About pollen in Seattle

Tree pollen is the main contributor to today's count in Seattle, though it remains low and should go unnoticed by most people. Weed pollen is present in only trace amounts, so overall conditions are mild and manageable for the vast majority of allergy sufferers. Looking ahead, tree pollen is expected to hold steady at a low level over the next couple of days, with weed pollen staying similarly quiet. This lines up with the seasonal pattern for late September, as the region's oak, maple, ash, and plane trees have largely wound down their pollen release, and grass pollen is well past its peak. Any lingering sensitivity this time of year tends to come from weeds rather than trees, but even that influence looks minimal for now.
