Eugene, Oregon – Another scorcher is on the way for Eugene, with temperatures climbing back near 90° by mid-afternoon Wednesday, July 30th. Residents should limit strenuous outdoor activity between 3 and 6 p.m. as the combination of heat and dry conditions increases the risk of dehydration and fire danger.
According to the National Weather Service in Portland, calm winds will shift slightly northwest by late afternoon as skies remain mostly sunny. No precipitation is expected, but relative humidity may dip below 30%, triggering elevated fire weather concerns across Lane County. I-5 travelers through Eugene should keep water on hand and avoid parking on dry grass to reduce fire risk.
While Wednesday’s high of 90° keeps Eugene in peak summer mode, slightly cooler air arrives Thursday, with a high of 83° and light northwest winds. By Friday, July ends on a bright note with sunny skies and a high near 87°. Saturday stays dry with highs in the mid-80s, continuing Eugene’s stretch of stable, summer-perfect weather.
Despite the heat, no formal heat advisory has been issued. Still, locals are encouraged to hydrate, check on vulnerable neighbors, and avoid peak sun hours this week.
⚠️ Next Update: A pattern shift could emerge next Monday with slightly cooler temps — stay tuned for changes.
