Health guidance
What Does Beijing’s AQI Mean?
General US EPA band education — not a personal medical diagnosis. Prefer official local advisories for decisions.
Good AQI 0–50 Current band
Air quality is considered satisfactory, and air pollution poses little or no risk for most people.
Sensitive groups: No extra precautions are typically needed for outdoor activity under the US EPA “Good” band. Local conditions can still vary.
Moderate AQI 51–100
Air quality is acceptable; there may be a minor risk for a very small number of people who are unusually sensitive to air pollution.
Sensitive groups: Unusually sensitive people may notice mild symptoms on prolonged outdoor exposure. Most people do not need activity changes.
Unhealthy for Sensitive Groups AQI 101–150
Members of sensitive groups may experience health effects; the general public is less likely to be affected.
Sensitive groups: Children, older adults, and people with asthma, COPD, or heart disease should consider reducing prolonged or heavy outdoor exertion.
Unhealthy AQI 151–200
Everyone may begin to experience health effects; sensitive groups may experience more serious effects.
Sensitive groups: Sensitive groups should avoid outdoor activity when possible. Everyone may begin to feel effects — prefer indoor air when you can.
Very Unhealthy AQI 201–300
Health alert: everyone may experience more serious health effects.
Sensitive groups: Health alert: limit outdoor exposure for everyone. Sensitive groups should stay indoors and follow official local guidance.
Hazardous AQI 301–500
Health warning of emergency conditions: the entire population is more likely to be affected.
Sensitive groups: Emergency conditions are more likely. Avoid outdoor activity and follow official local emergency and health sources.
The latest normalized US EPA AQI for Beijing is 3 (Good). The dominant pollutant driving this AQI calculation is PM25. Reported particulate matter: PM2.5 0.6. Observation time (UTC): 2026-10-23 07:00:00. Last retrieved (UTC): 2026-10-23 07:15:56 · freshness: fresh.
Air quality is generally considered satisfactory for most people under the US EPA AQI scale. Conditions can still vary by neighborhood and time of day.
This page uses monitoring-station data associated with OpenAQ location “DRC”. It is not a guarantee of city-wide uniformity.
Official monitoring context
About Air Quality in Beijing
Beijing air quality on ExploreCalcTools is shown as US EPA AQI calculated from OpenAQ pollutant concentrations (PM2.5, PM10, O₃, NO₂, SO₂, CO when reported). Readings reflect the nearest mapped OpenAQ location for this city — neighborhood conditions can differ. 24-hour and 7-day outlooks use the Open-Meteo Air Quality API (CAMS model) and are labeled separately from station measurements. Prefer your local environmental protection agency for official health advisories.
Common questions
FAQ
What is the AQI in Beijing today?
Beijing’s latest normalized US EPA AQI is 3 (Good), observation time (UTC) 2026-10-23 07:00:00.
What AQI scale does ExploreCalcTools use for Beijing (China)?
We report US EPA AQI calculated from OpenAQ pollutant concentrations — not a provider-native AQI field and not a medical diagnosis.
Where do the measurements come from?
Concentrations come from OpenAQ, currently associated with location “DRC”. ExploreCalcTools converts those concentrations to US EPA AQI.
How often is this page updated?
This page refreshes from OpenAQ on a scheduled sync. The last retrieval (UTC) was 2026-10-23 07:15:56 (freshness: fresh). Observation time may differ from retrieval time.
Do you publish AQI forecasts?
Yes — a 24-hour hourly outlook and a 7-day daily outlook from Open-Meteo (CAMS), shown separately from OpenAQ station measurements. These are model estimates, not official government advisories, and missing values are never invented.
