Pollen in Westminster, CO

About pollen in Westminster

Pollen levels in Westminster are quiet today, with tree pollen essentially absent from the air. Anyone who has been dealing with allergy symptoms lately should get a bit of a break, as conditions are calm across the board right now. Looking ahead, tree pollen is expected to stay low over the next few days, so no significant changes are on the horizon. This tracks with the season, since trees like Plane, Pyrus, Celtis, Malus, and Syringa typically finish their pollen release well before midsummer. With summer in full swing, keep in mind that grasses can still be active this time of year, and ragweed season will follow later in the summer into fall.
