Key West Lighthouse's air quality benefits from the Key West island's exceptional Atlantic Ocean and Gulf of Mexico dual-coastal position, with consistent trade winds providing outstanding maritime ventilation. Vehicle traffic on Whitehead Street contributes modest local sources, while the extraordinary dual-ocean trade wind exposure generally maintains the Key West Lighthouse among Florida's most reliably ventilated historic maritime landmarks throughout most of the year.
