Pollen Forecast for Phoenix, Arizona

The quantity of pollen grains in the air for Friday will be higher than they were today but will still remain in the low range. This higher level is caused in part by seasonally normal weather conditions which are favorable for the production and dispersal of pollen.

The amount of pollen in the air for Saturday will be falling in the low range. The cause for the falling pollen levels is rising humidity, weakening winds and expected precipitation in the morning which tends to wash pollen out of the air.
