About pollen in Dayton

Grass pollen is the only type registering in Dayton today, and levels are running very low. Most people, including those with sensitivities, should notice little to no irritation outdoors this afternoon or evening. Looking ahead, grass pollen is expected to hold steady at this low level over the coming days, so no significant changes are anticipated in the near term. This is a fairly typical lull for late July in the region — the heavier grass season has largely passed, tree pollen from maples, oaks, and other regional species finished releasing back in spring, and ragweed season has not yet arrived. For now, outdoor conditions remain generally comfortable for allergy sufferers.
