Pollen Forecast for Grapevine, California

The quantity of pollen grains in the air for Friday will remain relatively stable in the low range. No change doesn't mean no pollen, it just means that pollen producing plants are delivering pollen at a steady pace.

The amount of pollen in the air for Saturday will be falling into the extremely low range. Since the weather has a major influence on pollen dispersal, this decrease is due in part to rising humidity, weak winds and expected precipitation in the afternoon which tends to wash pollen out of the air.
