About pollen in Norwalk
Weed pollen is the main contributor to Norwalk's air today, though levels remain low. Most people should be able to go about their outdoor plans without much irritation, though those with heightened sensitivity to ragweed and similar late-season weeds may notice mild effects. Looking ahead, weed pollen is expected to stay low over the next couple of days before edging up slightly to a moderate level midweek, then easing back down. This pattern fits typical late-September conditions, as ragweed continues its usual fall run before tapering off with the season. Tree pollen from local species like oak and maple is not a factor at this point in the year, since those trees release most of their pollen in spring.
