Eugene, Oregon – Triple-digit heat and lingering haze will grip Lane County Wednesday, with temperatures nearing 98°F by mid-afternoon across Eugene. Areas of smoke and air stagnation could return by mid-morning, increasing health risks and visibility concerns along I-5 and surrounding highways.
According to the National Weather Service, widespread haze is expected to develop after 10 a.m. Wednesday, with sunshine pushing high temps toward the upper 90s. Winds will remain light throughout the day, reducing smoke dispersion and raising air quality concerns for vulnerable groups. Northbound travelers on I-5 through Eugene may experience hazy conditions and reduced visibility from late morning through sunset.
Residents should avoid prolonged outdoor activity, stay hydrated, and use air conditioning or clean air spaces if possible. Wednesday’s high marks one of the hottest days this summer so far, but the relief is coming. By Thursday, temps drop slightly to 90°F with sunny skies and improved air quality.
Looking ahead:
- Thursday (High: 90°F) – Sunny, calmer air, low smoke impact
