You’ve seen the photos. Those glowing red rocks, the impossibly blue sky, and maybe a lone hiker looking like they’re having a spiritual awakening. It looks like a postcard that never changes. But honestly, if you’re planning a trip based on a generic "desert" mental image, you’re probably going to pack the wrong stuff.
Sedona isn't Phoenix. It’s also not Flagstaff. It sits in this weird, beautiful middle ground at 4,500 feet of elevation that makes the sedona arizona weather forecast a bit of a trickster.
Right now, if you’re looking at the immediate window for mid-January 2026, it’s classic high-desert winter. We’re talking crisp. Today, January 17, the high is hitting 61°F, which feels amazing under the sun. But don't let that fool you into thinking it's t-shirt weather all day. Tonight, it’s dropping to a biting 22°F. That’s a 39-degree swing. If you aren't prepared for that kind of volatility, the desert will humble you real quick.
The Microclimate Reality Check
Most people check the weather and see "sunny" and assume they’re good to go. But in Sedona, the temperature is basically a suggestion depending on where you're standing.
Are you deep in the shade of Oak Creek Canyon? It might be ten degrees cooler than the exposed face of Bell Rock. Are you hiking a north-facing slope? You might find patches of ice or snow lingering weeks after a storm while the south side of the same hill is bone-dry and dusty.
Why January is Secretly Great (and Cold)
If you’re here this week, you’ve got clear skies through Tuesday, January 20. The highs stay remarkably consistent around 61°F to 62°F. It’s the nights that'll get ya. Tuesday night is looking particularly frosty at 18°F.
- Sunday, Jan 18: Partly sunny, high of 61°F.
- Monday, Jan 19: Full sun, high of 62°F.
- Tuesday, Jan 20: Sunny, high of 61°F.
The air is incredibly dry right now—humidity is hovering around 30% to 45%. You won’t feel like you’re sweating, but you’re losing moisture fast. Drink more water than you think you need. Seriously.
Surviving the "Four Seasons" in One Day
Sedona doesn't really do "mild" in the way people from the coast think of it. It does "intense" in different flavors.
Spring and fall are the "Goldilocks" zones. March and October are the busiest months for a reason. In April, you're looking at highs in the mid-70s, which is perfect for hitting Devil's Bridge without melting. But because everyone knows this, the trails get packed. You’ll be sharing that "solitude" with 50 other people waiting for a photo op.
Summer is a different beast. June brings the heat, often hitting the 90s. Then the monsoons roll in around July and August.
I’ve seen people get caught in a monsoon downpour, and it’s spectacular but sketchy. One minute it’s 95°F and baking; the next, the sky turns purple, the wind howls, and you’re getting pelted by rain that drops the temp by 20 degrees in minutes. It’s the only time of year you’ll actually see the waterfalls come alive on the red rock faces. Just stay out of the washes. Flash floods are no joke here.
The Monsoon Strategy
If you're visiting during the official monsoon window (June 15 to September 30), follow the "Early Bird" rule. Hike at sunrise. Be off the exposed rock by 10:00 AM. If you see those puffy white clouds starting to tower and turn grey over the Mogollon Rim, that’s your cue to find a patio with a roof.
Packing for the Sedona Arizona Weather Forecast
Stop bringing just flip-flops. I see it every year. People try to hike Cathedral Rock in Birkenstocks because the weather app said it was 75°F. The rock is slick, the gravel is loose, and the sun is relentless.

Basically, you need a "layering system."
I usually start a morning hike in a fleece and a beanie when it’s 35°F. By the time I’ve climbed 500 feet and the sun has cleared the ridge, I’m down to a moisture-wicking t-shirt.
- Winter Essentials: A real puffer jacket, gloves for the early hours, and shoes with actual grip (Vibram soles are your friend).
- Summer Essentials: A wide-brimmed hat—not just a baseball cap, you want your ears covered—and a hydration bladder.
- The "Dark Sky" Factor: Since Sedona is a certified Dark Sky Community, it gets dark-dark. If you're planning a sunset hike, bring a headlamp. Using your phone flashlight while navigating red rock switchbacks is a recipe for a twisted ankle.
What Most People Get Wrong About Rain
Rain in Sedona isn't like rain in Seattle. It doesn't usually drizzle for three days straight. It’s usually punchy and dramatic.
If the sedona arizona weather forecast calls for a 30% chance of rain, like it does for Sunday, January 25, that usually means a passing cell. The clouds break, the sun hits the wet rocks, and the colors become so saturated they look fake. It’s actually the best time for photography. The "boring" blue sky gets replaced by moody shadows and mist.
If it does actually pour, head to the galleries in Tlaquepaque or hop on the Verde Canyon Railroad in nearby Clarkdale. The train has covered cars, and the canyon looks incredible when it's misty and moody.
Looking Ahead to Next Week
The forecast shows a shift toward the end of the month. Around Thursday, January 22, we start seeing more cloud cover. By Sunday the 25th, the chance of rain jumps to 30-35%. Temps will dip slightly into the mid-50s. It’s a good reminder that winter in the high desert is a marathon, not a sprint.
Don't let a low-temperature forecast scare you off. The "feels like" temp in the direct sun is often much warmer than the thermometer says. Just respect the shade. The moment you step out of the sun, you'll feel that 10-degree drop immediately.
Actionable Tips for Your Trip
Before you head out to the trailhead, check the National Weather Service's local office for Flagstaff/Sedona. They give much better detail on wind gusts than the generic apps.
- Download offline maps. When the clouds roll in, GPS can get wonky in the canyons, and you don't want to be guessing which trail marker is yours when the light is fading.
- Pack "Salty" Snacks. In this dry air, you're losing electrolytes. Water alone won't keep you from getting that high-altitude headache.
- Respect the "Stupid Motorist Law." If a road is flooded during a storm, do not drive through it. Arizona has a law where you might have to pay for your own rescue if you bypass a barricade.
- Check the UV Index. Even when it's 60°F in January, the sun at this altitude will burn you. Wear the sunscreen.
The weather here is part of the experience. It’s not something to just "tolerate"—it’s what shaped the landscape. The wind, the freezing nights, and the summer deluges are why the rocks look the way they do. Dress for the chaos, and you'll have a much better time.
