Acer macrophyllum
Very low today, mostly grass pollen.
Last updated July 20, 2026
Pollen levels in Beaverton are quite low today. Tree pollen is absent, and grass pollen is only barely present, so most people should be able to go about their day without much irritation, even those who are typically sensitive. Looking ahead, conditions are expected to stay calm, with tree pollen remaining absent and grass holding at a very low level over the next stretch of days. This fits the season, as trees like maple, beech, and flowering pear have already finished releasing pollen for the year, and grasses are winding down from their late spring and early summer peak. For now, allergy sufferers in the area can expect a quiet, easy stretch of weather for breathing easy outdoors.
