Eugene, Oregon – A streak of scorching weather returns to western Oregon this Friday, July 18th, as Eugene braces for another 91°F high — the second in as many days. With dry skies, minimal wind, and very little overnight cooling, residents should prepare now for elevated daytime heat that could affect health, power use, and weekend outdoor plans.
According to the National Weather Service in Portland, temperatures in Eugene will peak around 91°F again on Friday, with calm winds becoming northwesterly near 6 mph by afternoon. Conditions remain mostly clear into Friday night, with a low around 55°F. The heat trend continues into Saturday, with highs near 86°F under sunny skies.
The extended outlook keeps temperatures in the mid-80s through early next week, with gradual warming again by Wednesday.
