Portland in December

You booked Portland for December, didn’t you. And now you are up at midnight reading weather pages, wondering whether you made a small expensive mistake. Sit down. I have good news and one piece of bad news, and you get the bad one first because that is how you know the good one is real.

The bad news is that December is the wettest, darkest month of the Portland year. Not one of them. The one.

The good news is that almost none of that ruins a trip, and some of it quietly makes the trip better. Cheap rooms. Restaurants that will actually seat you. And a sunset schedule that does something genuinely strange in the second week.

The Numbers, Before You Talk Yourself Out of It

Using the NOAA 1991 to 2020 normals for Portland International Airport, December averages a high of 46.9 degrees and a low of 36.2. Rain totals 5.77 inches across 19.2 days. Both of those are the highest of any month here, which is the part people quote at you.

The number that actually describes the month is sunshine. December gets 63.7 hours of it. That is 23 percent of what is possible, and it is the lowest of any month on the Portland calendar by a comfortable margin. January is brighter. November is brighter. December is the floor.

Now the part that saves you. The temperature almost never turns hostile. Portland averages 32 nights a year at or below freezing but only 2.1 days when the high fails to climb above it. December snow averages 1.2 inches over 0.8 days, a statistician’s way of saying most Decembers get a dusting and some get nothing.

So you are not packing for cold. You are packing for wet and dim at 45 degrees, which is a much easier problem. Waterproof shoes and a shell you can walk in for four hours. That is the entire list.

The Earliest Sunset Is Not the Solstice

This is my favorite piece of December trivia and it is genuinely useful. Everybody assumes the darkest evening of the year lands on the winter solstice, December 21. It does not. In Portland the sun sets at about 4:28 pm around December 7 through December 10, and that is the earliest it goes down all year.

By the solstice itself the sun is already setting a few minutes later, at about 4:31. By December 31 it has crawled back to about 4:38. Sunrise keeps sliding later into early January, which is why the whole month still feels like a losing battle, but the evenings start growing back before Christmas.

What you do with that. The solstice gives Portland under nine hours of daylight, sunrise about 7:46 am, sunset about 4:31 pm. That is your entire outdoor budget. Anything with a view, a trail or a garden in it happens between 9 am and 3:30 pm, and everything after is indoors whether you planned it or not.

December Is Two Different Trips and You Have to Pick One

People talk about December as one month. It is two, and they barely resemble each other.

December 1 through roughly the 20th is the quietest, cheapest, most local stretch of the Portland year. Hotel rooms downtown sit empty. Restaurants that make you fight for a July reservation will take a walk-in party of two on a Tuesday. This is when I send friends who want to eat well and be left alone.

Then the 21st hits and the city flips. Everybody with family here comes home, the holiday events stack into the same ten days, and the week between Christmas and New Year’s is the busiest thing December does. Not summer busy. But the gap between the two halves of this month is bigger than the gap between April and May.

If you are coming for the lights and the ships and the tree, you want the second half and you should book early. If you are coming for the city, come in the first three weeks and thank me later.

What Actually Closes, and On Which Day

Three December days behave differently and nobody flags them until you are standing outside a locked gate.

• Christmas Day. The Portland Japanese Garden is closed. It is also closed on Thanksgiving, on New Year’s Day and every Tuesday, so a December 22 or 29 visit is out too. Most museums follow suit even when their websites bury it.
• Transit on the holidays. TriMet runs a Sunday schedule on Thanksgiving, Christmas Day and New Year’s Day. Bus lines that do not normally run on Sundays do not run at all, and WES commuter rail does not operate on any of the three. Check your line before you rely on it.
• Mondays, all month. The Portland Art Museum is closed every Monday. Admission there is free from 10 am to 7 pm on the first Thursday of the month, which in December is a genuinely good use of a wet afternoon.

Lan Su Chinese Garden in Old Town lists no holiday closures and keeps the same hours year round, 10 am to 5:30 pm with last entry at 5. Adults $18, seniors 62 and up and students with ID $17, youth 6 to 18 $15, kids 5 and under free. In the rain it is the best twenty dollars in this city, because that garden was built around water hitting stone and leaves. It was designed for exactly the weather you are complaining about.

One caution. Holiday hours move, so confirm on the venue’s own site the week you travel.

Checked September 28, 2026: the Japanese Garden is open 10 a.m. to 5:30 p.m. and closed Tuesdays, Nov 26, Dec 25 and Jan 1 (Portland Japanese Garden); TriMet runs a Sunday schedule with no WES on Thanksgiving, Christmas Day and New Year’s Day, and all service is free after 8 p.m. on New Year’s Eve, with MAX running until about 3 a.m. (TriMet holiday service); the Art Museum is closed Mondays and free 10 a.m. to 7 p.m. on first Thursdays (Portland Art Museum); Lan Su is open daily 10 a.m. to 5:30 p.m., adults $18 (Lan Su Chinese Garden).

