Pollen in Longmont, CO

About pollen in Longmont

Pollen activity in Longmont is minimal right now, consistent with mid-November conditions. Cold temperatures and the late stage of the growing season mean trees, grasses, and weeds are all largely dormant, so most residents should find the air comfortable with little to trigger allergy symptoms. Looking ahead, this quiet stretch is expected to continue through the next several days, as Colorado's Front Range typically sees a lull in pollen activity through the winter months. The next notable shift usually comes in early spring, when trees such as cottonwood, elm, and juniper begin releasing pollen, followed by grasses in late spring and ragweed later in summer. For now, allergy sufferers can expect a seasonal break before that cycle resumes.
