Riyadh Air Quality — Live AQI & Desert Capital Forecast

Riyadh faces intense desert dust events that can dominate PM10 and fine-particle readings within hours. Urban traffic, construction, and energy-sector activity add nitrogen dioxide and particles along major highways year-round.

Dry heat and strong sunshine limit ozone chemistry somewhat compared with humid megacities, but dust resuspension during shamal winds remains the primary health concern. Calm nights rarely trap pollution as severely as in cooler inland basins.

Live AQI alerts help residents decide when to limit outdoor exertion, close windows, and protect sensitive lungs during dust storms. Indoor filtration and timing errands before afternoon wind peaks reduce exposure.
