No notable pollen right now.
Last updated July 28, 2026
Beaverton is enjoying a quiet stretch on the pollen front today. Tree pollen, the only category being tracked at the moment, is essentially absent, so anyone sensitive to maple, cherry and plum relatives (Prunus), beech, katsura, or pear trees should notice little to no irritation from that source right now. Looking ahead, this calm pattern is expected to hold over the next several days, with tree pollen staying at negligible levels. This tracks with the season: local trees typically release their heaviest pollen in spring, so by late summer their contribution has largely wound down. If grass or weed pollen becomes relevant later on, that would align more with the late-summer and fall pattern, but for now the air around Beaverton looks clear on the tree front.
