Portland, Oregon has a marine west coast climate with mild, wet winters and warm, dry summers. At Portland International Airport, the 1991-2020 reference averages range from a daily high of 47°F (8°C) in Dec to 82°F (28°C) in Aug. Monthly precipitation averages sum to 36.9 inches (938 mm) per year.
The dry season (July-September) brings clear skies and stunning Cascade views. Fall transitions to steady rain by November. Winters are gray and damp, with infrequent but disruptive snow and ice events. Spring is slow to warm but explodes into bloom by April.
Portland can experience damaging freezing rain when cold air from the Columbia Gorge remains near the ground beneath warmer air aloft. Liquid drops become supercooled and freeze on contact with cold surfaces, coating roads, trees, and power lines with ice.
Local Planning Guide
Portland's main windows are the wet, gray season from November through May, rare ice and snow events, and late-summer smoke and heat.
Gorge winds and terrain create sharp local differences, so radar and alerts help separate rain, freezing rain, and snow across the metro.
