About pollen in Aurora
Weed pollen is running high in Aurora today, and it is the main driver of allergy discomfort right now. Anyone sensitive to ragweed and similar late-season weeds should expect noticeable symptoms, particularly during outdoor activity in the afternoon. This is a day when it makes sense to be mindful of prolonged time outside if you tend to react to weed pollen. Looking ahead, weed pollen is expected to stay high for the next couple of days before easing slightly to a more moderate level by midweek. This pattern fits the season well, as late September is peak time for ragweed and other weeds across the region, while tree pollen from species like oak and maple remains dormant until spring and grass pollen has already wound down for the year. Expect weed pollen to gradually taper off as the weeks progress and cooler, more consistent fall weather sets in.
