Portland woke up to clear skies and mild air on Sunday, April 19, 2026, with temperatures hovering near 52°F at PDX. If it felt like a soft launch into spring, that is because it was, with a swift warm-up on tap into the mid-to-upper 70s this afternoon, especially for inland spots around the Portland metro.
Sun will run the show for most of the day and winds should stay on the mellow side, generally under 5 mph from the east-northeast through the afternoon. If you are heading west, expect a different vibe along the coast and over the Coast Range, where highs will stall in the noticeably cooler low-to-mid 60s.
Midweek Rain and Cooler Temperatures
Enjoy the warmth while it lasts. A Pacific low sliding toward the coast is set to shuffle the pattern, bringing increasing clouds and a chance of rain late Monday, April 20, 2026. Steadier showers are likely Tuesday into Wednesday, April 21–22, 2026, according to NWS Portland. Forecasters say most lowland rain totals through Wednesday should land around 0.25 to 0.75 inches, with higher amounts piling up in the Coast Range and Cascades.
Timing and Commute Impacts
Light rain could sneak in Monday evening, but the better bet for measurable showers arrives Tuesday morning and continues through midweek as daytime highs drop back into the 50s. Translation for commuters: expect wet roads for both the morning and evening drives on Tuesday and Wednesday, and plan on grabbing a rain jacket if you have outdoor plans beyond Monday.
Boaters and Outdoor Plans
Mariners should keep an eye on the forecast for increasing onshore flow and building seas by midweek, as very strong ebb currents at the Columbia River Bar continue each morning through Tuesday. There are no watches or warnings in effect for the Portland metro right now, but conditions could become marginal for small craft late Wednesday if the incoming system behaves as expected.
