Portland, Oregon weather today is mostly cloudy with a high near 75°F and a 30% chance of light rain developing after 5 PM, according to the National Weather Service. It’s a classic spring day in the Rose City—pleasant enough to get outside early, but keep an umbrella handy for tonight.
Your Monday Game Plan
The morning and early afternoon are your window of opportunity. If you’re planning a walk along the Waterfront Park or a run on the Springwater Corridor Trail, aim for before 5 PM when the rain chances tick up. The light winds (2–7 mph from the west-northwest) mean no wind advisory headaches, so it’s actually a pretty nice day to be out. Temperatures will peak around 75°F mid-afternoon before dropping to around 72°F as clouds thicken.
For those thinking about yard work or lawn care in the Laurelhurst, Eastmoreland, or Irvington neighborhoods, Monday morning is ideal. If you’re planning to fertilize your spring lawn, today’s the day—rain won’t arrive in meaningful amounts until after sunset.
Tonight & Tuesday: Wet Weather Arrives
The National Weather Service forecasters are watching a closed low-pressure system drifting in from the Pacific. By Monday evening around 5 PM, light rain becomes likely, with a 50% chance of precipitation overnight. Expect a tenth to quarter-inch of new rainfall—nothing severe, but enough to cancel any outdoor dinner plans at the Pittock Mansion overlook or along the Columbia River Gorge.
Tuesday is the real wet day. Rain becomes likely (60% chance) with highs only reaching 62°F. This is a good day to catch a movie in the Pearl District, visit the Portland Art Museum, or work from home if you can. The rain should be light and steady rather than heavy, so no flash flood concerns for our area (the Weather Prediction Center marginal risk is focused on Northern California’s burn scars).
If you’re dealing with spring allergies—and let’s be honest, April in Portland means pollen season is in full swing—the rain Tuesday will actually help clear some of that pollen from the air. That said, a HEPA air purifier can help keep your indoor air clean, and an allergy relief nasal spray might make those rainy indoor days more comfortable. A pollen count face mask is also worth having on hand if you need to run errands during peak pollen hours Monday morning.
Looking Ahead
The good news? High pressure rebuilds starting Thursday, bringing a return to drier weather and warming temperatures through the weekend. By Friday and Saturday, we’re back to that classic Portland spring vibe—mild, mostly dry, and perfect for weekend plans.
For tonight’s dinner, a warm pasta or stir-fry pairs perfectly with this transitional weather. Comfort food before the rain rolls in feels just right. Did you know you can order groceries on Amazon? Get everything you need for tonight’s dinner delivered straight to your door.
Bottom line: Enjoy Monday morning and early afternoon outdoors, but have a plan for rain after 5 PM. Tuesday will be the wettest day of the week, so save indoor activities for then.
