Pollen Forecast for Friday Harbor, Washington

The amount of pollen in the air for Thursday will be falling in the low range. This forecast of lower pollen concentration is based on rising humidity, weak winds and expected precipitation in the morning, afternoon and evening which tends to wash pollen out of the air.

Concentration of pollen grains in the air for Friday will be higher than they were today in the moderate range. This rise is a result of seasonally normal weather conditions which are favorable for the production and dispersal of pollen. If you do suffer from allergies tomorrow could be more difficult.
