Pollen in Baltimore, MD

About pollen in Baltimore

Pollen is essentially quiet across Baltimore today. Tree pollen is registering as none, and there is no indication of grass or weed activity either, so anyone prone to seasonal allergies should get a bit of a break. If you have been dealing with irritation lately, today's air is unlikely to be the cause. Looking ahead, tree pollen is expected to stay at this low level over the next several days, which fits the season — the region's oaks, ginkgos, magnolias, crepe myrtles (Lagerstroemia), and smoketrees (Cotinus) already had their heavier pollen release earlier in the year and are largely finished for now. Late summer in Baltimore tends to be calmer on the tree front, with attention typically shifting toward weeds like ragweed as autumn approaches, though there is no sign of that starting yet.
