Eugene, Oregon – A punishing wave of summer heat is set to grip Eugene this weekend, with temperatures soaring to 94°F by Saturday, July 12. Residents and drivers along I-5 and Highway 99 should prepare for hot pavement, sun glare, and rising health risks as the city enters a string of high-90s days. Avoid strenuous outdoor activity in the afternoon, hydrate regularly, and never leave pets or children in parked cars.
According to the National Weather Service in Portland, the heat will build throughout the weekend, reaching 94°F Saturday and peaking at 95°F Sunday. The Willamette Valley will remain locked in a sun-drenched pattern, with clear skies each night and only modest relief as temperatures dip to the low 60s. By Monday, expect a brief reprieve with a high near 90°F before temperatures surge again. Tuesday brings the week’s peak, with Eugene projected to hit 97°F—among the hottest readings so far this July.
Lane County travelers, especially those driving on I-5 or Hwy 99, should watch for heat-related vehicle issues. High temperatures can increase the risk of tire blowouts, engine overheating, and dehydration for anyone on the road or working outdoors. Public health officials urge everyone to drink extra water, limit midday activity, and use sunscreen.
The heat streak holds strong through at least Wednesday, with highs remaining above 95°F for much of the week. Check in on vulnerable neighbors and stay tuned for any updated advisories. Relief may not arrive until late next week.
