Rochester Pollen Report
Rochester's Lake Ontario shoreline and Genesee River valley shape a compressed but intense allergy season. Birch — one of the most allergenic pollens anywhere — explodes across the metro each May, oak and maple follow, and grasses and ragweed carry the summer. Lake-fed humidity keeps mold active well into fall.
