Acer macrophyllum
Very low today, mostly tree pollen.
Last updated September 30, 2026
Pollen levels in Beaverton are quiet today, with both tree and weed sources reading very low. Anyone sensitive to allergens should notice little to no irritation, making this a comfortable day to spend time outdoors without much concern about pollen triggers. Looking ahead, weed pollen is expected to hold steady at a very low level over the next several days, and tree pollen should remain minimal as well. This lull fits the season well: local trees such as maple, beech, katsura, pine, and styrax finished their peak release back in spring, and with weed pollen typically tapering off through the fall, conditions are likely to stay mild in the near term.
