Thursday, April 23, 2026, started on the gray side in Portland, with clouds hanging low and the thermometer at Portland International Airport sitting around 48°F. Skies are expected to clear through the day, with temperatures making a run into the low 60s by afternoon. Light southerly breezes should swing around to the northwest, setting up a noticeably drier end to the week compared with those midweek showers.
Afternoon Sun And A Quick Warm-Up
Forecasters are calling for mostly sunny skies Thursday afternoon, a high near 63°F and light west-southwest winds around 5 to 6 mph. Friday keeps the warm-up going with more sun, highs near 69°F and some gusts possible late in the day. Overnight lows will still drop into the low to mid 40s, so tender plants and early-morning commuters are not done with the chill just yet, according to the National Weather Service.
Marine Conditions
Out on the water, conditions that were rough earlier in the week are slowly backing off. Small Craft Advisories remain in effect for some coastal waters and the Columbia River Bar, but they are expected to ease by 5 PM PDT Thursday as swells decrease. Boaters and paddlers are still urged to delay nonessential trips until the seas calm down and to check the latest marine forecasts before heading out.
Weekend Outlook
Warm, mostly dry weather holds into the weekend, with highs in the upper 60s to around 70°F on both Saturday and Sunday and only a small chance of isolated afternoon showers over the Cascades. Coverage of the midweek hazardous-seas episode came on April 22; today’s quieter update reflects calmer conditions and a short-lived warm stretch across the metro.
