Pollen Forecast for Rancho Cucamonga, California
Medium
Oak, Mulberry, Ash
Discussion
Concentration of pollen grains in the air for Tuesday will be falling in the moderate range. This lower level is caused by rising humidity, weakening winds and expected precipitation in the morning and evening which tends to wash pollen out of the air.
Allergy Facts
Although most cereal crops are members of the grass family, many do not release significant amounts of pollen into the atmosphere and therefore do not cause hay fever.
