If you've ever spent a winter in the Umpqua Valley, you know the vibe. You wake up, look out the window, and basically see a wall of white. It's not snow—though we get that rare dusting once in a blue moon—it's the infamous valley fog. Honestly, the roseburg oregon weather forecast is more about navigating microclimates than just checking a temperature on your phone.
Right now, as we sit in mid-January 2026, the current conditions are exactly what locals expect: chilly, quiet, and exceptionally damp. It’s 35°F outside as of early this morning, January 17th. The air is heavy with 93% humidity, and while the sky is technically "clear" above the fog layer, you wouldn’t know it from the ground. There’s no wind to speak of—0 mph—so that cold air is just sitting in the basin like a stubborn guest who won't leave the party.
The Reality of the Roseburg Oregon Weather Forecast
People from out of state often think Oregon is just one big rainy forest. But Roseburg is different. We’re in this weird geographical pocket. Nestled between the Cascades and the Coast Range, the "Land of Umpqua" creates its own rules.
Today, Saturday, January 17, 2026, we’re looking at a high of 49°F. That’s actually a bit of a treat compared to yesterday's 39°F. It’ll be sunny during the day—once that fog burns off around noon—and then it'll dip back down to 34°F tonight. If you're planning to be out, just know the northwest wind will be light, maybe 2 mph, so it won’t bite too hard, but you’ll definitely want that heavy coat.

What’s Coming This Week?
Honestly, the next few days are looking pretty consistent. We’re stuck in a loop of highs in the high 40s and lows right around freezing (34°F).
- Sunday, Jan 18: Partly sunny with a high of 49°F.
- Monday, Jan 19: Full sun, high of 49°F.
- Tuesday, Jan 20: A slight warm-up to 52°F.
It’s that classic January stretch where the thermometer barely moves. You’ve basically got a 10% to 20% chance of seeing any "precipitation," but here's the kicker: the forecast is calling for "snow" as the type, even if the chance is low. Don't go buying a sled just yet, though. In Roseburg, a "chance of snow" usually means a few flakes that melt before they even hit your windshield.
Why the "Umpqua Effect" Messes With Your Apps
If you’ve ever looked at your weather app and seen "Sunny" while you’re shivering in a grey mist, you’ve experienced the inversion. The mountains trap the cold, moist air in the valley while the peaks are basking in 50-degree sunshine. It’s why the Roseburg Municipal Airport might report one thing, but if you drive ten minutes east toward Glide, it feels like a different planet.

National experts like those at the National Weather Service or WeatherTrends360 note that the West is trending warmer this year, and Roseburg is no exception. We’re seeing temperatures about 6°F warmer than this time last year. It’s a bit of a "warm" winter, if you can call 35 degrees warm.
The Rain vs. Snow Debate
Roseburg gets about 33 inches of rain a year. Most of that happens right now. Between November and January, it’s basically a sponge out here. However, 2026 has been a bit drier than average so far. We’re seeing more "mostly cloudy" days than "downpour" days.
If you look toward the end of the month, specifically around January 23rd and 24th, things might get interesting. The forecast shows a mix of rain and snow with a 35% chance of precipitation and winds picking up to 10 mph. That’s the "big" weather event for the month. But again, "rain and snow" in Roseburg usually just means "slushy mess for an hour."

Survival Tips for the Umpqua Winter
If you’re new to the area or just visiting, don’t trust the "High" temperature. A 50-degree day in Roseburg feels much colder because of the humidity. That 85% to 90% humidity carries the cold straight to your bones.
- Layer like a pro. You need a base layer for the morning fog and something breathable for the afternoon "heat" of 49 degrees.
- Watch for black ice. Since our lows are hovering right at 34°F, those damp roads turn into skating rinks by 6:00 AM.
- Get a light box. Seriously. The "mostly cloudy" streak can get to you.
The roseburg oregon weather forecast isn't just about numbers; it's about timing. If you want to hike the North Umpqua Trail, aim for that 1:00 PM to 3:00 PM window when the sun actually breaks through.
Moving into late January, expect the lows to stay steady at 34°F-37°F while the highs might climb toward the mid-50s by the 26th. It’s a slow crawl toward spring, but at least we aren't shoveling three feet of snow like the folks in the Cascades.
Stay dry, keep your headlights on in the fog, and remember: if you don't like the weather in Roseburg, just wait an hour (or drive five miles).
Actionable Next Steps:
Check your tire pressure today. Cold snaps like this morning's 35°F drop cause PSI to plummet, and with the damp roads expected this coming Saturday, you'll want that traction. If you're heading toward Diamond Lake or the higher elevations, carry chains—the valley might be 49°F and sunny, but the pass is a different story.
