If you just looked out your window in the Rose City, you probably saw exactly what I did: a slab of gray that looks more like a wet concrete ceiling than a sky. Standard Portland, right? Well, not exactly. If you’ve been tracking the weather portland oregon 14 day trends lately, you’ve likely noticed that January 2026 is acting a bit... off.
We just came off the warmest December on record. Honestly, it felt more like a very long, very damp October. People were actually joking on Reddit about tanning on their patios in mid-December because the average temperature hit a bizarre $46.4^\circ\text{F}$. Now, as we stare down the back half of January, the atmosphere is trying to figure out if it wants to stay in this "Spring-lite" mode or finally give us the winter wallop we usually expect this time of year.
The 14-Day Breakdown: Sun, Clouds, and the Sudden Shift
Right now, the short-term forecast is actually looking surprisingly decent, at least by Pacific Northwest standards. If you’re planning anything outside for the next week, you’re in luck. We are looking at a stretch of "mostly cloudy" to "sunny" days starting Thursday, January 15th.
Here is the vibe for the next two weeks:
- The Immediate Window (Jan 14–Jan 19): We are hitting a high-pressure ridge. Expect highs to climb into the low-to-mid 50s. Friday and Saturday look like the winners, with actual sunshine—not just "sun breaks"—and highs around $54^\circ\text{F}$. It’s the kind of weather where you see Portlanders wearing shorts and a North Face puffer simultaneously.
- The Turning Point (Jan 20–Jan 22): The party ends here. The clouds thicken back up on Tuesday, and by Wednesday the 21st, the classic light rain returns. Highs will drop back into the 40s.
- The "Wildcard" (Jan 23 and beyond): This is where it gets interesting. While the first half of the 14-day window is mild, long-range models like the GFS are sniffing out some colder air. There’s a slight chance of some "white stuff" (snow or graupel) mixing in by the 23rd as lows dip toward $33^\circ\text{F}$.
It is a classic Portland tease. One minute you're thinking about pruning the roses early, and the next, you're wondering if you need to wrap your pipes for a late-season freeze.

Why the Weather Portland Oregon 14 Day Forecast is So Volatile
You’ve probably heard meteorologists like Josh Cozart talking about the "spring-like" conditions lately. It’s mostly due to a weirdly persistent ridge of high pressure that has been blocking the usual train of Pacific storms.
But there’s a bigger player at work: La Niña.
We are currently in a weak La Niña cycle. Historically, La Niña is supposed to mean cooler and wetter for us. However, this year it’s been behaving more like a "La Nada." Instead of constant cold, we’ve had these massive atmospheric rivers—like the ones that dumped 8.5 inches of rain on us in December—followed by these eerily dry, mild stretches.
The weather portland oregon 14 day outlook reflects this "feast or famine" pattern. We aren't getting the steady, daily drizzle of the 90s. We’re getting three days of deluge, then five days of clear, cold sunshine. It makes planning a hike at Forest Park a literal gamble.

The biggest misconception? That it's always freezing.
Actually, January averages in Portland usually hover between $36^\circ\text{F}$ and $47^\circ\text{F}$. We are a temperate rainforest, not the tundra. But because it’s so humid—we’re talking 90% plus humidity right now—that $40^\circ\text{F}$ feels way deeper. It’s a "bone-chilling" dampness that no amount of wool can fully stop.
Another thing: Snow. Portlanders have collective PTSD from the 2017 and 2021 snowpocalypses. Every time the 14-day forecast shows a low of $32^\circ\text{F}$, the shelves at the Hollywood Fred Meyer get cleared of kale and milk.
But look at the data. The average snowfall for January is only about 1.3 inches. Most years, we get a "slushy inch" that melts by noon. The current 14-day outlook shows a low of $32^\circ\text{F}$ around January 19th and 20th. Will it snow? Probably not. It’ll likely just be a very frosty morning that requires some extra time with the windshield scraper.

If you’re out and about in this 14-day window, don't trust the "sunny" icons completely.
- Layers are non-negotiable. The difference between a sunny $55^\circ\text{F}$ afternoon and a $36^\circ\text{F}$ clear night is massive.
- Waterproof vs. Water-resistant. In the light rain predicted for the 21st and 22nd, water-resistant is fine. If you’re going to the coast? Get the heavy-duty GORE-TEX.
- Footwear. The ground is saturated. Even if it hasn't rained in two days, the trails are mud pits. Stick to boots.
Actionable Next Steps
Instead of just checking the app every ten minutes, here is how to actually handle the next two weeks in Portland:
- Prep the Garden (Maybe): With the dry, sunny stretch from Jan 15–19, it’s a great time to do some cleanup. But don't plant anything tender. The 14-day trend shows temperatures dropping back to near-freezing toward the end of the month.
- Schedule Outdoor Errands Now: If you need to wash the car or fix that fence slat, do it between Thursday and Monday. The rain returns mid-next week and looks like it might settle in for a while.
- Check Your Antifreeze: We’ve had a warm winter so far, which makes us lazy. With lows hitting $32^\circ\text{F}$ on Jan 19, make sure your car is actually ready for a real freeze.
- Monitor the "Arctic Surge": While the Midwest is getting hammered by polar air, keep an eye on the Columbia River Gorge. If we get "Gorge Winds" (east winds) combined with that moisture predicted for the 22nd, that’s when the 14-day forecast turns from "rainy" to "ice storm."
Stay dry, keep a flashlight handy (Portland's power lines hate ice), and enjoy those weird January sun-rays while they last.
