Navy Trench and Shorts
A navy trench coat over khaki bermuda shorts and a blue linen blouse works between seasons on a mild rainy day. Black pointed-toe heels sharpen what could easily be too casual.
What to Wear in Portland in March
In March, Portland averages highs of 56°F and lows of 40°F with about 14 rainy days — the Pacific Northwest's signature gray, drizzly spring weather. The Columbia River Gorge and Mount Hood are accessible but wet; waterproof layers are more important than warmth most March days. A quality waterproof jacket and waterproof walking shoes are the essential March gear, not a heavy coat.

Based on typical March conditions in Portland. Weather varies year to year — check the live forecast when you're within two weeks of your trip.
March in Portland is classic Pacific Northwest — highs averaging 56°F, lows at 40°F, and 14 rainy days of that signature drizzle that's rarely a downpour but persistently damp. The Columbia River Gorge is beautiful year-round and accessible in March, with fewer summer crowds at Multnomah Falls and the Historic Columbia River Highway. The Japanese Garden, Portland Art Museum, and Powell's City of Books are excellent indoor anchors on the many wet days. Portland's outdoor-creative aesthetic handles rain as a fact of life rather than an obstacle — the city's culture rewards waterproof gear that functions beautifully. A quality waterproof jacket (not an umbrella-dependent approach) is the essential March piece; comfort with mild temperatures means a heavy coat is usually overkill. Waterproof walking shoes handle the wet sidewalks and Columbia Gorge trail surfaces. The Pearl District and Mississippi Avenue walkable neighborhoods are excellent in any weather. Late March begins the transition toward the brief, spectacular Pacific Northwest spring.
