Honestly, if you're checking the weather forecast Queenstown New Zealand 10 days out and seeing nothing but sun icons, you’re only getting half the story.
Queenstown in January is a bit of a trickster. It's mid-summer down here in the Southern Hemisphere, and while places like Auckland are currently sweating under subtropical humidity and heavy rain warnings, our alpine pocket is playing a different game.
Today, Monday, January 19, 2026, we’re waking up to a crisp $45^{\circ}\text{F}$ ($7^{\circ}\text{C}$). By the afternoon, it’ll hit $69^{\circ}\text{F}$ ($20^{\circ}\text{C}$)—ideal for a cruise on the TSS Earnslaw, but definitely "sweater weather" the moment the sun dips behind the Remarkables.
The 10-Day Breakdown: Sun, Clouds, and the Southwest Shift
Looking at the upcoming week, we have a classic alpine transition.
Tuesday and Wednesday (January 20–21) stay mostly settled with highs creeping up to $71^{\circ}\text{F}$. It’s the kind of weather that makes Lake Wakatipu look like glass. But keep an eye on Thursday. A system is moving through that will likely bring the first real "gray" period.

Clouds will thicken on Thursday, January 22, and by Friday, the temperature takes a noticeable dive. We’re looking at a high of just $57^{\circ}\text{F}$ ($14^{\circ}\text{C}$) on Friday with light rain. If you’ve planned a bungy jump or a canyoning trip, this is where that "waterproof layer" advice from the locals becomes law, not just a suggestion.
The weekend (January 24–25) stays cool. Expect highs of $54^{\circ}\text{F}$ to $63^{\circ}\text{F}$. It’s not "winter" cold, but with the southwest wind kicking up to 8 mph, it’ll feel biting if you're standing on top of Bob's Peak.
Things bounce back quickly, though. By next Tuesday, January 27, we’re forecasting a jump back up to $75^{\circ}\text{F}$ ($24^{\circ}\text{C}$). That’s the Queenstown yo-yo for you.
Why the "UV Index 9" is the Most Important Number
Most people focus on the rain, but in New Zealand, the sun is the real boss.

Today and tomorrow, the UV index is hitting 9. That is "Extreme" territory. Because the air here is so clean and the ozone layer is thinner than what you're used to in the Northern Hemisphere, you will burn in minutes.
I’ve seen tourists come off the Shotover Jet looking like lobsters because they thought a $69^{\circ}\text{F}$ day meant "mild" sun. It doesn't. You need SPF 50+ even if it feels breezy and cool.
Packing for the Alpine "Mood Swings"
Don't trust a single-layer outfit. Ever.
Queenstown is famous for its "four seasons in one day" reputation, though January usually limits that to two or three. Since the humidity is relatively low (around 56% today), the temperature drops the second the sun is obscured.

- The Base: A t-shirt or light long-sleeve.
- The Insulation: A light down jacket or wool sweater (essential for the $41^{\circ}\text{F}$ nights).
- The Shell: A high-quality rain jacket. Friday’s 35% chance of rain might sound low, but in the mountains, that can mean a localized downpour that soaks you in seconds.
Local Insights: Beyond the Numbers
While the rest of the country deals with that subtropical low forming up north, Queenstown’s position in the lee of the Southern Alps usually acts as a shield.
NIWA (the National Institute of Water and Atmospheric Research) indicates that while soil moisture is low across the South Island, we aren't quite in a drought yet. However, Fire and Emergency NZ (FENZ) has already moved several areas into "Restricted" or "Prohibited" fire seasons. If you're camping near Moke Lake or out toward Glenorchy, be incredibly careful.
One more thing: the wind.
We’re seeing easterlies today, but it shifts southwest by Friday. Southwest winds in Queenstown usually mean the "front" has arrived. It brings that cooler, cleaner air from the Southern Ocean. It’s refreshing, sure, but it’ll kill your picnic plans if you aren't sheltered.
Your Actionable Checklist for the Next 10 Days
If you're on the ground or arriving this week, here’s the plan:
- Book water-based activities for Monday through Wednesday. The lake will be calmest and the air warmest.
- Move indoor plans to Friday. The $57^{\circ}\text{F}$ high and rain chance make it the perfect day for the boutiques in Arrowtown or a long lunch at a winery in Gibbston.
- Monitor the "MetService" app daily. Mountain weather moves faster than global models can sometimes predict.
- Hydrate. The dry alpine air and high UV can lead to altitude-style headaches if you’re not careful.
Queenstown is stunning regardless of the clouds, but knowing that a $70^{\circ}\text{F}$ Tuesday can turn into a $54^{\circ}\text{F}$ Saturday is the key to actually enjoying it. Pack the jacket, wear the sunscreen, and don't let a little Friday rain stop you from seeing the most beautiful corner of the world.
