Pollen in O'Fallon, MO

About pollen in O'Fallon

Pollen activity in O'Fallon is minimal as the year moves deeper into November. With overnight temperatures dropping and most plants dormant, there is little in the air to trigger symptoms right now, and most residents should find outdoor conditions comfortable from an allergy standpoint. Looking ahead, this quiet stretch is typical for late fall in the region. Ragweed, which tends to linger into early autumn, has largely wound down, and the oaks, maples, and elms common to the area won't begin releasing pollen again until trees start budding in spring. Grass pollen follows later, typically peaking in late spring and early summer. For now, expect the lull to continue through the week, with any seasonal pollen return still months away.
