Honestly, if you’ve spent more than five minutes in Spanish Fork, you know the weather here isn't just about what the app says. It’s about the mountains. You can look at a generic forecast for Utah County, but Spanish Fork plays by its own rules, largely thanks to that massive gap in the Wasatch Range to the east.
Basically, the Spanish Fork Canyon acts like a giant wind tunnel.
Today, Sunday, January 18, 2026, we’re looking at a high of 42°F. It’s one of those crisp, bright January days where the sun feels great through a window, but the air still has that bite. Right now, it’s 42°F and partly sunny, with a tiny 1 mph breeze coming from the west. But don't let that stillness fool you. Tonight, the temperature is going to crater down to 15°F.
The Spanish Fork Canyon Wind Factor
What most people get wrong about the weather forecast Spanish Fork Utah is ignoring the "exit jet." That’s a fancy term meteorologists like Brian Blaylock use for the wind that pours out of the canyon.
On many nights, while Provo or Orem might be sitting in a stagnant inversion, Spanish Fork stays clear. Why? Because the canyon breezes blow from the southeast, physically pushing the gunk out of the air. It’s why we have those iconic wind turbines at the mouth of the canyon. They aren’t just for show; they’re capturing terrain-induced flows that can gust up to 28 mph even when the rest of the valley is calm.

If you're planning a morning run or heading out early for work, that southeast wind is your best friend for air quality but your worst enemy for wind chill.
What the Next Few Days Look Like
We are in a very stable, dry pattern right now. If you're tired of shoveling, you're in luck.
- Monday, Jan 19: Expect a carbon copy of today. High of 42°F, low of 15°F. Pure sunshine.
- Tuesday, Jan 20: A tiny bit warmer at 43°F, but the overnight low drops to 14°F. Keep the faucets dripping if your pipes are prone to freezing.
- Wednesday, Jan 21: We might see some clouds roll in. High of 44°F, low of 14°F. Still only a 10% chance of a stray snowflake.
It’s kind of a "Groundhog Day" situation through the weekend. Highs stay in the low-to-mid 40s, and lows stay firmly in the teens. By Friday, January 23, we might hit 45°F, which feels like a heatwave when you've been hovering at freezing for a month.
Why January in Spanish Fork is Deceptive
In Spanish Fork, January is technically our coldest month. Historically, our average high is only about 35°F. Seeing 42°F today means we’re running a bit above average, which is nice for the heating bill but weird for the snowpack.

Local experts often point out that while April is our wettest month, January is when we usually get our most consistent "lake effect" or "clipper" snow. But looking at the current data, the precipitation chance is holding steady at nearly 0% for the next several days.
The humidity is sitting at 42% right now. That’s "chapstick and lotion" weather. If you're coming from the coast, your skin is going to feel it.
Actionable Survival Tips for This Week
1. Layer for the 30-degree swing. When you leave the house at 7:00 AM, it’s going to be near 15°F. By 2:00 PM, it’s 42°F. A heavy parka is great for the morning, but you’ll want a lighter fleece underneath for the afternoon sun.
2. Watch the Canyon Road. Even with no snow in the forecast, the shade in Spanish Fork Canyon means ice can linger long after the valley roads are dry. If you’re commuting toward Price, watch for those "black ice" patches near the power plant.

3. Check your tire pressure. These deep overnight freezes (down to 14°F on Tuesday night) cause air to contract. If your "low tire" light comes on Wednesday morning, it’s probably just the cold, not a nail.
4. Humidity management. With humidity at 42% and dropping, run a humidifier in the bedroom. It helps with the static shocks and keeps your nose from drying out.
The big takeaway? Enjoy the sun while it lasts. This kind of "sunny but freezing" stretch is typical for mid-January here, but it usually ends with a sudden, massive dump of snow once the Pacific moisture finally breaks through the high pressure. For now, keep the scraper handy for the frost, but leave the heavy shovel in the garage.
Make sure your car emergency kit has blankets and jumper cables. Even if it's sunny, a breakdown in 15-degree weather becomes a safety issue fast.
