About pollen in Baltimore

Weed pollen is the main contributor to today's overall low levels in Baltimore, though it remains fairly mild and shouldn't cause much trouble for most people. Tree pollen is barely present, a typical state for midsummer when species like oak, ginkgo, magnolia, and crape myrtle (Lagerstroemia) have long since finished releasing their pollen for the season. Looking ahead, conditions are expected to stay much the same through the next several days, with tree pollen remaining negligible and weed pollen holding at a low level, dipping slightly at times. This lull is normal for mid-August, a quiet stretch between the spring tree season and the ragweed surge that typically arrives later in the fall. For now, sensitive individuals should notice little disruption from either category.
