No notable pollen right now.
Last updated July 28, 2026
Pollen levels in Renton are quiet today, with tree pollen registering essentially absent. Anyone sensitive to airborne allergens should find little to react to outdoors right now, making this a comfortable stretch for spending time outside. Looking ahead, tree pollen is expected to remain minimal over the next several days, continuing the calm pattern currently in place. This tracks with the seasonal rhythm for the area, since trees like oak, dogwood (Cornus), hornbeam (Carpinus), and golden rain tree (Koelreuteria) release most of their pollen earlier in spring, well before midsummer arrives. With that season behind us, tree-related symptoms should stay low for now, though it's worth keeping an eye on grass and late-summer weeds as the season progresses.
