You’re probably thinking of Arizona as this monolithic block of sun-baked sand where it’s always eighty degrees. Honestly, that’s the first mistake. If you’re planning a trip, you’ve gotta realize that "Arizona weather" doesn't really exist as a single thing.
The temperature in az in february is basically a tale of two states. Down in the valley, you're looking at prime poolside lounging. Up in the high country? You might be digging your car out of a snowbank. It's a wild contrast that catches travelers off guard every single year.
The Phoenix Heat Myth
If you’re heading to the Phoenix metro area, including Scottsdale or Mesa, the numbers look pretty inviting on paper. Historically, the average high sits right around 71°F. But let's look at what actually happens. In February 2025, Phoenix literally smashed records three days in a row, with the mercury hitting a staggering 86°F by the 4th of the month.
That's not "winter." That's a full-on summer preview.
But then the sun goes down. Because the desert lacks humidity to hold onto that heat, the temperature in az in february can plummet 25 to 30 degrees the second the sky turns purple. You’ll see tourists shivering in shorts at 7:00 PM because they didn't believe the forecast. Average lows in Phoenix hover around 49°F, but it feels sharper when you’ve been basking in the sun all day.
Northern Arizona is a Different Planet
While Phoenix is flirting with the 80s, Flagstaff is a frozen wonderland. People forget that Flagstaff sits at 7,000 feet. The average high there in February is only about 45°F, and the lows? They average a brutal 20°F.
Flagstaff usually gets about 7 inches of snow during February. If you’re driving up I-17 from the desert to see the Grand Canyon, you are climbing thousands of feet in elevation. You will literally watch the thermometer on your dashboard drop a degree every few miles.

What to Expect at the Grand Canyon
The South Rim is no joke in the winter. You're looking at:
- Highs: Around 45°F
- Lows: Digging down into the 18°F range
- Surprises: Ice on the trails. If you plan on hiking below the rim, you’ll likely need microspikes.
The air is crisp, thin, and can be incredibly windy. But the trade-off is the crowds—or lack thereof. Seeing the red rocks dusted in white frosting is something most people never get to witness.
Sedona: The Middle Ground
Sedona is the weird, beautiful middle child of Arizona weather. It’s higher than Phoenix but lower than Flagstaff. February in Sedona usually sees highs in the low 60s (around 61°F) and lows near freezing (33°F).
It’s arguably the best time to hike Devil’s Bridge because you won't melt into the trail. Just keep an eye out for "flurries." Sedona gets about 2.17 inches of precipitation in February, and sometimes that comes down as a light dusting of snow that disappears by noon. It's spectacular for photography.
The Reality of Rainfall
Arizona isn't as dry as you think in February. It's actually one of the wetter months for the desert. Phoenix averages about 1.1 inches of rain. That doesn't sound like much until you realize the desert floor doesn't absorb water well.
A single storm can cause flash flooding in arroyos and canyons. According to the National Weather Service, the record rainfall for a single February day in Phoenix was 1.04 inches (set back in 2020). If you see clouds stacking up over the mountains, it’s time to stay out of the washes.
Survival Tips for the Temperature Shift
You absolutely must dress in layers. There is no way around it. A morning tee-shirt will leave you freezing by dinner.
- The Base Layer: Moisture-wicking if you’re hiking. The sun is still strong (UV index of 4 is common), so you'll sweat even if it's cool.
- The Mid-Weight: A fleece or light down "puffy" jacket is the unofficial uniform of Arizona.
- The Shell: A light windbreaker helps, especially in Sedona where the wind averages 12.7 mph.
And don't forget the sunscreen. Even if the temperature in az in february feels mild, the elevation and clear skies mean you're getting hit with way more radiation than you would in the Midwest or the East Coast.
Actionable Next Steps
- Check the specific city: Don't just look at "Arizona." Check the forecast for your exact destination.
- Pack for two seasons: Bring a swimsuit for the hotel hot tub and a heavy coat for the Grand Canyon.
- Watch the roads: If you're heading north, check the ADOT (Arizona Department of Transportation) alerts. High-country storms can shut down the interstates in minutes.
- Book early: February is "Snowbird Season." Hotels in the south fill up fast with people escaping the cold.
