If you’re staring at your skis in the garage and wondering if a trip up to 6,700 feet is still worth it, I get it. Honestly, predicting the big bear 30 day forecast is kinda like trying to guess which line at the grocery store will move fastest—there's a lot of science involved, but Mother Nature usually has her own chaotic agenda. Right now, as we move through mid-January 2026, the San Bernardino mountains are caught in a weird tug-of-war between a weakening La Niña and some unseasonably warm high-pressure ridges.
The Reality of the Big Bear 30 Day Forecast Right Now
We need to talk about the "inversion." Forecasters like Bradford Swanson have been pointing out that while it feels like T-shirt weather at the base, a localized temperature inversion is actually the only thing keeping the snow from disappearing into the soil.
Basically, the cold air is trapped right on the surface of the runs. This means even if the "official" temperature says 50°F, the snow stays firm enough to ride. But let’s be real: the next 30 days are looking more like "spring skiing" than a mid-winter powder fest.
What the Numbers Actually Look Like
Looking at the data from the National Weather Service and local legends like Bensweather, the trend for the rest of January and early February 2026 is "dry and mild."
- Daytime Highs: Expect a lot of days in the high 40s and even low 50s.
- Nighttime Lows: This is the crucial part. We’re still seeing dips into the low 20s.
- The "Saving Grace": Those freezing nights allow the snowmaking teams at Snow Summit and Bear Mountain to blast the "man-made" stuff, even if the sky isn't helping out.
The long-range outlook from the Climate Prediction Center suggests a transition to "ENSO-neutral" conditions. For us, that usually means the storm track is being pushed way north toward Oregon and Washington, leaving Southern California under a big dome of "meh" weather.
Snow Conditions: Hard Pack and "Mashed Potatoes"
You've probably heard people complaining that there’s no "real" snow. It’s a common misconception that if it hasn't snowed in a week, the mountain is closed. Not true.
Bear Mountain and Snow Summit are currently sitting on a base of about 18 to 36 inches, depending on which peak you’re looking at. Most of that is high-density, machine-made snow. In the morning, it’s going to be fast and icy. By 1:00 PM? It’s going to feel like riding through mashed potatoes.
If you're planning your trip within this big bear 30 day forecast window, aim for the mid-week. Why? Because the heat from thousands of bodies on the weekend actually degrades the snow faster than the sun does. Plus, you won't spend half your life waiting for Chair 9.
Travel Logistics and Road Realities
Don't let the sunny forecast fool you into leaving your chains at home. Caltrans is notorious for keeping R-2 requirements active on Highway 18 or 38 if there's even a hint of "black ice" in the shadows near Onyx Summit.
Also, keep an eye on the SR-38 closures. There have been ongoing weekday closures from 7:00 AM to 5:00 PM between Mill Creek and Hills Ranch. If you’re coming from Redlands on a Tuesday, you might get a nasty surprise if you don't check the Caltrans QuickMap first.
Is There a "Miracle March" Coming?
Historically, Big Bear gets some of its weirdest, heaviest dumps late in the season. While the current big bear 30 day forecast shows a lot of sun icons, the models are hinting at a pattern shift toward the very end of February.
We saw this in 2023 and again in early 2025—weeks of dry weather followed by a "Pineapple Express" atmospheric river that drops three feet in 48 hours. If you’re a powder hound, you’re basically playing a waiting game right now. The smart money is on booking a flexible rental for the last week of February.
Beyond the Slopes: What to Do When it’s Too Warm
If the "slush factor" gets too high, Big Bear in 2026 has actually become a decent hiking destination even in winter. Since the snowpack is lower than average this year, many of the lower-elevation trails like Castle Rock or the Alpine Pedal Path are mostly clear.
- Check out the Village: It’s less crowded when the snow report isn't "Epic."
- Alpine Slide: If you have kids, the Magic Mountain area usually keeps their tubing runs iced down even when the natural snow is gone.
- The Lake: It’s beautiful, but don't even think about walking on it. The ice is nowhere near thick enough this year.
Making the Most of the Current Forecast
If you’re heading up, change your expectations. This isn't a "deep powder" month. It’s a "sunscreen and beer on the deck at Boathouse" month.
Sharpen your edges. The morning ice is real, and dull skis will have you sliding all over the place on Geronimo. Wear layers, because you’ll be stripping down to a hoodie by noon.

Actionable Next Steps:
- Monitor the "Inversion": Watch the dew point on local weather stations; if it stays low (under 20°F), the snow quality will survive the heat.
- Buy Tickets Early: Even in "bad" weather years, weekends at Big Bear sell out because everyone in LA has the same idea.
- Check Highway 38: Verify the weekday closure schedule before you leave the 10 freeway to avoid a 40-minute detour through Running Springs.
The big bear 30 day forecast might not be showing a blizzard, but for a day trip to escape the valley heat, the "Spring in January" vibes are actually pretty decent. Just don't forget the wax for your board—warm snow is sticky.
