The first week of April may well be a rough one across New Zealand weatherwise predicts WeatherWatch.co.nz.
Westerlies are picking up strength while lows in the Southern Ocean continue to grow and move closer towards us as the build up to winter’s aggressive weather pattern begins.
Next Wednesday / ECMWF
Next week a large low is predicted to build east of Canterbury and may linger for the entire week – potentially driving in the first belt of sustained heavy rain for Christchurch this year. While it will be helpful in removing liquefaction and for collecting drinking water it may cause further utility issues, particularly with storm water.
Wednesday, Thursday and Friday of next week see strong, cold, winds from the south or south east right along southern and eastern coastlines from Southland to Wairarapa.
However rain or showers could affect Christchurch and much of eastern New Zealand as early as Monday and last right through until next Saturday.
For northern and western New Zealand rain isn’t expected to be as heavy and widespread however a number of days next week look unsettled with strong winds mostly from the westerly quarter and several fronts.
Snow is also being predicted in the South Island by WeatherWatch.co.nz, possibly falling to the lowest levels so far this year although it is not expected to affect travel plans at this stage or affect any main centres.
Highs around the middle of next week in Southland, coastal Otago and Canterbury may not even reach the teens.
A new Sub-tropical low?
Meanwhile long range computer models used by WeatherWatch.co.nz are now picking a new tropical low in the Coral Sea at the end of next week, with it moving our way.
The models have been consistent for 48 hours however any predictions a week out can change significantly.
Latest models do not show this low as a tropical cyclone however any sub-tropical low can bring flooding rains – so we’ll keep you posted.

as you know we had a la nina during the summer season(making it hotter/humid than normal).. so does that mean it will be even colder than normal during winter?

Thanks for the question – and no, it doesn’t. In fact if La Nina continues on into winter it would mean a milder winter with potentially more snow (due to higher moisture levels).
At this stage NIWA believes La Nina will fade by the start/early winter.

Cyclone season runs until the end of Apri, although with a strong La Nina this year it may extend into May.

I dont think is the word your looking for, if we get lots of rain the tables will fill up and add more storm water etc.
But certainly will be a colder week with a first taste of winter, good time for thunderstorm chances too across the country so be ready to cover any late veges or fruit in the garden due to large hail.
Snow in early april isnt unheard of to low levels, in early april of 2005 i think it was brought snow to much of the lower south closing roads and making driving difficult.

Yeah good point bout the hail Jason. I just said to my partner that we will need to get some frost guard for our fruit trees soon. Some mornings have had that heavy chilly dew on the ground.
