Portland, OR, August 6, 2026 —
PORTLAND, OR – Air quality in Portland is showing significant improvement as the lingering effects of recent wildfire smoke begin to clear. Conditions are anticipated to be largely free of smoke by Friday, offering residents a reprieve from the hazy skies and reduced air quality.
Despite the improving air, temperatures are expected to remain warm through the end of the week. Highs are forecast to stay in the 80s and low 90s on Thursday and Friday. However, a noticeable cool down is on the horizon for the weekend. Saturday is projected to see highs in the mid-80s, followed by temperatures in the lower 80s on Sunday.
Meanwhile, conditions east of the Cascade Mountains are prompting concern for fire weather. Red Flag Warnings have been issued for Friday and Saturday in these areas. The warnings are due to a combination of gusty winds and low humidity, which significantly increase the risk of fire ignition and the potential for rapid spread should any fires start.
Looking ahead to next week, Portland is expected to experience seasonable weather patterns. Temperatures are predicted to range from the lower to mid-80s, with a forecast that includes a mix of sunshine and cloud cover.
