Honestly, if you’re looking at a scottsdale 14 day weather forecast and expecting a predictable desert oven, you’re in for a bit of a surprise. It's January 18, 2026, and the Sonoran Desert is currently doing that weird thing where it pretends to be a temperate paradise while secretly plotting a chilly evening.
Today is actually pretty gorgeous. Right now, it's 70°F with a light 1 mph breeze coming out of the east. Humidity is sitting at a crisp 17%. It’s that kind of weather where you feel like a genius for traveling here, but don’t let the afternoon sun fool you into leaving your jacket at the hotel.
The Reality of the Scottsdale 14 Day Weather Forecast
Most people think "Arizona" and immediately pack nothing but shorts and flip-flops. Huge mistake. While our high today is hitting a comfortable 75°F under partly sunny skies, the low is going to plummet to 45°F tonight. That’s a 30-degree swing. Basically, you’ll be sunbathing at 2:00 PM and shivering by the fire pit at 8:00 PM.
The next few days stay remarkably consistent, which is great for golfers heading to the Scottsdale courses.
- Monday, Jan 19: Expect a high of 73°F and a low of 44°F. It'll stay partly sunny.
- Tuesday, Jan 20: The sun really comes out. High of 75°F, low of 46°F. Perfect outdoor weather.
- Wednesday, Jan 21: We see a bit more cloud cover. Mostly cloudy with a high of 73°F. There’s a tiny 10% chance of rain, but honestly, it’s probably just enough to make your car look dusty.
Why the Mid-Forecast Shift Matters
If you're planning your trip around the second half of this scottsdale 14 day weather forecast, keep an eye on Sunday, January 25. The pattern shifts. We’re looking at a 35% chance of showers and a high that drops to 69°F. For a local, that’s "parka weather." For a visitor from Chicago, it’s still probably T-shirt weather, but the "chance of showers" in the desert usually means brief, intense bursts rather than a day-long drizzle.

By the time we hit the end of January, things warm right back up. Tuesday, January 27, is looking like 76°F, and Wednesday, January 28, could hit 78°F.
Layers Are Your Best Friend
You’ve probably heard it a million times, but it’s the absolute truth. The UV index is currently around 2 or 3, which sounds low, but the desert sun is deceptive. You’ll feel the heat on your skin even when the air is 70°F.

The wind is generally calm, hovering between 1 and 6 mph from various directions (mostly southeast or east lately). It’s not enough to ruin a tee time, but it’s enough to carry the scent of creosote if those clouds on the 25th actually decide to drop some water.
Honestly, the "Goldilocks" zone for this forecast is right now through the 24th. You get those mid-70s highs and crisp, clear nights that make the desert stars look like they’re right on top of you.
Actionable Travel Insights
- Sunscreen is non-negotiable: Even with "partly sunny" conditions and a low UV index, the elevation and thin air mean you'll burn faster than you think.
- Dinner reservations: If you’re eating outdoors, check the forecast low for that night. If it’s under 50°F (which it is for the next week), make sure the restaurant has patio heaters or request a table inside.
- The "Rain" Factor: A 10% or 20% chance of rain in Scottsdale often results in nothing more than a few "fat drops" that dry before they hit the pavement. Don't cancel your hike unless that percentage climbs above 40%.
- Morning Starts: If you’re hiking Camelback or Gateway early, it will be in the mid-40s. Wear a windbreaker you can tie around your waist, because by the time you’re halfway up, it’ll feel like 80°F.
The desert in January is a vibe, but it's a fickle one. Trust the numbers, but pack for the swings.
