Low Pollen in Westminster, CO

About pollen in Westminster

Tree pollen is the main contributor to today's count in Westminster, though it remains at a low level overall. Weed pollen is present but only barely, registering at a very low level. For most people, today should be an easy day to be outside, with little to no irritation expected even for those who tend to react to tree pollen. Looking ahead, tree pollen is expected to hold at this same low level, while weed pollen should stay quiet through the next several days as well. This is a bit of an unusual stretch for late September, since tree pollen from species like ash, maple, oak, cottonwood, and thuja typically finishes up well before now, with weeds such as ragweed normally taking center stage this time of year. The overall calm conditions suggest a comfortable window before any seasonal shifts bring more noticeable pollen activity.
