About pollen in Trenton

Weed pollen is the only category active in Trenton today, and it remains at a low level. Most people should get through the day without much irritation, though those who are especially sensitive to ragweed and similar late-season weeds may notice mild symptoms during extended time outdoors. Looking ahead, weed pollen is expected to tick up slightly over the next several days, moving into a moderate range that could be more noticeable for allergy sufferers. This lines up with the typical seasonal pattern, as ragweed and other weeds tend to peak in late summer and stretch into fall before cooler weather sets in. Tree pollen from species like oak and maple is not a concern at this point in the year, since that season runs in spring, and grass pollen has already wound down from its late spring and early summer high.
