Right now, if you’re standing outside in Sierra Vista, you’re likely feeling that crisp, high-desert air that makes this corner of Arizona so weirdly addictive. As of 11:05 AM on this Wednesday, January 14, 2026, the current temperature Sierra Vista is sitting at a cool 57°F.
Honestly, it's a perfect morning.
The sky is completely sunny. No clouds. Just that deep, southwestern blue that looks like it was painted on. We've got a light breeze coming in from the east at about 6 mph, which is barely enough to move the dry grass, but enough to remind you it’s definitely January. Humidity is hovering at 28%, so if your skin feels like parchment, well, welcome to the neighborhood.
What the rest of the day looks like
Most people think "Arizona" and immediately picture the melting asphalt of Phoenix. Sierra Vista is different. We’re sitting up here at about 4,600 feet, nestled right against the Huachuca Mountains. That elevation is everything. It’s why, while folks in the valley are already sweating through their shirts, we’re looking at a very manageable high of 64°F for today.
Here’s the breakdown for the next few hours:
The sun is doing most of the heavy lifting. We’ve got a UV index of 2 right now, which will probably peak at 3 later this afternoon. It’s not "burn in ten minutes" territory, but the sun is stronger at this altitude. You’ll feel it on your neck if you’re out hiking Ramsey Canyon.
By the time the sun dips behind the mountains tonight, things change fast. The forecast is calling for a low of 39°F.

That’s a 25-degree drop.
In the desert, the air doesn’t hold onto heat. Once that sun is gone, the temperature falls off a cliff. If you’re heading out to dinner at one of the spots on Fry Boulevard, do yourself a favor and bring the heavy hoodie. You’re gonna need it by 7:00 PM.
The "Sky Island" effect on our local weather
Living here means understanding that our weather is dictated by the mountains. The Huachucas aren't just pretty to look at; they act like a massive thermostat. Because we’re in a "Sky Island" region—isolated mountain ranges rising out of the desert floor—we get weather patterns that would confuse a meteorologist in Tucson.
- Wind: Right now, it's an easy 6 mph from the east. Later today, expect it to shift a bit, coming from the southeast at maybe 11 mph. It’s rarely "still" here.
- Rain: Chance of rain today? 0%. Same for tonight. It’s dry. We usually don't see the real moisture until the summer monsoons or the occasional winter "Pineapple Express" system.
- Visibility: With the current conditions, you can basically see forever. The peaks of the Chiricahuas to the east are likely crystal clear today.
Planning your Wednesday in the Vista
If you're trying to figure out what to do with this 57°F weather, you’ve got options. Honestly, this is prime "active" weather. It’s too cold to sit still in the shade, but it's perfect for moving.
- Ramsey Canyon Preserve: It’s usually a few degrees cooler up in the canyon because of the shade and the creek. If it's 57°F in town, it’s probably 52°F up there. Perfect for birding without the crowds.
- Brown Canyon Trail: A bit more exposed to the sun, so that 64°F high this afternoon will feel more like 70°F while you’re climbing.
- The Loop: If you’re just walking the dog along the city’s multi-use paths, stay on the sunny side of the street. The difference between sun and shade right now is huge.
Practical takeaways for the week
The air is dry, the sun is bright, and the wind is manageable. Keep an eye on the dew point—it’s low. Drink more water than you think you need. Even though it’s "cool," the high-altitude sun and low humidity will dehydrate you before you even realize you’re thirsty.

Basically, enjoy the 64°F peak today. It’s the kind of winter day that makes people move here from the Midwest. Just don't forget that the clear skies tonight mean a frosty start tomorrow morning.
Pack your day with outdoor activities while the sun is up. Once it hits 5:00 PM, the "moderately chilly" description you see on weather apps becomes very real, very fast. Keep a jacket in the trunk of your car, keep your water bottle full, and enjoy the sun while it lasts.
