Lima Air Quality — Live AQI & Pacific Coast Capital Forecast

Lima's coastal desert setting produces persistent low cloud and inversion layers that limit vertical mixing, allowing traffic and industrial emissions to accumulate near the surface. Fine particles often dominate year-round exposure along busy corridors.

Andean dust and construction activity add to PM peaks, while winter garúa moisture can make pollution feel stagnant without fully washing particles away. Summer sunshine occasionally improves ventilation when onshore winds strengthen.

Hourly AQI checks help Limeños plan outdoor exercise, school routes, and ventilation. Choosing inland routes away from diesel corridors during rush hour measurably lowers inhaled pollution.
