Chinese elm
Ulmus parvifolia
Very low today, mostly grass pollen.
Last updated October 9, 2026
Pollen levels around Westminster are quiet today. Tree pollen is absent entirely, while grass and weed pollen are both present only in very small amounts. Most people, even those with sensitivities, should notice little to no irritation from pollen today. Looking ahead, conditions are expected to hold steady over the next several days, with grass and weed pollen staying at these low, barely noticeable levels and tree pollen remaining out of the picture. This fits the season, since local trees like Rhaphiolepis, Photinia, Tristaniopsis, Lagerstroemia, and Melaleuca typically release their pollen in spring rather than fall, and grass and weed activity this time of year tends to be on the milder side as well. For now, outdoor conditions should stay comfortable for those who deal with seasonal allergies.
