If you’ve lived in the Sacramento Valley long enough, you know the "Red Bluff surprise." It’s that weird phenomenon where you expect a frozen tundra in January but end up wearing a light hoodie while the sun beats down on the walnut orchards. Honestly, the weather in red bluff ca 10 day outlook is looking exactly like that—a mix of "is it winter?" and "wait, is that a storm coming?"
Right now, as of January 17, 2026, we’re sitting at a crisp 44°F under clear night skies. But don't let the midnight chill fool you.
The 10-Day Outlook: What’s Actually Happening
Basically, we are entering a stretch of weather that feels more like early spring than the dead of winter. Today, Saturday, we’re hitting a high of 62°F. Tomorrow? Even warmer at 65°F. If you’re planning on hitting the Sacramento River or just grabbing a coffee downtown, Monday is actually the peak of this little warm spell with a high of 66°F.
Here is the thing about Red Bluff: the north wind usually dictates your life. Right now, it's a gentle 6 mph, but that’s what keeps the valley floor from getting too swampy.
As we look deeper into next week, things stay pretty consistent. Tuesday and Wednesday (January 20-21) will see highs hovering between 60°F and 62°F. It’s not until we get toward next weekend, around January 24, that the clouds really move in and drop us back down to the mid-50s.

Why Red Bluff Weather is Different Than Redding
A lot of people think since we're just down I-5 from Redding, the weather is identical. Kinda, but not really. We’re at an elevation of only 315 feet. We often miss the heavy snow that hits the foothills near Shasta Lake, but we get the wind.
When the weather in red bluff ca 10 day forecast shows a north wind, it usually means clear skies and "dry cold." When that wind flips to the south—which we’ll see by Saturday, January 24—that's when the moisture gets trapped against the mountains.
Breaking Down the Daily Vibes
- The Warm Stretch (Jan 17 - Jan 19): Highs in the mid-60s. Lows around 40°F. You’ll need a jacket at 7:00 AM, but you’ll be throwing it in the backseat by noon.
- The Transition (Jan 20 - Jan 22): Mostly sunny to partly cloudy. Highs staying around 61°F. It’s perfect "yard work" weather before the ground gets too wet again.
- The Gray Shift (Jan 23 - Jan 26): This is where the 10-day forecast gets a bit moody. Temperatures dip to 55°F by the 24th, and humidity jumps up to 80%.
Precipitation: Will it actually rain?
The chance of rain is hovering at a measly 10% for most of the week. Honestly, don't cancel your outdoor plans yet. Even when the forecast says "cloudy" toward the end of the 10-day window, the chance of a significant soaking remains low. We're looking at a 25% chance of showers by Monday night, January 26, but that's a long way off in "valley time."
The Expert Reality Check
Historical data from the Western Regional Climate Center shows that a "normal" January high in Red Bluff is about 54.6°F. We are currently trending nearly 10 degrees above that. This isn't just a random fluke; the Pacific Southwest long-range forecast for 2026 predicted a warmer-than-average start to the year.

While it feels great to have a 66°F Monday, keep in mind that the "Coldest Month" title usually belongs to December or January here. The fact that our lows are staying at 39°F or 40°F means we aren't seeing the hard freezes that kill off the citrus trees just yet.
What to Wear This Week
You’ve gotta dress in layers. It’s the only way to survive a 25-degree temperature swing.
- Morning (40°F): Heavy sweater or a medium puffer jacket.
- Afternoon (65°F): Long-sleeve tee or a light flannel.
- Evening (50°F): Back to the hoodie.
The humidity is sitting around 60%, so it doesn't feel like that "bone-chilling" wet cold we sometimes get. It’s more of a crisp, dry air.

Clean out your gutters now. Even though the rain chances are low this week, the shift toward cloudy weather on the 24th suggests the pattern is changing.
Check your tire pressure. These 20-to-30-degree daily temperature swings are notorious for triggering that "low tire pressure" light on your dashboard.
Lastly, if you’re heading north toward the mountains, remember that while it’s 62°F and sunny in Red Bluff, the Sierra and Lassen areas are still under winter conditions. Always check the pass reports before you hit the road.
