Pollen Alerts For Washington, DC

Pollen Index: 11 Pollen Level: high Predominant Pollen: Maple, Elm and Cedar/Juniper. The amount of pollen in the air for Thursday will be falling but will remain in the high range. Since the weather has a major influence on pollen dispersal, this decrease is due in part to falling temperatures, rising humidity, and heavy rains in the morning and evening which tend to wash pollen out of the air. With this amount of reduction in pollen levels, tomorrow should be better for allergy sufferers.
