You’re staring at your phone, and there it is—a yellow banner from MetService. A New Zealand strong wind watch. For a lot of us, it’s basically background noise at this point. We live in the Roaring Forties, after all. If the trampolines aren’t airborne, is it even Tuesday?
But here’s the thing: people often treat a "watch" like a "warning," or worse, they ignore it completely because it isn't "orange" yet. That’s a mistake that ends up costing people their fences, their windshields, or a very expensive call to their insurance broker. Right now, as we navigate this weird January 2026 weather pattern where tropical lows are flirting with our coastline while the South Island swelters, understanding these alerts is actually pretty critical.
Is a New Zealand strong wind watch actually a big deal?
Basically, a watch is a "heads up." It’s MetService saying, "Hey, the ingredients for a mess are all in the bowl, but we aren't 100% sure yet if it's going to bake into a disaster." Specifically, they issue a watch when there’s a possibility that winds might reach "warning" criteria—which usually means sustained speeds of 90 km/h or gusts over 110 km/h—within the next 24 to 72 hours.
It's the yellow light before the red.
Honestly, the nuance matters. If you see a watch for the Wellington region or the Marlborough Sounds, you’ve gotta remember how the local topography works. Wind gets funneled through the Cook Strait like a garden hose being squeezed. A "watch" in the capital can feel like a full-blown gale in the suburbs of Karori or Miramar. Just last week, on January 11, we saw over 80 flights cancelled at Wellington Airport because of gusts that caught people off guard. That wasn't even a record-breaking storm; it was just "unsettled" weather doing what it does best.
The difference between a watch and a warning
- Watch (Yellow): It might happen. Keep an eye out. Secure the light stuff.
- Warning (Orange): It’s happening or definitely coming. Secure the heavy stuff. Tie down the boat.
- Red Warning: This is the big one. Significant impact, potential danger to life, and likely power outages.
Why January 2026 is feeling so chaotic
If you feel like the weather has been bipolar lately, you aren't imagining it. We are currently in a transition phase. NIWA and MetService have been tracking a weakening La Niña, which usually means more "neutral" conditions. But "neutral" doesn't mean "calm."

Right now, we’ve got a massive high-pressure system sitting over the South Island, which is why places like Christchurch and Central Otago have been hitting 30°C plus. But that high pressure is fighting against a "disturbed easterly flow" coming off the Tasman. When you have high pressure and low pressure grinding against each other like tectonic plates, you get wind. Lots of it.
For the North Island—specifically Northland, Auckland, and the Coromandel—the risk isn't just a straight-line gale. It’s the "tropical moisture intrusions." These are those sticky, humid systems that bring heavy rain and sudden, violent squalls. A New Zealand strong wind watch in this context often means "be ready for a thunderstorm that could knock a tree onto your power lines."
What most people get wrong about the "Watch"
The biggest misconception? Thinking a watch means "it's not that bad yet."
Actually, for a lot of boaties and high-sided vehicle drivers, a watch is already "bad enough." If you're towing a caravan over the Remutaka Hill or the Desert Road, a 70 km/h gust (which might only trigger a watch or even just an advisory) is plenty to flip you.
I spoke with a local linesman during the last blow in Taranaki, and he pointed out that it’s often the "minor" wind events following a period of heavy rain that do the most damage. The soil gets saturated, the roots get loose, and then even a "watch-level" gust can tip a mature pine right onto a transformer.

Real-world impacts we're seeing right now
Look at the stats from the last few days. We’ve seen:
- Aviation chaos: 50+ Air New Zealand cancellations in a single day due to crosswinds.
- Wildfire risk: This is the scary one. In the South Island, especially North Canterbury, the wind isn't just a nuisance—it’s a blowtorch. When FENZ (Fire and Emergency NZ) sees a strong wind watch combined with 30°C heat, they go into high alert. The wind dries out the "fine fuels" (grass and scrub) and carries sparks for kilometers.
- Marine hazards: Puysegur Point and the far south have been seeing "very rough" seas with 35-knot southerlies. If you’re in a 6-meter tinnie, a "watch" is your signal to stay at the boat ramp.
How to actually handle a strong wind watch
Don't just read the alert and go back to scrolling. If you're in an area under a watch, there are three things that take five minutes but save hours of grief later.
First, check the "tramp factor." Every year, New Zealand insurance companies pay out thousands for "Unidentified Flying Trampolines." If it’s not pegged down with proper anchors, flip it over or tie it to a fence post. Same goes for those expensive cantilever umbrellas.
Second, think about your travel. If you're planned to fly through Wellington or Napier, check the arrivals board before you leave for the airport. Airlines like Air New Zealand often offer flexibility during these watches because they know the 110 km/h threshold is just a number—safety is about the gust angle.
Third, and this is for the North Island folks right now: clear your gutters. When a strong wind watch is paired with those tropical lows we’re seeing, the wind rips leaves off the trees and plasters them over your drains. The wind doesn't flood your house, but the blocked downpipe certainly will.

Actionable steps for the next 48 hours
If you see that yellow icon on the MetService map today, here is your checklist.
Secure the perimeter. Walk around the yard. Anything that can be picked up by a 90 km/h gust becomes a projectile. This includes plastic chairs, empty potting mix bags, and the kids' swing set.
Charge the tech. Wind watches often lead to "flickery" power. In rural spots like the Wairarapa or Taihape, a branch on a line can take out power for a whole valley. Get your phone and power banks to 100% now.
Check your commute. Bridges like the Auckland Harbour Bridge or the Tauranga Maunganui bridge often have speed restrictions or lane closures during high winds. Give yourself an extra 20 minutes.
Don't be "that guy" on the water. If you're planning to head out into the Hauraki Gulf or the Marlborough Sounds, look at the "Wind Gust" layer on an app like Windy. The "average" wind might look fine at 15 knots, but the gusts in a watch could be double that.
A New Zealand strong wind watch isn't a reason to panic, but it is a reason to be smart. In a country where the weather can change before you've finished your flat white, being prepared is just part of the deal. Keep an eye on the MetService updates—they refresh them every few hours—and if that yellow turns to orange, make sure you're already inside with the windows shut.
