About pollen in Boulder

Mid-November in Boulder tends to be a quiet stretch for pollen, and today fits that pattern. With cold nights and dormant vegetation now the norm along the Front Range, the trees, grasses, and weeds that trigger most seasonal allergies are largely inactive. Anyone sensitive to pollen should find today comfortable, with little to no irritation expected from airborne sources. Looking ahead, this lull should continue through the next few days, as late fall conditions keep plants dormant and pollen production minimal. Boulder's tree season, driven by cottonwood, juniper, and elm, typically doesn't pick up again until late winter or early spring, while grass pollen waits until late spring and ragweed remains dormant until late summer. For now, residents can expect pollen levels to stay low as the region settles into its winter pattern.
