Portland rolled into Monday with clear skies and a crisp 61°F at Portland International Airport (KPDX), and the city is set to keep that sunny streak going through the afternoon. Inland highs will climb to around 84°F under bright blue skies, with a light southwest breeze generally staying under 10 mph. Along the coast, it is a different story, with cooler temperatures and only a very small chance of measurable rain today.
Afternoon Sunshine
Meteorologists at the National Weather Service Portland expect most Willamette Valley neighborhoods to land solidly in the mid 80s, while coastal towns linger in the 60s. Skies around the metro should stay mostly sunny, with just a tiny chance of drizzle and afternoon winds in the 3 to 6 mph range. It is a solid day for tackling outdoor errands or sneaking in a park walk, though any coastal trip will feel noticeably cooler.
Coastal Drizzle Possible Tuesday
On Tuesday, a weak front is forecast to brush the coast, bringing the best shot at light rain or drizzle to north Oregon beaches and the Coast Range. Portland and the rest of the I-5 corridor are expected to stay mostly dry. Forecasters note that chances for coastal moisture increase the farther north you go, so beach plans north of Cannon Beach come with a higher risk of mist or light showers. If you are heading for the sand, a light jacket would be a smart add to the bag.
Warmest Day Friday
Temperatures trend up later in the week, with inland highs topping out in the upper 80s by Friday, which currently looks like the warmest day of the stretch. Forecast discussions flag a modest heat risk for urban and suburban neighborhoods that day, so anyone without reliable cooling should keep an eye on conditions and try to avoid strenuous outdoor activities during the hottest afternoon hours.
Commuter Notes
Morning low clouds and patches of stratus may hang on in low-lying corridors before clearing by midmorning, leaving early commuters with a cooler, grayer start than the sunnier afternoon will suggest. On the water, boaters and mariners can expect seas around 4 to 6 feet with a dominant west-northwest swell, along with the potential for breezier northerly winds later in the week.
