SnowBrains Forecast: Windy Sunday Storm Targets New Zealand with Up to 30 cm

New Zealand’s snow forecast centers on a windy Sunday storm that could bring the deepest new snow to Canterbury and Ruapehu. Snow levels fall as the storm moves through, but severe wind and mixed precipitation early in the event could limit the payoff for skiers.

Snow already falling around Mt. Hutt and Porters tapers through Wednesday, while Ruapehu gets light snow showers. A smaller Friday wave brings a modest refresh to several South Island mountains before snow levels rise on Saturday. Porters has ended its season and Mount Dobson is closed, so their forecast totals describe mountain snowfall rather than lift-served skiing.

Models broadly agree on a stronger Sunday storm, though snowfall amounts vary by mountain. In Canterbury and around Queenstown, precipitation begins with relatively high snow levels, then turns colder and snowier as levels drop well below resort bases. The early snow will be dense, with better quality as temperatures fall, but gusts around 60-100 km/h could strip exposed terrain. Ruapehu faces the harshest phase: snow levels briefly rise into resort terrain and gusts could exceed 150 km/h before colder air arrives. Showers linger there into Monday and early Tuesday. With partial operations currently reported at Whakapapa and Turoa, Sunday’s wind makes lift access especially uncertain.

Confidence is strongest through Tuesday as the Sunday system clears. Another chance of snow appears around the following weekend, but the models differ on its timing and reach, so it is too early to count on a second substantial refresh. Treble Cone’s scheduled Sunday season finish also limits the prospect of lift-served turns there after the storm.
