Pollen in Westminster, CO

About pollen in Westminster

Pollen activity in Westminster is quiet today, with tree pollen sitting at essentially none. Anyone who typically reacts to airborne allergens should find the air calm and easy to manage, with little chance of symptoms tied to pollen. Looking ahead, conditions are expected to stay this way over the next several days, with tree pollen remaining absent. This fits the season well, since mid-November falls outside the active growing period for local trees like plane, pear, hackberry, crabapple, and lilac, all of which typically release pollen in spring rather than late fall. Grass and weed pollen also tend to wind down this time of year, so overall relief from pollen-related irritation should continue for now.

What to do today

• Pollen is minimal today, so it's a great time to be outside.
