Pollen in Eugene, OR

About pollen in Eugene

Grass pollen typically dominates the Willamette Valley through midsummer, and by late July it is usually beginning to ease as the peak growing season winds down. For most residents, this stretch tends to bring only mild, intermittent irritation, with sensitive individuals occasionally noticing symptoms on warm, dry, or breezy days when grasses release more pollen into the air. Looking ahead, expect the gradual seasonal shift to continue: grass activity should keep tapering off through the coming days, while tree pollen from species like oak, alder, and birch remains quiet this time of year after their spring peak. Ragweed and other late-summer weeds are not yet in full swing in this region, though they can begin to appear as August approaches, so it is worth keeping an eye on how conditions evolve in the weeks ahead.
