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

Tree pollen starts early — alder, birch, and oak are primary triggers.
