Moderate Pollen in Westminster, CO

About pollen in Westminster

Grass pollen is the main driver in Westminster today, sitting at a moderate level on the Universal Pollen Index, while tree pollen has eased back to low. The five-day forecast shows grass holding steady at moderate throughout, so expect little change in the days ahead. Tree counts are projected to drop further to a consistently low reading, reflecting the typical late-spring decline of species like Ash, Maple, Oak, Thuja, and Cottonwood. This timing fits the season well, as grasses tend to peak in late spring and early summer just as tree pollen winds down. Ragweed and other weeds aren't tracked here yet, but those typically become a factor later in the summer and into fall.

What to do today

• It's important to shower and wash your hair after spending a lot of time outdoors.
