Covering period of Tuesday 3rd - Sunday 8th June

Another bout of windy and wet weather is due to run across New Zealand this week followed by a wintry feeling weekend with cold temperatures across the country and even some snowfall for the South Island.

MetService is forecasting a broad area of rain to move across the country from west to east during Wednesday, with the heaviest rain expected in Taranaki Maunga and Tasman District where Heavy Rain Warnings have been issued. The rain and strong winds are the result of a rapidly deepening area of low pressure forming off the eastern coast of Australia and crossing the country.

MetService Meteorologist John Law says, “This week we see another visitor arriving from the Tasman Sea and it’s set to bring some active weather with it, but it’s not just the wind and rain we have to watch out for, with cold air rushing in behind this system it’s going to be a much colder end to the week.”

Heavy Rain Warnings have been issued for Bay of Plenty east of Whakatāne and inland Gisborne/Tairāwhiti, Tongariro National Park, Taranaki Maunga, the Tararua Range, Tasman District west of Motueka and Marlborough Ranges. Heavy Rain Watches have been issued for Northland, Auckland, Buller, Grey, Westland and Fiordland.

The rain on Wednesday is expected to be accompanied by thunderstorms in the northern and western parts of the North Island, with localised downpours, strong and gusty winds forecast. Strong Wind Watches have been issued for Northland, Auckland, Bay of Plenty, Gisborne, Taranaki, Wellington and Wairarapa.

Overnight Wednesday, the Canterbury High Country is likely to find rain turning to snow, especially across the higher parts of the region and impacting the higher roads and passes. A Heavy Snow Watch has been issued for the region, with heavy snow possible above 300 metres (or possibly lower).

“As we’ve turned into June the weather will be taking on a real wintry feel,” says Law. “On Wednesday, we’ll be expecting snow for some of the higher roads of the Canterbury region so take extra care and keep up with the latest forecasts as well as the latest road information from NZTA.”

Temperatures are set to tumble for the end of the week, with daytime highs struggling to get beyond the teens across the country.

“The second half of the week will be feeling very different to the first, as cold southwesterly winds sweep across New Zealand,” says Law. “The coldest spots will be found in Central Otago, where daytime temperatures for Wānaka and Alexandra are only likely to reach 3°C or 4°C this weekend.”

While snow is set to stay about the high country on Wednesday and Thursday, the colder air on Friday brings the potential of snow to lower areas of Canterbury. 

“Cold air and wintry showers will feature in the forecast for parts of the South Island on Friday, but the heaviest snow is expected over the highest parts of Canterbury overnight on Wednesday. Snow is likely to near sea level on Friday for Canterbury, Otago, Southland and Fiordland. While this snow is likely to be significant and may cause disruptions to travel, at this stage warning amounts are not expected,” Law concludes.
