Portsmouth's Strawbery Banke Museum air quality benefits from the historic Piscataqua River waterfront position, with consistent Atlantic and Great Bay estuary breezes providing reliable maritime ventilation. Vehicle traffic on the surrounding Marcy Street corridor contributes modest local sources, while the historic waterfront position and the river's tidal estuary ventilation generally maintain the museum among Portsmouth's more moderately ventilated historic waterfront sites throughout most of the year.
