Seattle's Chihuly Garden and Glass air quality benefits from the Seattle Center's position with Puget Sound maritime airflows providing reliable ventilation. Vehicle traffic on the surrounding corridors contributes modest local sources, while the glasshouse garden setting and the Centre's open campus generally maintain moderate to good conditions and summer wildfire smoke is the primary seasonal concern for this extraordinary botanical glass art environment throughout most of the year.
