Pollen in O'Fallon, MO

About pollen in O'Fallon

Pollen activity in O'Fallon is quiet at the moment, with no single pollen type standing out as a concern today. For most residents, this should mean an easier day outdoors, with little in the way of typical seasonal irritation from trees, grasses, or weeds. Looking ahead, this stretch of late July typically falls in a natural lull for pollen in the region. The spring tree season, driven by oaks, maples, and other regional hardwoods, has long since passed, and grass pollen—usually most active in late spring and early summer—tends to taper off by now as well. Ragweed, the dominant late-summer and fall allergen in Missouri, has not yet ramped up, so conditions should remain fairly calm in the near term before that seasonal shift begins.
