AQI by neighbourhood 47 areas
NEA reports haze by region, not by street, so each neighbourhood shows the reading of its nearest NEA region. Local air can differ a little.
What the AQI colours mean
0–50 Good: little or no risk.
51–100 Moderate: acceptable; unusually sensitive people may be affected.
101–150 Unhealthy for sensitive groups: active children and adults, and people with lung disease such as asthma, should limit prolonged outdoor exertion.
151–200 Unhealthy: everyone may start to feel effects; sensitive groups should avoid prolonged outdoor exertion.
201–300 Very unhealthy: health warnings of emergency conditions; sensitive groups avoid outdoor exertion, everyone else limits it.
300+ Hazardous: everyone should avoid outdoor exertion.
Inspired by aqicn.org (World Air Quality Index project). Calculated here from NEA readings on the US EPA scale; PM2.5 uses the 12-hour NowCast. aqicn's own numbers may differ slightly. Tap ↗ to open each region on aqicn.org.
