MetService says that while Christmas Day is shaping up to be mostly good and warm in northern and central New Zealand, southerly winds are forecast to bring unstable and cooler conditions further south.
These cold southerly winds swept across the rest of the country over the weekend, bringing rain or showers to eastern areas and unusually cold temperatures to southern and central New Zealand.
“As we approach Christmas, a low pressure depression moves across the country today (Wednesday) and Thursday, bringing rain to much of southern and central New Zealand, in addition to a period of strong winds from the north to the exposed parts of central New Zealand.
“Adverse weather alerts and advisories remain in effect here. “
Although northern New Zealand is expected to be fairly cloudy with rain or downpours in the lead up to Christmas, temperatures will remain warm and many places will hit the mid-twenties.
“For most of us, the weather leading up to Christmas Day is not ideal for completing that last yard job or tidying up outside, and people with kids on vacation will need to plan some indoor activities,” says the meteorologist from MetService Peter Little.
A south-southwest flow covers much of the country on Christmas Day, with a generally stable and warm weather forecast for northern and central New Zealand.
Yet another channel moves south to New Zealand from the Tasman Sea, bringing rain and cooler temperatures, especially in the eastern areas.
For Christmas Day, mostly sunny skies are forecast over Auckland, Hamilton and Tauranga, with daytime temperatures reaching into the mid-twenties.
However, the southwesterly breeze will be noticeable in exposed locations, especially Auckland. Overcast periods, moribund southerly winds and a high of 19 ° C are forecast for Wellington.
For Christchurch and Dunedin, the skies are expected to be mostly cloudy with a few showers, with the easterly breeze keeping the maximum at just 16 ° C.
“Although the forecast is dry for much of the country on Christmas Day, there will be some places that will receive rain or showers, especially in the south. If you plan to have your Christmas meal outdoors, it would be wise to check your forecast at metservice.com to see if you need a backup plan. “
On Boxing Day, the trough moves over the rest of the country, followed by cooler winds from the south. These southerly winds bring rain or showers to mainly eastern areas at the weekend, and unusually cold temperatures to many places.
“Snow is forecast up to 1,000 meters over the South Island this weekend, and a maximum temperature of just 13 ° C is forecast for Ashburton on Saturday, which is around 8 ° C below average for this time of year. In the capital, maximum temperatures of 14 ° C and strong south winds are forecast for Sunday, “adds Little.
“Hopefully the conditions won’t ruin your plans for the next few days, but whatever the weather, everyone at MetService wishes you a Merry Christmas.”
