Honestly, if you're looking at a st george utah weather forecast 14 day and expecting a predictable desert heatwave in the middle of January, you've got it all wrong. It's the "Dixie" of Utah, sure. But "warm" is a relative term when you're standing on red sandstone at 7:00 AM.
Right now, as of January 16, 2026, the local vibe is crisp. We’re talking clear nights and sun-drenched afternoons that make you want to quit your job and go hike Snow Canyon. But don't let that bright sun fool you into leaving your jacket at the hotel.
The Current Situation: Chill and Grill
Today in St. George, we’re looking at a high of 58°F. That’s basically t-shirt weather for the locals, but the low tonight is dropping to 34°F. That's a 24-degree swing. You've gotta dress like an onion—layers are your only hope.
The wind is barely a whisper, coming from the southwest at 3 mph. It’s the kind of day where the air feels thin and clean, but the moment the sun dips behind those black lava ridges, you’ll feel the desert's true winter teeth.
Your 14-Day Outlook (Sorta)
Looking ahead at the next couple of weeks, the pattern is surprisingly steady, which is a blessing if you're planning a golf trip or a Zion run.

- Saturday, Jan 17: Expect 57°F and sunny. Lows stay around 33°F.
- Sunday, Jan 18: A little more "exciting." We might see some clouds (partly sunny) with a high of 58°F. There’s a tiny 10% chance of snow during the day, which sounds wild for St. George, but it usually just means a few flakes that vanish before they hit the pavement.
- Monday, Jan 19: Back to perfection. High of 60°F, low of 34°F.
Basically, the rest of the week through the 25th is holding in that 58°F to 61°F range. It’s remarkably consistent. If you're coming from Salt Lake City or anywhere with a "real" winter, this feels like an early spring.
Why the Forecast Often Lies to You
Most people check a st george utah weather forecast 14 day and see "Sunny" and "60 degrees" and think they’re golden. What the app doesn't tell you is the "shadow effect."
Because St. George is surrounded by massive cliffs, you can be in the direct sun feeling like it’s 70°F, then walk ten feet into the shadow of a canyon wall and feel like it’s 40°F instantly. The dry air doesn't hold heat. Once that sun is blocked, the temperature falls off a cliff faster than a mountain biker on a bad line at Gooseberry Mesa.
Snow in the Desert?
Yeah, it happens. Rarely. The forecast for the 18th and 20th mentions a slight chance of snow. Usually, St. George only averages about 1.3 to 3.2 inches of the white stuff for the entire year. When it does snow, the red rocks look like they’ve been dusted with powdered sugar. It’s gorgeous. It also causes absolute chaos on the I-15 because nobody here owns snow tires.
If you see snow in the forecast, don't panic. It won't stick on the roads for long. The ground is usually too warm. But if you’re heading up to Zion National Park, just 45 minutes away, remember that they are higher up. What’s a light drizzle in St. George is a full-on blizzard at the Zion Mt. Carmel Tunnel.
Living the "Snowbird" Life
There’s a reason the population here explodes in the winter. While the rest of the state is dealing with "inversions"—that nasty, trapped smog in the valleys—St. George usually has blue skies.
What to Pack for the Next 14 Days
Forget the heavy parka. You’ll look like a tourist. Instead, bring:
- A solid windbreaker or light puffer. Great for the mornings.
- Sunglasses. The glare off the red rock is no joke, even in January.
- Good hiking boots. If there’s even a hint of rain or snow (like the 5-10% chances we're seeing this week), the sandstone gets slick.
- Shorts. Honestly, for the afternoons when it hits 61°F, you might actually want them if you're active.
Real Talk on Rain
January isn't exactly "wet," but we do get about 1.12 inches of precipitation on average. This week, the chances are low—mostly 0% to 10%. But desert rain is different. It doesn't soak in; it runs off. If a surprise storm hits (check the forecast for the 21st and 25th where we see a 5% bump), stay out of the washes. Flash floods are real, and they don't care about your 14-day itinerary.
Actionable Tips for Your Trip
If you're looking at the st george utah weather forecast 14 day to plan a getaway, here is how to actually play it:
- Target the mid-day window. Plan your most "exposed" activities (like biking Bearclaw Poppy or hiking the Vortex) between 10:00 AM and 3:00 PM.
- Book tee times late. Don't be the guy at the 7:00 AM frost delay. Wait until 11:00 AM when the sun has actually done its job.
- Watch the humidity. It's sitting around 40-45% this week. That's "comfortable" but still dry. You will get dehydrated without realizing it because your sweat evaporates instantly.
- Check the UV Index. It’s hovering around 3. It’s low, but at this elevation, you can still get a "winter burn" if you’re out for four hours on a bike.
The bottom line? The next two weeks in St. George are looking like the classic "Desert Winter" dream. It’s cold enough to justify a hot cocoa at a local coffee shop in the morning, but warm enough to be outside all afternoon without losing a toe to frostbite.

Keep an eye on that Sunday the 18th for the weird snow/rain mix, but otherwise, the high pressure is your friend. Grab your gear, check the NWS Salt Lake City office for any sudden "Red Flag" or "Wind" warnings, and enjoy the red rocks while the crowds are still thin.
Next Steps:
- Check the specific hourly wind gusts if you plan on cycling, as southwest winds can kick up unexpectedly in the afternoons.
- Verify trail conditions at Snow Canyon State Park if that 10% precipitation chance on Sunday manifests into actual moisture.
