Chennai Air Quality — Live AQI & Coromandel Coast Forecast

Chennai's air quality reflects expanding traffic, port activity, and industrial belts along the Coromandel Coast. Sea breezes can improve neighbourhoods near the shore while inland districts retain higher PM2.5 during stagnant afternoons.

Summer heat raises ozone and dust resuspension from dry roads, while northeast monsoon rains often scrub particles temporarily. Construction across the metro adds fine dust during long dry spells.

Live AQI helps residents schedule beach runs, commutes, and children's outdoor time when ventilation is strongest. Post-rain mornings frequently offer the best air of the week.
