The weather patterns appear to be turning in favour of farmers but it may come at a cost for those who can’t sleep due to high humidity.

Last night a number of northern regions reached saturation point with 100% humidity being recorded from Auckland to Whangarei.

Head weather analyst Philip Duncan says the run of humid weather isn’t likely to go away soon.  “We may see a break this weekend when the high in the Tasman Sea spreads over the country bringing drier southerlies otherwise it’s going to be hot and humid until Friday then starting all over again next week”.

He expects over night lows to remain in the low 20s for the rest of the working week, with little in the way of cooling breezes.

Mr Duncan says the tropics north of New Zealand have been very active lately and it was just a matter of time before the high over New Zealand gave way.  “We’ve been saying this for a few weeks now – the tropics are active, the highs over New Zealand aren’t dominating like last year, rain will arrive soon”.

“The Coral Sea is an area that we watch closely – when large lows form there they can often track south east towards New Zealand.  We’re expecting a low to drift down next week perhaps bringing more rain to the country”.

Recent flooding in Queensland has been caused by lows in the Coral Sea being blocked by a large high in the Tasman Sea – the same high responsible for bringing record breaking heat to Australia and New Zealand recently.

WeatherWatch.co.nz says much of the North Island will continue to have humidity in the 80 and 90% range until about Friday. 

With more rain expected on Thursday farmers and those on rain water tanks will be pleased with the recent forecast.
