Eugene, Oregon – Summer heat makes a confident return to the Willamette Valley Tuesday as temperatures climb to 84°F by mid-afternoon in Eugene, with mostly sunny skies and dry conditions expected through the rest of the week.
According to the National Weather Service, calm morning winds will shift northwest around 6 mph by midday Tuesday, pushing in clear, warm air. Temperatures will rise sharply from a cool overnight low of 54°F, creating a 30° daily swing. Local officials advise residents to limit outdoor activity during peak afternoon heat, stay hydrated, and wear sunscreen.
By midweek, Eugene and surrounding areas like Springfield and Creswell will see highs in the upper 70s to low 80s, with mostly sunny to partly cloudy skies. The I-5 corridor is expected to remain dry, ideal for travel, but heat buildup on road surfaces could impact tire pressure and engine temperatures during long drives.
Wednesday will bring a high of 77°F with light northwest breezes. By Friday, partly sunny skies return, with temperatures inching back up to 78°F. No rain is forecast through Saturday, though morning mist and patchy clouds could briefly reduce visibility before clearing by mid-morning each day.
