Honestly, if you're looking at the 10 day weather auckland new zealand and seeing nothing but rain icons, don't cancel your ferry to Waiheke just yet. Auckland's weather is a bit of a local joke. We say you can experience four seasons in a single day, and frankly, that’s not even an exaggeration. It's Sunday, January 18, 2026, and right now, the city is sitting under a thick layer of clouds with a humidity level of 81%. It feels a bit sticky, doesn't it?
The current temperature is exactly 65°F. There's a 15 mph wind coming from the southeast, which is keeping things from feeling truly sweltering. But if you’re planning your week, you need to look closer at the nuance of these numbers.
The immediate outlook: Humidity and the "Real Feel"
Tomorrow, Monday, January 19, is looking like a bit of a transition day. We’re expecting a high of 73°F and a low of 64°F. While it'll be cloudy, the rain chance during the day is only 20%. It's that classic Auckland gray—not quite gloomy, just... there.
Then things get a little damp.
Tuesday and Wednesday (January 20-21) are bringing light rain back into the mix. We’re looking at highs of 71°F both days. The wind is going to pick up, too. By Wednesday, you’ll feel those 25 mph gusts coming from the east. It's not a storm, but it's enough to turn an umbrella inside out if you aren't careful.
The humidity is the real story here. Through Thursday, January 22, it’s going to hover between 76% and 88%. When the humidity hits 88% on Thursday, even a "comfortable" 73°F can feel a bit like walking through a warm soup.
What to expect for the rest of the week
By Friday, January 23, the sky finally decides to behave. We’ll see a jump in the UV index to 7, so if you’ve been slacking on the sunscreen because of the clouds, this is where you’ll get caught out.
- Friday, Jan 23: High of 74°F, partly sunny, winds shifting to the west at 15 mph.
- Saturday, Jan 24: High of 71°F with a 25% chance of showers.
- Sunday, Jan 25: This looks like the pick of the week. Mostly sunny with a high of 71°F and a whopping UV index of 10.
That Sunday UV index is no joke. In New Zealand, the sun is "vicious" (as the locals say) because of the thinner ozone layer here. You can literally get cooked in 15 minutes.
Looking further ahead: Late January trends
As we move into the following week, the temperatures start to climb. Monday, January 26, stays mild at 72°F, but by Wednesday, January 28, we’re hitting 76°F.

The wind patterns are shifting too. We’re moving from those gusty easterlies earlier in the week to much lighter 9-10 mph breezes from the southwest and west. This usually means the air feels a bit clearer and less heavy.
If you're tracking the 10 day weather auckland new zealand for an event, the late-week period from Friday the 23rd through Wednesday the 28th is significantly more stable than the first half of this forecast.
Expert packing: The Auckland survival kit
You’ve probably heard it before, but layering is your only hope. Since the temperatures are ranging from 61°F at night to 76°F during the day, a single heavy jacket is useless.
Basically, you want a very thin, breathable waterproof shell. Don't bother with a heavy raincoat; you'll just sweat. Cotton is okay, but quick-dry fabrics are better because of that persistent humidity.
Honestly, the most important thing you can carry is a high-SPF sunscreen and a hat. Even on those cloudy days like Monday and Tuesday where the UV index is only 3, the "burn time" can still surprise you if the clouds break for even thirty minutes.
Actionable insights for your trip:
- Dry your laundry early: On Monday, the MetService data suggests a 1-3 hour drying window in the morning before things get damp.
- Plan indoor activities for Wednesday/Thursday: These days have the highest precipitation chances (65%) and the strongest winds.
- Beach days: Target Sunday, January 25, or Tuesday, January 27. These have the lowest rain chances (10-15%) and the most sun.
- Watch the wind: If you're heading out on the Hauraki Gulf, Wednesday's 25 mph easterlies will make for a very choppy ride.
The reality is that Auckland in January is rarely "cold," but it is frequently "changeable." The forecast shows a mix of light rain and humidity followed by a beautiful, clear stretch. Just keep that light jacket handy and don't let a 35% rain chance ruin your plans—it usually passes as quickly as it arrives.
