Eugene, Oregon – Summer heat is bearing down on the Willamette Valley this week, with Eugene expected to hit 93°F by Wednesday afternoon — the hottest day of the week — under a streak of clear skies and dry conditions.
According to the National Weather Service in Portland, high pressure building over western Oregon will keep temperatures in the upper 80s to low 90s through Friday, with sunny days and calm winds persisting. A light north wind between 5 and 7 mph will offer little relief during peak afternoon hours.
Eugene will see highs near 88°F today, rising to 90°F on Thursday. Nighttime lows will drop to the mid-to-upper 50s, providing only minimal overnight cooling. Visibility remains strong at 10 miles, but early-morning fog is possible, especially around low-lying areas near the Willamette River.
Lane County residents are urged to stay hydrated, limit outdoor activity during peak heat (2–6 p.m.), and check on neighbors without air conditioning. Schools and public services may remain open, but cooling centers could be activated if the heat intensifies.
This July heat wave is expected to ease slightly by Saturday, with highs dipping back into the mid-80s. However, no rain is forecast through early next week.
