the first day of the working
week, but a few heavy showers are expected over inland areas and a front in the far south brings rain to Fiordland.
