Pollen Forecast for Ashburn, Virginia

The quantity of pollen grains in the air for Friday will be greater than today's levels but will still remain in the low range. This forecast of higher pollen concentration is based on higher temperatures and the lower dewpoint. If you have these allergies, tomorrow will likely be more difficult outdoors.

Pollen concentrations for Saturday will be falling into the extremely low range. This lowering of pollen concentrations is a result of falling temperatures, rising humidity, and expected precipitation in the afternoon and evening which tends to wash pollen out of the air.
