Portland, OR, August 1, 2026 —
Portland, Oregon, is set to enjoy a reprieve from recent windy conditions with a calmer, cooler Sunday. Skies are expected to be mostly sunny, with high temperatures anticipated to reach the mid-70s. This milder weather serves as a prelude to a significant shift expected early next week.
Beginning Monday, temperatures are forecast to climb, with a heatwave predicted to grip the region. By Tuesday and Wednesday, highs are expected to soar into the upper 80s and potentially reach the low 90s. This marked increase in temperature signals a substantial departure from the more moderate conditions of Sunday.
In addition to the rising temperatures, residents west of the Cascade Mountains may experience hazy skies on Monday and Tuesday. This haze is attributed to the potential arrival of wildfire smoke. An anticipated shift in wind direction to an easterly flow could carry smoke from distant wildfires into the Portland metropolitan area.
The upcoming week’s forecast suggests a dynamic weather pattern, transitioning from a pleasant Sunday to significantly warmer temperatures and the possibility of reduced air quality due to smoke. Further updates on the intensity of the heatwave and the extent of smoke impacts are expected as the week progresses.
