Memorial Day weekend weather in Oregon: mixed bags ahead

Oregon’s Memorial Day weekend plans just got a little more complicated. Forecasters expect a sunny start, with warm temps in the upper 70s to low 80s on May 22-24 across parts of the state. But by the time the holiday hits, a shift is coming—cool rain will move in, ending the warmth. The Willamette Valley will feel the difference first. While May 22-24 stays unusually warm—about 8 to 10 degrees above normal—the change arrives fast. Rain starts late on May 24, with heavier downpours expected May 25. Temps will drop into the 60s and then the 40s overnight, making outdoor plans chilly.Mountain travelers need to brace for even rougher conditions. Snow levels are dropping by May 25, hitting around 6, 500 feet, which means higher passes could see a mix of rain and snow. Even without snow, the cold and wet weather will make camping feel miserable. Backpackers hoping to kick off summer in the Cascades might be better off waiting. The coast isn’t spared either. A sneaker wave warning is in place for May 24, a reminder that Pacific waves can surge without warning. Beachgoers should stay alert—ocean conditions won’t be friendly.
