Auckland weather is basically a mood ring. You wake up to glorious sunshine, grab a coffee in Britomart, and by the time you’ve walked three blocks, you’re dodging a sideways downpour. It’s the "City of Sails," but sometimes it feels more like the "City of Four Seasons in Four Minutes."
Honestly, if you're looking at the sky right now and thinking it looks "settled," you've already been fooled.
Today, Saturday, January 17, 2026, the vibe is a bit of a mixed bag. We’re sitting at a high of 26°C, which sounds like peak summer perfection on paper. And for most of the morning, it actually has been. But there's a catch. There's always a catch in Auckland.
The Reality of Auckland New Zealand Weather Today
Right now, the humidity is hanging around 83%. That’s the kind of thick, sticky air that makes your hair do things you didn't give it permission to do. While the morning started off mainly fine with just a bit of lingering cloud, the afternoon is bringing in those classic Auckland "surprises."
MetService has been tracking a few showers developing this afternoon. It’s not a total washout—don't cancel your BBQ just yet—but you’ll want to keep an eye on the horizon. The wind is currently coming from the southwest, but it's expected to pull a classic Kiwi U-turn and swing around to the east by this evening.

Why the "Burn" is Real
The UV index is hitting a 3 today. Now, that might sound low compared to the "Extreme" levels we usually see in mid-January, but don't let the clouds fool you. In New Zealand, the sun doesn't just tan; it cooks.
- UV Protection Window: 10:00 AM to 5:10 PM.
- The Risk: Even with the cloud cover, you can get scorched in about 15 minutes.
- The Solution: Just put on the sunscreen. Seriously.
I’ve seen tourists walking around Mission Bay looking like boiled lobsters because they thought "overcast" meant "safe." It doesn't. Not here.
What’s Actually Happening North of the Bridge?
If you're planning on heading up to Northland or even just the northern reaches of the Auckland region, things get a bit more dramatic. There’s been some pretty intense flooding up in Northland today. Communities like Ōakura and Helena Bay have actually been cut off by slips and rising water.
Auckland itself is currently under a Yellow Heavy Rain Watch until 1:00 PM. While the worst of the "orange warning" stuff is staying further north, we’re still getting the leftovers. We're talking peak rain rates of 15 to 25mm an hour in some spots.

If you’re driving, be careful. Surface flooding on the motorway is basically an Auckland tradition at this point, but that doesn't make it any less sketchy when your tires lose grip.
The Wind Factor
The wind speed is sitting at about 18 mph (around 29 km/h) from the southeast. It’s enough to blow your umbrella inside out, which is why most locals don't even bother with them. A decent raincoat is the only way to survive a walk down Queen Street when the wind picks up.
What to Wear (The Auckland Strategy)
Layers. That’s the secret.
You need a base layer—something breathable like cotton or merino—because when that 26°C hits with the humidity, you’re going to sweat. But you also need a waterproof shell.

- Morning: Light t-shirt and shorts.
- Afternoon: Keep the raincoat in your bag for those incoming showers.
- Evening: A light sweater or hoodie. When the wind turns easterly tonight, it'll bring a bit of a chill with it.
Tomorrow: A Quick Look Ahead
If you’re hoping for a better beach day tomorrow, Sunday, January 18, it’s looking a bit cooler. We're expecting a high of 23°C and a low of 17°C. It’ll be partly cloudy with a "chance" of a shower (which in Auckland usually means it will rain for exactly six minutes while you're trying to unload the car).
The southeasterlies are expected to become strong at night, so if you've got loose patio furniture, maybe tuck it away before you go to bed.
Actionable Advice for Your Saturday
- Check the Radar: Don't trust the window. Use the MetService app or NIWA's live radar before you head out for a hike or a boat trip.
- Avoid the Water: After heavy rain like this, Auckland's beaches often have wastewater overflows. Check the Safeswim website before you dive into the Waitematā.
- Drive for the Conditions: If you hit a downpour, slow down. Those North Shore slips aren't a joke, and visibility can drop to near-zero in seconds.
Auckland weather isn't something you "predict" as much as something you "negotiate" with. Pack your sunnies, grab your raincoat, and just roll with it.
Next Steps:
Check the Safeswim status for your local beach before heading out, and ensure your MetService alerts are turned on for any updates to the heavy rain watch.
