Portland wakes up under clear skies today, and by afternoon the metro area will be basking in warm sunshine, with highs climbing to about 82. Later in the day, north winds start to kick up, adding a bit of breeze to the warmth. Tuesday looks even hotter, with mid‑80s expected across the valley and a 20–40% chance parts of the metro briefly spike toward 90. If you have outdoor plans, aim for the cooler morning or evening hours and bring water, and anyone sensitive to heat should make a cooling plan now rather than later.
Afternoon Winds Pick Up
Those north winds will increase this afternoon to roughly 3–9 mph, with inland gusts topping out around 18 mph. Along the coast and the Columbia River, gusts will be notably stronger. Small Craft Advisories are up for several marine zones from this afternoon into early Tuesday, so boaters and river users will want to think twice before assuming it is a calm summer float. All of that comes from the National Weather Service.
Tuesday Heat And Cooling Options
Tuesday is on track to be the warmest day of the week, with highs near 86 and forecasters calling for a 20–40% chance that parts of the Portland/Vancouver metro could reach or even edge past 90, which would trigger a Moderate HeatRisk for some neighborhoods. If you do not have reliable air conditioning, the city’s Cooling Portland program helps qualified residents get portable cooling and other assistance. It is a good day to check on older neighbors and anyone with health concerns, limit strenuous outdoor work during the peak heat of the afternoon, and keep water handy.
Late‑Week Showers Possible
Showers and a chance for a few thunderstorms return late Tuesday night into Wednesday as a Pacific trough moves in, although most spots are only expected to see light totals. Behind that system, daytime highs trend back into the upper 60s to low 70s later in the week, with breezier conditions along the coast and through the Gorge. If you are planning outdoor events, today and Tuesday are your better dry window, but have a backup indoor plan ready in case thunder or gusty winds materialize on Wednesday.
