Herẕliyya's air quality benefits from its exceptional Israeli Mediterranean Sea coastal position, with consistent Mediterranean westerlies providing reliable maritime ventilation along the Sharon coastal plain. Vehicle traffic on surrounding roads and the hi-tech Herzliya Pituach technology park and residential corridor contribute local sources, while the outstanding Mediterranean coastal exposure generally maintains Herzliya among Israel's more moderately ventilated major coastal metropolitan environments throughout most of the year.
