Saturday, April 25, 2026 — Portland rolled out of bed to crystal-clear skies and a brisk 39°F early this morning, with a few sheltered hollows still clinging to frost before sunrise. Sunshine will take over quickly, pushing inland neighborhoods into the upper 60s this afternoon, while overnight lows slip back into the mid-40s.
Sunny Weekend With Frost Risk Early
Both Saturday and Sunday are shaping up mostly sunny, with a high near 69°F today and around 70°F on Sunday. Overnight lows will bottom out near 44°F. Frost advisories remain in effect for some valley hollows until 9 a.m. PDT Saturday, April 25, 2026, so if you have tender plants, this is the morning to throw a cover over them, according to the National Weather Service Portland.
Small Rain Chances Monday–Tuesday
A couple of weak Pacific disturbances are lurking for late Monday into Tuesday, bringing a slight chance of light showers. The best odds are over the Cascades, with only a 10–20% chance along the I-5 corridor. Highs dip into the low to mid-60s early next week. That midweek trend has already been flagged in local coverage as the pattern shifts, including an April 19 look at how Portland could crank up to the upper 70s before midweek soaker.
Afternoon Winds And Marine Note
Afternoon north winds stay on the lighter side at about 3 to 8 mph, though it will feel breezier along more exposed coastal and riverfront spots. Out on the water, mariners should plan for seas of 5–7 ft with a northwest swell hanging on into next week. For full timing and marine details, check the latest from the National Weather Service Portland.
In practical terms, you can keep those patio and park plans, but protect sensitive plants and hold off on rolling up hoses until after the 9 a.m. advisory expires. Roads should stay dry for the afternoon commute. If you are heading to the river or ocean, secure loose gear and pull the most recent marine forecast before you launch.
