Khulayş's air quality reflects the flat Saudi Arabian Makkah al Mukarramah region's Hejaz plain position, with vehicle traffic on surrounding roads and the agricultural, government, and residential character contributing local sources. Windblown Hejaz Desert dust generates elevated PM10 during dust events, while the flat Arabian terrain allows reasonable dispersal and Khulays generally maintains moderate to elevated central Saudi Arabian Hejaz plain readings throughout most of the year.
