Honestly, most people think Utah is just one giant, frozen tundra once January hits. They picture Park City snow drifts or Salt Lake City inversions. But if you’re looking at the saint george utah weather 10 day forecast, you’ll quickly realize this corner of the state is playing by a completely different set of rules.
It’s the "Arizona of Utah." Basically, while the rest of the state is digging out their driveways, St. George is usually basking in the kind of crisp, desert sun that makes you want to cancel your meetings and go for a hike.
The Current Situation: A Winter Oasis
Right now, as of Saturday, January 17, 2026, things are looking pretty sweet. The current temperature is sitting at 58°F. That’s light-jacket weather, folks. We’ve got a northeast wind barely whispering at 1 mph, and the humidity is a bone-dry 28%.
If you’re here today, you’re looking at a high of 59°F under sunny skies. Tonight, it’ll dip down to 35°F and get a bit cloudy, but that’s standard desert behavior. The heat leaves the minute the sun goes behind the cliffs.
Breaking Down the Saint George Utah Weather 10 Day Forecast
Let's get into the nitty-gritty of what the next week and a half looks like. If you're planning a trip to Zion or just want to hit the links at Dixie Red Hills, here is the breakdown:
- Sunday, Jan 18: Expect a high of 60°F. It’ll be partly sunny, which is basically code for "perfect hiking weather." Low of 36°F.
- Monday, Jan 19: Back to full sun. High of 57°F and a low of 34°F. The northeast wind picks up slightly to 5 mph.
- Tuesday, Jan 20: Still sunny. High of 54°F, low of 33°F. This is the coolest day of the stretch, so maybe grab the heavier fleece.
- Wednesday, Jan 21: Clouds roll in. We’re looking at 55°F for the high and 34°F for the low. There’s a tiny 10% chance of rain, but in St. George, that usually means three drops and a lot of grey sky.
- Thursday, Jan 22: Partly sunny again. High of 56°F, low of 39°F.
- Friday, Jan 23: Mostly sunny. High of 56°F, low of 38°F.
- Saturday, Jan 24: High of 55°F, low of 37°F. We might see a 15% chance of rain, so keep an eye on the clouds if you're out in the lava fields.
- Sunday, Jan 25: Partly sunny, high of 55°F, low of 36°F.
- Monday, Jan 26: Clearing up for a gorgeous high of 57°F and a low of 36°F.
Why the "Dry Cold" Actually Matters
You've probably heard people talk about "dry heat" in the summer. Well, "dry cold" is a real thing too.
Because the humidity is hovering around 35% to 40% throughout this forecast, 55°F feels significantly warmer than it would in, say, Seattle or New York. There’s no dampness to seep into your bones. When the sun hits your face in Snow Canyon, you’ll likely be stripping down to a t-shirt within twenty minutes.

What to Actually Do with This Weather
St. George in January is a goldmine for people who hate crowds.
Zion National Park is just 45 minutes away. In the summer, you’re fighting for a spot on a shuttle like it’s a Black Friday sale. In January? You can often drive your own car into the canyon. With highs in the mid-50s, trails like Angel’s Landing (if you have the permit) or Scout Lookout are actually safer because you aren’t battling 100-degree heat exhaustion.
Golfing is a year-round sport here. Courses like The Ledges or Sunbrook are wide open. With the saint george utah weather 10 day forecast showing mostly sun and low winds (we’re talking 2 to 5 mph), your ball isn't going to get bullied by the atmosphere.
Misconceptions About Desert Winters
One thing people get wrong: they forget the "Low" temperature.
Just because it’s 60°F at 2:00 PM doesn’t mean you can walk around in shorts at 8:00 PM. The temperature drop is aggressive. The forecast shows lows consistently in the mid-30s. If you’re camping at Sand Hollow or Quail Creek, you need a serious sleeping bag. The desert doesn't hold onto its warmth.
Actionable Tips for Your Visit
- Layering is the only way: Start with a base layer, add a hoodie, and top it with a windbreaker. You’ll be taking them off and putting them back on all day.
- Moisturize like your life depends on it: That 28% humidity will turn your skin into parchment paper.
- Check the UV index: Even though it’s January, the index is around 2. It’s not high, but that desert sun is direct. Sunglasses are mandatory.
- Trail conditions: Most red rock trails stay dry. However, if that 15% chance of rain on Saturday hits, stay off the sensitive cryptobiotic soil and be careful on the slickrock—it gets surprisingly slippery.
St. George is basically the ultimate winter cheat code. You get the beauty of the American Southwest without the summer "surface-of-the-sun" vibes. Pack a jacket, grab your hiking boots, and enjoy the sun while everyone else is shoveling snow.
