Honestly, if you've lived in Auckland for more than five minutes, you know the drill. You wake up to a brilliant blue sky, plan a beach day at Mission Bay, and by 2:00 PM you’re sprinting for the car while a tropical downpour tries to drown your fish and chips. It's the classic "four seasons in one day" trope, but right now, looking at the 10 day weather forecast auckland, things are getting a bit more complicated than just a stray shower.
We’re currently sitting in that sticky mid-January pocket where the humidity makes your hair double in size and the "door to the tropics" is standing wide open.
What's actually happening over the next 10 days?
Basically, we're looking at a split personality week. The first half is, frankly, pretty damp. We’ve got a heavy rain watch in place right now (Sunday, January 18) with a high of 67°F (around 19°C) and an 85% chance of rain. It’s not just a drizzle either; MetService is flagging possible heavy falls. If you were planning on doing laundry today, just don’t. It’s a "wet all day" situation.
Monday and Tuesday (January 19–20) don't exactly clear things up. You've got highs of 70°F and 69°F respectively. Expect a lot of "mostly cloudy" vibes with light rain creeping in, especially on Tuesday when the humidity hits 83%. It's that kind of weather where you aren't sure if you’re sweating or if it’s actually raining.
The Mid-Week Slog
Wednesday and Thursday (January 21–22) keep the moisture coming. Thursday looks particularly rough with "heavy rain" forecasted and a high of 70°F. Wind speeds are picking up too, hitting about 21 mph from the northwest.
But then—and this is the part you'll want to circle—things start to shift.
The Light at the End of the Tunnel
If you can survive the soggy start, the back half of this 10-day stretch actually looks like summer.
- Friday, January 23: The clouds start to break. We’re looking at 71°F and partly sunny skies.
- The Weekend (Jan 24–25): Sunday the 25th is the winner here. It’s forecast to be a straight-up sunny day with a high of 69°F. The UV index jumps to a 9, which is "burn you in ten minutes" territory, so break out the SPF 50.
- Next Week (Jan 26–28): We settle into a nice groove of partly sunny days and highs reaching 72°F.
Why is it so humid lately?
You can thank a rapidly weakening La Niña for the current stickiness. According to NIWA’s latest seasonal outlook, there's a 65% chance of above-average temperatures for Auckland through March. Because the sea surface temperatures around New Zealand are warmer than usual, the air holds more moisture. That’s why we’re seeing these tropical "moisture intrusions" that turn a normal afternoon into a sauna.
Meteorologist Nava Fedaeff recently pointed out that with the tropical cyclone season active, we can't really rule out these systems drifting down and delivering those random heavy dumps of rain. It’s why the 10 day weather forecast auckland looks like a seesaw right now—one day it’s a tropical depression, the next it’s a pristine Pacific summer day.
Quick Survival Tips for the Week
Don't trust the morning sun. Seriously. If you're heading out, bring a light waterproof shell. It sounds like such a "dad" advice, but with 70% to 80% humidity and sudden rain chances, you'll regret the cotton hoodie.
Keep an eye on the UV levels starting Friday. We’ve been stuck under cloud cover, so it’s easy to forget how bitey the New Zealand sun is. When that sky clears on Sunday the 25th, the UV index of 9 is no joke.

Also, for the gardeners: soil moisture levels in Auckland have been leaning toward the drier side lately despite these bursts of rain. If you've got veggies, they'll appreciate the drink this week, but keep an eye on the drainage because Thursday’s heavy rain could lead to some pooling if your soil is packed tight.
The Takeaway
The first five days of this 10-day block are for indoor errands, catching up on Netflix, and pretending you enjoy the sound of rain on a tin roof. The final five days? That’s your window. Get the BBQ ready, hit the coast, and enjoy the sun while the "tropical door" is momentarily swung shut.
Next Steps for You:
Check the MetService "rain radar" about an hour before you head out. In this kind of "easterly flow" setup, the rain bands move in specific lines—it might be pouring in Pononby while it's bone-dry in Albany. If you're planning a walk, Sunday the 25th is your gold-medal day for outdoor activities.
