Portland, Oregon, sees a mild, damp winter and warm, dry summer, with the live forecast above showing today’s conditions. The city sits in the Willamette Valley, shielded from Pacific storms by the Coast Range, giving it a distinct rain-shadow effect compared to nearby coastal spots like Cannon Beach.
What is typical for Portland weather this season?
Portland’s weather varies sharply by season. Winters hover around 4°C to 9°C, with frequent drizzle and overcast skies. Summers, from June to September, are consistently sunny and dry, often reaching 27°C to 32°C. The region rarely sees extreme cold or heat, but the 14-day and 15-day outlooks often show a shift from wet to dry patterns in spring and autumn. For those checking Portland weather in Fahrenheit, expect winter lows near 40°F and summer highs around 85°F.
How does Portland compare to nearby areas?
Portland’s inland location means less rain than the coast. Cannon Beach weather, just 130 kilometres west, is cooler and wetter year-round, with frequent fog. Hood River weather, 100 kilometres east in the Columbia River Gorge, is sunnier and windier, especially in summer. Portland’s weather is a middle ground—milder than the gorge, drier than the coast.

Snow is rare in Portland, averaging only about 10 centimetres annually. Most winters see one or two light dustings that melt quickly, though occasional ice storms can disrupt travel.
What is the best time to visit Portland for good weather?
Late June through early September offers the most reliable sunshine and warmth, with daytime highs near 27°C. July and August are peak months for clear skies and low humidity.
How does Portland weather affect outdoor plans?
Spring and fall are unpredictable—pack layers and a rain jacket. Summer is ideal for hiking and cycling, but wildfire smoke from regional fires can occasionally reduce air quality in August.
