Pollen Forecast for Santa Clara, California

Based on past pollen counts and expected weather conditions, pollen levels for Thursday will be falling into the extremely low range. The cause for the falling pollen levels is rising humidity, weak winds and expected precipitation in the morning and evening which tends to wash pollen out of the air.

The quantity of pollen grains in the air for Friday will be higher than they were today but will stay in the very low range. Since the weather has a major influence on pollen dispersal, this increase is due in part to strong winds and decreasing humidity.
