Acer macrophyllum
Very low today, mostly tree pollen.
Last updated August 15, 2026
Pollen levels around Beaverton are quiet today, with both tree and weed sources registering very low. This is a mild stretch, and most people should move through the day without any noticeable irritation from what's in the air. Looking ahead, tree pollen is expected to fade further over the next few days, essentially disappearing as the region moves past the active season for trees like maple, beech, katsura, pine, and styrax. Weed pollen, on the other hand, is set to tick up slightly from very low to a mild-moderate level and hold there through the week, a typical pattern as late summer weeds become the more prominent source of pollen while trees and grasses take a back seat.
