California pollen forecast by region
California allergy conditions vary sharply between coastal, inland, and valley regions. Someone searching for a California pollen forecast may be comparing Los Angeles, San Diego, Sacramento, San Jose, or San Francisco because each area has different vegetation, moisture patterns, and seasonal timing.
Tree pollen may rise in spring, grasses can become more active in late spring and early summer, and dry inland conditions may extend irritation for sensitive allergy sufferers. Checking California pollen counts by city helps account for regional microclimates rather than relying on one statewide pattern.
