Salt Lake City Weather 7 Day Explained (Simply)

You’re looking at the Wasatch Front right now and wondering if you should pack the heavy parka or just a light puffer. Honestly, Salt Lake City weather is doing that weird mid-winter dance where the sun looks beautiful but the air feels like a refrigerator.

Basically, if you’re planning the next week, you’re looking at a stretch of high-pressure dominance. That means lots of Vitamin D, very few snowflakes, and that classic valley haze that locals know all too well.

The Immediate Forecast: A Sunny Chill

Saturday, January 17, is starting off at a crisp 28°F under partly cloudy night skies. It’s quiet. The wind is barely moving at 1 mph from the north. As the sun comes up, things stay dry. You’ve got a high of 40°F today with total sunshine. It’s the kind of day where the snow on the side of the road looks like it’s melting, but the air still bites if you stand in the shade.

Sunday is actually the "warm" spot for the week. We’re talking a high of 45°F. Clear skies all day. If you’re heading to the mountains or just walking around Liberty Park, this is the day to do it. Just keep in mind that the low still drops to 27°F at night.

Salt Lake City Weather 7 Day Breakdown

The pattern for the rest of the week is remarkably consistent, almost like the atmosphere is stuck on repeat. Monday, January 19, dips slightly to a high of 37°F before we settle back into a groove of 40°F highs for Tuesday and Wednesday.

Cloud cover starts to creep in toward the end of the week. Thursday, January 22, looks pretty grey with a 10% chance of snow during the day and a mix of rain or snow at night. Don’t expect a blizzard; the humidity is sitting around 31%, so there’s just not a ton of moisture to work with. Friday keeps that 40°F high with some afternoon sun.

Why the Haze Matters

When we get these long stretches of high pressure in January, the valley acts like a bowl. Cold air gets trapped under a layer of warmer air—the infamous inversion. You'll likely notice the horizon getting a bit "milky" by Tuesday or Wednesday. It’s not fog; it’s just the valley holding onto everything.

If you want the cleanest air and the best views, head uphill. The mountains often stay above that trap.

What to Pack and Prepare

• Layers are non-negotiable: You’ll want a shell for the morning and a lighter layer for the 45°F afternoons.
• Hydrate: The humidity is dropping as low as 31% this week. Your skin will feel it before you do.
• Check the mountains: While the valley stays dry, the higher elevations are holding onto the snow from the New Year's storms, but no major fresh dumps are expected in this 7-day window.

Actionable Next Steps
Since the weather is holding steady and dry through mid-week, use Sunday's 45°F peak for outdoor errands or travel. By Thursday, keep an eye on the evening commute as that slight 10% chance of rain/snow could make bridges a little slick. If you’re a photographer, Saturday and Sunday offer the best "blue hour" opportunities before the valley haze thickens up by Monday afternoon.
