Eugene, Oregon – A relentless stretch of summer heat is holding Eugene in its grip, with temperatures set to soar back into the 90s by Thursday, July 17th. Anyone venturing outdoors or traveling on I-5 through the Willamette Valley should brace for another round of intense sun and lingering haze, especially after Wednesday’s near-record highs and smoke-filled skies.
According to the National Weather Service, Eugene faces a heat advisory through 10 p.m. Wednesday, but high temperatures will remain a concern as sunny, dry conditions persist. Thursday’s forecast calls for a high near 91°F with light winds and air quality impacted by lingering haze and smoke. These conditions can be dangerous for sensitive groups, children, and outdoor workers. Residents should avoid strenuous activities during the hottest hours, stay hydrated, and check on neighbors who may need assistance.
Friday offers little relief, with sunny skies and highs near 92°F. While temperatures dip slightly into the mid-80s for the weekend, the pattern stays dry and sunny, bringing fire danger concerns and continued risks for heat-related illnesses. Increasing clouds Saturday night hint at a modest cool-down, but Monday and Tuesday bring more sun and highs back in the upper 80s.
Travelers along I-5 and local roads should watch for reduced visibility in haze and take extra precautions for overheating vehicles. Emergency managers urge everyone to limit time outdoors, charge devices, and have backup cooling options ready as the region endures this prolonged heat stretch.
Warnings and advisories may be extended or reissued if conditions persist.
