Pollen Forecast for Riverdale, California

The amount of pollen in the air for Saturday will be falling in the moderate range. The cause for the falling pollen levels is rising humidity, weak winds and expected precipitation in the morning, afternoon and evening which tends to wash pollen out of the air. With this amount of reduction in pollen levels, tomorrow should be better for allergy sufferers.

Concentration of pollen grains in the air for Sunday will be higher than they were today in the moderate range. This results in part from higher temperatures and the lower dewpoint. If you do suffer from allergies tomorrow could be more difficult.
