Pollen Forecast for Copalis Beach, Washington

Based on past pollen counts and expected weather conditions, pollen levels for Friday will be on the increase in the moderate range. Since the weather has a major influence on pollen dispersal, this increase is due in part to drier air. The increase of this magnitude could make it more difficult for those with allergies.

Concentration of pollen grains in the air for Saturday will be falling into the very low range. This decrease is due to rising humidity and expected precipitation in the morning, afternoon and evening which tends to wash pollen out of the air.
