Air quality in Yau Ma Tei estimated
Yau Tsim Mong District, Hong Kong. No ground monitor we can use is in this city, so these numbers are model estimates, not measurements.
≈ 12 µg/m³
Moderate
Estimated PM2.5, 7-day average to 2026-09-30, about 0.8× the WHO 24-hour guideline. 30-day average ≈ 17 µg/m³.
Model estimate from the Copernicus Atmosphere Monitoring Service (CAMS), scaled by 0.51 to match 10 measured cities within 300 km over the last week. Adjusted this way, a single day lands within ×1.5 of what a monitor would read about two times in three: a guide, not a measurement. Not ranked on SmogRank's boards.
