🌼 Our Spring 2026 Outlook is here!

El Niño is expected to have a strong influence on New Zealand's climate over the next three months.

💧 Rainfall is very likely to be above normal in the western and southern South Island, while drier-than-normal or normal conditions are more likely across many other parts of the country.

🌡️ Temperatures are also expected to lean warmer than average for much of Aotearoa this spring.

💨 Wind will be another feature to watch. While spring is typically a windy season, westerly winds are expected to be stronger and more frequent than usual across much of the country.

🌼 Spring begins Tuesday, but winter isn't quite done with us yet.

Many parts of New Zealand will wake to a chilly start, especially across the South Island, where temperatures will feel more like winter than the first day of spring.

🌬️ Gusty southwesterly winds will continue through the day before gradually easing by evening for most areas.

🌤️ The North Island is expected to be mostly dry, while the South Island will see some showers accompanied by the brisk winds. The good news? No widespread heavy rain is on the cards for Tuesday.

Keep the extra layer handy if you're heading out early!

❄ So much for (meteorological) winter coming to an end. ❄

Snow levels will lower over the South Island, with the higher terrain experiencing the most snowfall.

Road conditions will be impacted, especially through the various passes. Best to check road conditions with NZ Transport Agency Waka Kotahi.

Stay on top of the forecast with MetService New Zealand.

☔ Keep the rain gear handy, New Zealand!

Both islands are set for unsettled weather this weekend. Across the South Island, southwesterly winds will dominate, with passing fronts bringing rounds of rain and showers, especially in the west where the wettest conditions are expected.

Meanwhile, the North Island will see rain spread across many areas from Friday night, with isolated heavy downpours possible through Saturday as a slow-moving low lingers nearby.

Snow clears out so what's next for the weekend?

🌫️ A foggy start for Auckland!

Many Aucklanders woke up to widespread fog this morning, with reduced visibility causing travel delays across the region.

The setup was ideal for fog formation across the upper North Island, thanks to a moist airmass, mainly clear overnight skies, and very light winds. At times, the fog became quite dense before gradually lifting by mid-morning.

☀️ The good news? The fog cleared away to reveal beautiful blue skies across the City of Sails. Check out the timelapse below to see the transformation!
