Kiawe (Prosopis pallida)

Mold (Aspergillus, Cladosporium)

Why Allergies Are Worse in Honolulu
Honolulu lies on the leeward coast of Oahu where the Ko'olau Range blocks moisture-laden trade winds, creating drier conditions that favor kiawe pollen and allow Kilauea-sourced vog to settle over the urban core.
Leeward Kiawe Belt
Kiawe-dominated leeward slopes produce large quantities of wind-borne pollen that settles over Honolulu when trade winds weaken, creating the city's dominant tree pollen trigger.
Year-Round Tropical Humidity
Constant 65-80% humidity sustains dust mite and mold populations indoors year-round, with no winter die-off to provide relief for Honolulu residents.
Kilauea Vog Drift
During Kona wind events, volcanic SO2 and sulfate aerosol from Kilauea drift across the island chain to Honolulu, acting as a potent airway irritant that amplifies allergic responses.