How to Build a Day Around Rain Instead of Around Weather Apps

Visitors keep trying to schedule around the rain. In December that is not a strategy, it is a hobby. With 19.2 rain days in a 31 day month, the forecast shows you a wall of little cloud icons and tells you nothing you can use.

What locals do is build the day around two indoor anchors with a movable outdoor hour wedged between them. Morning anchor. The outside thing goes in the middle, roughly 11 to 2, when the light is best and the temperature peaks. Evening anchor. If the middle hour gets rained out, you lost an hour, not a day.

My standing December anchors, since you will ask. Powell’s City of Books on West Burnside in the morning, because it is enormous, warm, and nobody rushes you out of it. A long coffee in the afternoon somewhere with actual seating rather than a counter and four stools. Then dinner. That is the whole shape and it works in a downpour.

Skip the umbrella for city walking. December rain here is a fine steady drizzle that comes at you sideways off the river, and an umbrella turns you into a sail with wet shoulders. Save it for the gardens, where the rain falls straight down through the trees. For a longer list of wet-day options, my rainy day guide to Portland is built for exactly this.

The Holiday Stuff Has Its Own Post, and Here Is the Short Version

I am not going to relitigate the holiday calendar here. It is already written up in my guide to celebrating Christmas in Portland, which covers the tree lighting, Peacock Lane, ZooLights, the Christmas Ship Parade, the Grotto lights, the Nutcracker and the rest, with logistics for each.

What matters for planning is that those events are concentrated, not spread. Several run only on specific nights, and the good ones sell timed tickets that go before you think they will. If a holiday event is the reason you are coming, book it first and build the trip around that date. Everything else here is flexible. That is not.

Snow, and Why Portland Loses Its Mind Over Two Inches

You will read that Portland gets snow in December. Technically true. The whole year averages about 4 inches, and most of it arrives in January or February, not for Christmas.

When it does snow, the city stops. We sit in a valley, the hills are steep, we own very few plows, and a half inch of freezing rain on an inch of snow will close schools, strand buses and put a cross-country skier down the middle of a downtown street.

Two things follow. Do not plan a December trip hoping for city snow, the odds are bad. And if a cold snap does land while you are here, abandon your itinerary and go look at it, because a snowed-in Portland is a strange and lovely thing locals talk about for a decade. The pictures from one of those days are in this photo album of Portland in the snow.

If snow is the actual goal, drive to it. It is an hour east and up.

Day Trips That Still Work in the Dark Half of the Year

December is the wrong month for a lot of Oregon and the right month for a few specific things. Know the difference before you rent a car.

The waterfalls east of town run harder in December than any other time of year, for the obvious reason. All that rain has to go somewhere. The Columbia River Gorge is 30 minutes from downtown and the falls are at full volume, though parts of the historic highway and several trails close or ice over in winter. Check conditions the morning you go, not the night before.

Mount Hood is the other one. Ninety minutes from the city and reliably deep in snow when Portland has none, which is the trade this whole region runs on. My Mount Hood day trip guide has the routes and the chain rules, and you need to read the chain rules. Oregon enforces them.

The coast is the third option and a completely different trip. Storm surf, empty beaches, nobody in the tide pools. Ninety minutes to Cannon Beach, same shoes.

The Two Things I Talk People Out Of Every December

First, a downtown-only itinerary. I love this city and I will still tell you plainly that downtown Portland is rough in stretches, it is roughest in the dark, and December hands you fifteen hours of dark a day. Stay downtown if you like, the hotel value is real, but put at least half your days on the east side. Hawthorne, Alberta, Division. You will have a better time and meet more of us.

Second, the multi-region road trip. A common December plan crams Portland, the Gorge, the coast, Bend and Crater Lake into five days. Crater Lake in December means deep snow, closed roads and a long drive for a view you might not get. Pick one direction out of Portland and do it properly. Not both, not in the shortest days of the year.

So Was December a Mistake

No. Sit back down.

December takes two things from you, sunlight and dry feet, and hands back the city at its cheapest and least crowded, waterfalls at full roar, a garden built for rain, and the only weeks of the year when a Portland restaurant will look up and say sure, we can do that. If the trip you wanted was blue sky over Mount Hood and a patio on the river, come in July and I will not pretend otherwise. If you want the version of this place the rest of us actually live in, you booked correctly.

Come in the first three weeks if you can, keep two indoor anchors on every day, and quit reading the forecast. It is going to say rain. It is December in Portland. It is supposed to.

And the small expensive mistake you were worried about at midnight? That was booking the week between Christmas and New Year’s without a hotel reservation. Go do that now. Everything else takes care of itself.

Until next time,
