You’ve probably heard the jokes about the Oregon coast. People say it only rains once a year—for nine months straight. Honestly, if you’re looking at the weather report for Coos Bay Oregon right now, you might see a bunch of cloud icons and assume you should just stay inside with a book.
But that’s not really how it works here.
Basically, Coos Bay is the land of "perpetual autumn." It’s a place where the air always smells like salt and pine, and where the temperature is so consistent it’s almost spooky. While most of the country is either melting in the summer or freezing in the winter, Coos Bay just kinda... stays in the 50s and 60s.
The Current Situation: January in the Bay
If you're checking the forecast today, Sunday, January 18, 2026, it’s actually looking pretty decent for a winter day. Right now, it's about 51°F and partly sunny. There’s a tiny 10% chance of rain, but honestly, that’s basically "dry" by local standards. The wind is a light 3 mph coming from the north, so it’s not even that biting.
Tomorrow, Monday, January 19, is actually supposed to be a bit of a standout. We’re looking at a high of 63°F. For January? That’s practically a heatwave. It’ll be sunny during the day, though it’ll drop back down to about 41°F at night.

Here is the quick breakdown of what the next few days look like:
- Tuesday (Jan 20): Cloudy and 55°F.
- Wednesday (Jan 21): Stays cloudy, high of 52°F.
- Thursday (Jan 22): Partly sunny, cooling off to 49°F.
- Friday (Jan 23): Another partly sunny one, holding at 49°F.
It’s a classic winter stretch. High humidity (around 80%), low UV index, and just enough sun to remind you it exists.
The Myth of the "Solid Wall of Rain"
Most visitors expect a downpour. They pack heavy yellow slickers and galoshes, expecting to stand in a monsoon. In reality, the weather report for Coos Bay Oregon usually reflects a "damp" reality rather than a "drenched" one.
The rain here often happens at night. You wake up, the pavement is wet, the trees are dripping, but the sky is just a soft, misty gray. Locals call it "the gloom," but it’s a cozy kind of gloom. According to the Bay Area Chamber of Commerce, Coos Bay gets about 64 inches of rain a year. Compare that to the national average of 38 inches, and yeah, it’s wet. But it’s a slow, steady rain that feeds the massive Sitka spruces and keeps the rhododendrons happy.
Snow? Forget about it. It’s rare. You might see a dusting once every few years, but it usually melts before you can even find your camera. If you see a snowflake in Coos Bay, the whole town basically stops to stare at it.
Why the Wind is the Real Boss
If you’re planning a trip to Shore Acres State Park—which you absolutely should—the temperature matters way less than the wind.

During the winter, wind gusts can hit 50 mph easily. When those Pacific winds hit the 80-foot sandstone cliffs, you get the legendary storm watching that Coos Bay is famous for. We’re talking 30-foot waves that look like exploding skyscrapers.
Knowing Your Seasons
- The Wet Season (October to May): This is for the soul-searchers. It’s misty, green, and empty of tourists.
- The Dry Season (June to September): This is "Glorious Season." Clear skies, highs in the high 60s or low 70s, and perfect for the Oregon Dunes.
One weird thing about the weather report for Coos Bay Oregon is the "fog zone." You can be standing at the waterfront in a chilly, damp fog, drive one mile inland, and it’s suddenly 75 degrees and sunny. The ocean basically acts as a giant air conditioner that sometimes forgets to turn off.
Actionable Tips for Navigating the Forecast
Don't let a "cloudy" forecast ruin your plans. Often, that just means a high marine layer that breaks by noon. If you’re heading out this week, here is what you actually need to do:
- Trust the "Percentage of Rain" with caution. In Coos Bay, 10% or 20% usually means you won't even need an umbrella. It’s more of a suggestion of moisture than a threat.
- Layer like a pro. A cotton hoodie is your enemy here—it just soaks up the mist. Go with a light synthetic base and a windproof shell.
- Check the tides, not just the sky. If you're going to the beach, the tide report is more important than the rain report. Sneaker waves are a real thing here; never turn your back on the ocean, especially during these January swells.
- Head to the gardens. If it’s drizzling, Shore Acres' formal gardens are actually more beautiful. The moisture makes the colors pop in a way that bright sun washes out.
The reality of the weather report for Coos Bay Oregon is that it’s rarely "perfect" but almost always "manageable." It’s a climate that demands you slow down, grab a cup of coffee, and enjoy the drama of the Pacific.
Check the hourly updates if you're planning to hike the dunes, as windows of sunshine often pop up when you least expect them. Stick to waterproof footwear, keep a spare pair of socks in the car, and you’ll find that the Oregon coast weather is actually the best part of the experience.
