Antioch's allergy season varies with proximity to the coast. Coastal breezes help, but residents of Antioch, CA can still experience significant pollen from February through October, especially during dry, warm spells.
Right now: August brings weed pollen to Antioch and the start of wildfire season affects air quality.
Spring
