Pollen Forecast for Placentia, California

Today
The amount of pollen in the air for Tuesday will be rising in the moderate range. This higher level is caused in part by seasonally normal weather conditions which are favorable for the production and dispersal of pollen. This heavy increase in pollen concentration could very well cause problems for those who are allergic to airborne pollens.
Outlook
Pollen concentrations for Wednesday will be falling into the extremely low range. This relief in pollen levels is caused in part by heavy rains in the morning, afternoon and evening which tend to wash pollen out of the air.
