Niagara Falls's air quality is shaped largely by lake-effect winds off Lake Erie and Ontario; mist from the falls adds humidity but rarely affects particulate levels. These factors combine to give Niagara Falls a fairly typical seasonal air quality pattern for this part of the country. Visitors and residents alike tend to notice the clearest air outside the warmest summer weeks.
