We know the question on your mind, Portlanders — when’s it going to snow again? Thanks to the National Oceanic and Atmospheric Administration’s Climate Prediction Center, we know what temperatures and precipitation trends to expect in our city for December, January, and February. While exact weather conditions typically can’t be predicted more than a week in advance, here’s a seasonal outlook to help you prepare for what winter will bring.
Reminder: The first day of winter is Thursday, Dec. 21.
Temperature
Think warm. This winter, Portland has a 33-40% chance of temperatures being lower than normal.
Precipitation
Keep your rain jacket close. Portland has slightly higher chances of seeing above-average snow and rainfall totals this winter.
Dive into December
Generally, December is the wettest month of the year in Portland, with an average of 5.77 inches of precipitation. However, climate scientists predict there is a 57% chance that La Niña conditions arrive this winter, which historically keeps things rainier in Oregon.
January is just cold
During this month, the average high and low temps are between 47.5° and 36.2°. And if that La Niña holds up, we might also see some really nice snow pack in the mountains. We’re crossing our fingers for local ski resorts.
February feels frozen
Average temperatures fluctuate between 51.5° and 36.8° throughout February, which makes it an ideal time to enjoy indoor events like the Portland Jazz Festival. You may have love in your eyes, but you won’t have to worry about the sun — the average UV index of 2 poses a low threat to health.
