Our early New Zealand Snow Forecast 2026 outlook points toward a more active ski season, with El Niño patterns increasing the chances of southerly storms and colder temperatures
While a long-range snow forecast 2026 is never guaranteed in New Zealand, the early weather data is pointing toward a potentially strong winter for the lower south-west of the South Island.
South Island
- Colder temperatures likely
- Southerly storm potential
- Wetter outlook
North Island
- Possible warmer temperatures
- Mixed snowfall
- Drier weather risk
There is about a 65% chance for El Niño conditions to emerge over the forecast period (May - July 2026).
Right now, the developing El Niño pattern appears likely to favour the South Island more than the North Island
The upper North Island could trend drier through winter, while the lower South Island and Southern Alps may see more regular cold southerly systems pushing through during the ski season.
If that setup develops, it could create one of those classic New Zealand winters where storms roll through, temperatures drop quickly, and large high-pressure systems follow behind to lock the cold in. For skiers and snowboarders, that’s usually the pattern you want to see – snow, bluebird days, then freezing nights helping preserve the snowpack.
Based on the current weather models and climate outlooks, the feeling is that the South Island could see a colder and more active winter than recent years.
That doesn’t necessarily mean huge snowfall every week, but it may support more consistent snowmaking conditions and regular southerly top-ups across many ski areas. The North Island should see some of the storm activity as it rolls up the country – especially Tūroa, located on the southern face of Mt Ruapehu.
Of course, this is New Zealand. One storm can change an entire season, and one warm month can undo it just as quickly
But if the current patterns hold, the early signs are at least pointing toward a promising South Island winter for 2026.
Well keep you posted on updates.
