You’re probably checking the weather forecast whitefish montana because you’ve got a trip on the books or you’re staring at the Big Mountain summit cam, wondering if your wax choice was a mistake. Honestly, everyone thinks they know Whitefish weather—just "cold and snowy," right?
Well, kinda.
If you’re standing in downtown Whitefish today, January 15, 2026, it’s actually a bit of a teaser. The temperature is sitting right at 33°F. It’s mostly sunny with a light 2 mph breeze from the southeast. It feels like a gift. But if you're a local, you know the "Big Mountain Fog" or the "Whitefish Cloud" is never far away.
The Reality of the Weather Forecast Whitefish Montana This Week
Don’t get too comfortable with the sunshine. While today’s high is hitting 34°F, the overnight low is dropping back to 20°F. If you’re planning the rest of your week, here is the raw deal on what’s coming down the pipe:
Tomorrow, Friday, January 16, looks remarkably similar: partly sunny with a high of 31°F and a low of 18°F. It’s stable. Saturday is the outlier for the weekend—completely sunny but colder, with a high of only 27°F.
Then it gets interesting.
Starting around January 22, the "snow showers" return to the forecast. We’re looking at 20-25% chances of snow through January 24. It’s not a massive dump, but it’s enough to freshen up the tracks.
Why the Summit is a Different World
The most common mistake visitors make is looking at the town forecast and thinking it applies to the chairlift. It doesn't.
Right now, the Whitefish Mountain Resort summit (6,813 ft) is reporting a settled base of 68 inches. While the town is 33°F, the summit is often five to ten degrees colder, and the wind—currently a mild 10 mph with 15 mph gusts up high—can change the "real feel" in seconds. Helena, the resort's snow reporter, noted this morning that things are "firm and fast" due to an overnight freeze-thaw cycle.
Translation: Bring your sharp edges. The snow will soften as the day hits its peak, but those morning groomers are basically high-speed lanes.

Humidity and the "Real" Cold
Whitefish is surprisingly humid for a mountain town. Today it’s at 88%. By tonight, it’ll hit 92%. In the summer, humidity is your friend, but in a Montana winter, that moisture in the air makes the 20°F low feel like it’s biting through your layers.
It’s a "wet cold."
Basically, you’ve gotta layer better than you think.

January Trends: What to Expect Long-Term
Usually, January is the cloudiest month of the year here. We typically only get about 2 hours of actual sunshine a day. The fact that we have "mostly sunny" conditions right now is actually a bit of a statistical anomaly.
Historically, the average high for mid-January is around 29°F. We’re currently tracking slightly above that, which fits the 2026 trend of a "warmer than normal" winter. The Farmers' Almanac and local climate data both pointed toward this—fewer sub-zero stretches and more days hovering near the freezing mark.
- The Inversion: Sometimes it’s 15°F in town and 25°F at the summit. If it’s foggy in town, check the webcams. You might find a "bluebird" day above the clouds.
- The SNOW Bus: If the roads look dicey (and they often do with 90% humidity turning to ice), just take the bus. It's free and saves you the "white-knuckle" drive up the mountain.
- Visibility: On the mountain, "good visibility" can turn to "milk bowl" in ten minutes. Today’s visibility is "fabulous," but that’s not a guarantee for your Saturday session.
Actionable Steps for Your Trip
If you’re heading out, don’t just pack for the 33°F high. Pack for the 16°F lows coming next week.

- Check the 6:45 AM Snow Report: Don't wait until you're at the base. The resort updates the "firmness" of the snow early. If they say it's "slick," wear a helmet.
- Watch the UV Index: Even though it’s 1, the reflection off the snow will burn your face on these sunny days.
- Monitor the Wind: A shift to the Northeast (expected Saturday) usually brings that colder, drier air.
The weather forecast whitefish montana is telling us one thing clearly: the "spring-like" afternoon fun is here for a few days, but the snow showers are lurking just a week away. Plan your heavy skiing for the afternoons when the crust softens, and keep an eye on Thursday the 22nd for the return of the flakes.
