Pollen Forecast for Penryn, California
Today
The amount of pollen in the air for Thursday will be rising in the moderate range. Since the weather has a major influence on pollen dispersal, this increase is due in part to drier air. This heavy increase in pollen concentration could very well cause problems for those who are allergic to airborne pollens.
Outlook
Pollen concentrations for Friday will be at about the same level in the moderate range. If you do suffer from allergies, tomorrow should be about as difficult outdoors as it was today.
