A quiet and pleasant Mother’s Day weekend in Portland
Portland, USAMon May 11 2026
Portland’s Mother’s Day weekend is shaping up to be a calm one. The forecast calls for soft breezes and partly sunny skies, with temperatures hovering around the low 70s during the day and dropping to near 50 at night. The air will feel gentle, moving at about 5 to 7 miles per hour from the north-northwest. By evening, clouds will thicken but should clear before morning.
The warmth sticks around for a few days after. Monday brings mostly clear skies and a high near 81 degrees, while Tuesday heats up even more, reaching around 87 degrees. Then, the pattern shifts. Late Tuesday night, there’s a slight chance of rain turning into thunderstorms after 11 p. m. The rest of the week looks mild—highs around 70 and lows near 50—with only a small risk of rain continuing.
Locals know Oregon weather can change fast, so this mild shift isn’t surprising. The state often sees quick transitions from sun to rain, especially in spring.
