Air quality in Jakarta right now
Right now the modelled US Air Quality Index for Jakarta, Indonesia is 171, which falls in the "Unhealthy" band (up to 200). Everyone should reduce prolonged or heavy exertion outdoors; sensitive groups should avoid it and keep windows closed.
The index is driven mainly by PM2.5, whose own sub-index is 171. Fine and coarse particles come from traffic, heating, industry, dust and smoke; they build up on calm nights and clear when wind or rain arrives.
PM2.5 is 65 µg/m³, 4.3 times the WHO 24-hour guideline of 15 µg/m³; PM10 is 67 µg/m³ against a guideline of 45; ozone is 89 µg/m³ (below the WHO 8-hour level of 100); nitrogen dioxide is 57 µg/m³ (above the 24-hour guideline of 25).
Also this hour: UV index 4.2, sulphur dioxide at 67 µg/m³, carbon monoxide 1587 µg/m³.

Every third hour of the CAMS forecast via Open-Meteo. US AQI uses rolling averages (24 h for particles, 8 h for ozone), so it moves more slowly than the hourly concentrations.
Best time to be outside in Jakarta today
Between 6 am and 9 pm local time, the cleanest air today is forecast around 9:00 am (AQI 171, Unhealthy) and the worst around 4:00 pm (AQI 176). The difference across the day is small, so timing matters little.

Model vs measured
We found no measured PM2.5 sensor cell within 25 km of Jakarta, so the numbers on this page are model estimates. Models capture regional pollution well but can miss very local sources such as a busy road or a nearby fire.
Wildfire smoke
PM2.5 is forecast to reach 170 µg/m³ in the next 24 hours while NASA satellites detected 6 fire hotspots within 300 km in the last day (nearest about 30 km away). Smoke is a likely contributor: keep windows closed, run an air purifier or HVAC filter, and check the fire map before heading out.
Advice for sensitive groups
At 171, children, older adults, pregnant people and anyone with asthma, COPD or heart disease should limit time outdoors, especially strenuous activity. A well-fitted N95/FFP2 mask cuts particle exposure; it does not filter ozone.
What the US AQI numbers mean
| US AQI | Category | What it means |
|---|---|---|
| 0-50 | Good | Air quality is satisfactory and poses little or no risk; a good time for outdoor activity. |
| 51-100 | Moderate | Acceptable for most people. Unusually sensitive people should consider shortening long or heavy exertion outdoors. |
| 101-150 | Unhealthy for Sensitive Groups | People with heart or lung disease, older adults, children and teens should cut back on prolonged or heavy exertion outdoors. |
| 151-200 | Unhealthy | Everyone should reduce prolonged or heavy exertion outdoors; sensitive groups should avoid it and keep windows closed. |
| 201-300 | Very Unhealthy | Health alert: everyone should avoid prolonged or heavy exertion outdoors, and sensitive groups should stay indoors. |
| 301-500 | Hazardous | Emergency conditions: everyone should avoid all outdoor physical activity and stay indoors with filtered air if possible. The scale tops out at 500; heavier dust or smoke is shown as 500. |
