Portland in December – 2021 Events, Things to Do, and Weather

December in Portland is the coldest, wettest, and darkest month of the whole year. It’s a good thing we have the holiday season and outings to distract us. But of course, you will find some bluebird days in December. Proof is that I took this picture in December at a winery in the Willamette Valley. So here’s more information about visiting Portland in December – events, weather and the best things to do in Portland, Oregon at the start of winter.

Things to Do in Portland in December

We often forget that most of December is still technically fall. But if you’ve moved on to winter activities, that’s ok too. December is a busy time because of the holidays. Each year I try to do a Portland advent calendar with experiences and adventures around the city. Some of those things usually include seasonal ales and holiday events. Our favorite things to do in Portland, Oregon in December are Blazers games, Christmas shopping at all the popup markets, eating donuts (not strictly a December outing), picking out a Christmas tree, shopping for books at Powell’s Books and seeing all the downtown lights, and doing at least one Christmas tree lights outing (Peacock lane, Grotto, Zoolights etc). And if we get enough snow, a visit to Mt Hood National forest for some snowshoeing or just playing in the snow.

Portland Weather in December

Note: If you want to know about the weather you can visit a weather website. But one of the most frequent texts I get from friends about to visit Portland is about the weather. So that’s why I include this weather section. It’s how to interpret Portland weather forecasts by a local. :)

The weather in Portland [Oregon] in December is the coldest and wettest of the whole year! It’s also the darkest month of the year (along with January) with only 9 hours of total daylight per day and averaging a 4:30pm sunset. Sunrise moves from about 7:30am to 8am. So it’s dark when you leave for work and dark when you leave work. And they say “it’s the most wonderful time of the year?” Hmm… merry Christmas!?

The average December temperatures are highs in the mid 40s and lows in the mid 30s. Combined with the rainiest month of the year, and sometimes a surprise snow, December is definitely hello to winter. December averages 15 days of rain and 6.8″ of rainfall, with an occasional dusting of snow for a total of .8″ on average for the month.
