About pollen in Allentown
Weed pollen is the main story in Allentown today, sitting at a low level that most people will not notice much. Overall pollen in the area is light, so this is a fairly easy day for those with allergies, though anyone particularly sensitive to ragweed may still feel a mild effect. Looking ahead, weed pollen is expected to inch upward over the next several days, moving from low into the low-to-moderate range. This lines up with the season, as ragweed remains the dominant pollen source through late September and into fall, while tree pollen from species like oak and maple stays dormant until spring. If you tend to react to ragweed, it may be worth keeping an eye on symptoms as the week progresses.
