Pollen Forecast for Sonoma, California

Pollen concentrations for Sunday will be on the increase in the moderate range. This increase is due to seasonally normal weather conditions which are favorable for the production and dispersal of pollen.

Since the weather has a major influence on pollen dispersal, this decrease is due in part to rising humidity, weak winds and expected precipitation in the morning and evening which tends to wash pollen out of the air.
