Low today, mostly grass pollen.
Last updated July 1, 2026
Grass pollen is the main driver in Beaverton today, sitting at a Low level (2) and accounting for the overall Low reading of 2. Tree pollen has dropped to None, so local allergenic species like Pine, Maple, Prunus, Fagus, and Cercidiphyllum are contributing little to nothing right now. The forecast holds grass steady at Low through the next five days, with no notable rise or fall expected. This pattern fits the season, as the spring tree peak has passed and grass typically leads in late spring and early summer. Weed pollen has no data available for today or the forecast period.
