You’ve heard the jokes. If you haven't, just stand on a street corner in New Zealand's capital for five minutes. You’ll see a businessman’s umbrella turn inside out, or a tourist trying to walk against a gust that looks like it belongs in a wind tunnel.
Wellingtonians don't just check the weather; they negotiate with it.
Right now, in mid-January 2026, the weather forecast Wellington New Zealand is serving up a classic "mixed bag" that would confuse anyone living in a more predictable climate. We’re currently seeing a bit of a tug-of-war between a weakening La Niña and some stubborn high-pressure systems sitting down by the South Island.
The result? It’s not just "sunny" or "rainy." It’s a complex dance of humidity, southerly busters, and those rare, world-class days where you wouldn't want to be anywhere else.
Why the Wellington Forecast is So Unpredictable
Geography is the culprit. Wellington sits right on the edge of the Cook Strait, a narrow gap between the North and South Islands. This creates a funnel effect—basically a giant natural wind pipe.
When you see a weather forecast Wellington New Zealand that says "breezy," you should probably double-check your hat.
The Southerly vs. The Northerly
Most of our weather comes from two directions. The Northerly is usually warmer, often gusty, and brings that "fine but windy" vibe. Then there’s the Southerly. This is the one that comes straight up from the Southern Ocean. It hits the city like a cold wall.
Even in the height of summer, a sudden shift to a southerly can drop the temperature from a pleasant 22°C to a shivering 13°C in less than an hour.
January 2026: The Tropical Twist
This year is a bit weirder than usual. NIWA (the National Institute of Water and Atmospheric Research) has been tracking "tropical moisture intrusions."
Basically, the door to the tropics is wide open.
While January is historically our driest month—averaging only about 80mm of rain—2026 is feeling "sticky." We’re seeing more humid nights where the temperature refuses to drop below 16°C. For a city built for the cold, this makes sleeping a bit of a nightmare.
- Current Highs: Hovering around 19°C to 21°C.
- UV Levels: Extreme. We’re talking "burn in 10 minutes" territory.
- Wind Speeds: Averaging 30-40 km/h, but gusts are hitting 60 km/h plus on the regular.
Honestly, the "real feel" is what matters here. A 20-degree day in Wellington feels like 25 in the sun but can feel like 15 the moment you step into the shade or the wind picks up.
Reading Between the Lines of the MetService App
If you're looking at the weather forecast Wellington New Zealand on your phone, don't just look at the little icon.
If it shows a sun with a cloud, but the wind icon shows a strong arrow, plan for the wind first. The "Chance of Precipitation" (PoP) is also famously tricky here. A 20% chance of rain in Wellington often means a short, sharp burst of horizontal drizzle that clears up before you can even find your raincoat.
The "Can't Beat it on a Good Day" Myth
Locals love to say "You can't beat Wellington on a good day." It’s a defensive mechanism. A "good day" means the wind has died down to a whisper, the harbor is like glass, and the sky is a deep, piercing blue.
In January 2026, we’ve had about four of those so far. The rest have been a battle of endurance.
Survival Tips for the Wellington Climate
You can spot a tourist because they’re carrying an umbrella. Don't be that person. An umbrella in Wellington is just a portable piece of twisted metal waiting to happen.
- The Merino Layer: Even in summer, keep a light wool layer in your bag.
- The Windbreaker: It doesn't need to be heavy; it just needs to stop the air from cutting through you.
- Sunscreen is Non-Negotiable: Because of the wind, you won't feel "hot," so you won't realize you're being fried by the ozone hole's proximity until it's too late.
- Anchor Your Belongings: If you’re dining outside at a cafe on Cuba Street, put your phone or a heavy object on your napkins.
What the Rest of the Summer Looks Like
Looking ahead through February and into March, the forecast suggests we might finally get some settled weather. Usually, March is actually the most consistent month in the capital. The "Roaring Forties" (the winds between 40 and 50 degrees latitude) tend to take a bit of a breather.

But for now, keep an eye on the southerlies. They are the true masters of the city.
To stay ahead of the changes, check the MetService radar every morning around 8:00 AM. That’s usually when the day’s true personality reveals itself. If you see clouds stacking up over the Rimutaka Range, the afternoon is probably going to be grey. If the South Island is visible and clear across the strait, you're in for a beauty.
Always have a Plan B for outdoor events. If you're planning a BBQ at Oriental Bay, have a spot cleared in the living room just in case. It’s the Wellington way.
Pack for three seasons every time you leave the house. Check the wind gusts, not just the temperature. Use a high-SPF sunscreen even when it looks overcast.
