Berkeley Earth conversion: 22.0 µg/m³ PM2.5 ≈ 1 cigarette/day. This compares population-level mortality risk, not individual clinical outcomes. Acute vs chronic exposure differs significantly.
AQLI methodology: each 10 µg/m³ PM2.5 above WHO baseline (5.0 µg/m³) ≈ 0.98 years of life expectancy lost. Calculated from annual mean PM2.5 (long-term exposure), not annual median.
24-hour pattern from the most recent 7 days of hourly data. Dimmed arcs are unsafe for the selected activity.
This is a short-term trend view (not live minute-by-minute monitoring).
Hourly data is currently unavailable for this city. Use the seasonal calendar and health summary for planning decisions.
How does the air here compare to other health risks — and to peer cities?
Every day of the year, colored by PM2.5 air quality band.
The baseline view is No mask. You can switch to Surgical, KN95, or N95 to see a planning range for mask-adjusted exposure. Smoking-aware mode is optional and off by default.

Jakarta residents lose an estimated 3.6 years of life expectancy on average due to PM2.5 air pollution — compared to living in a city that meets WHO air quality guidelines.
Each bar shows estimated life-years lost due to that risk factor. The orange bar is Jakarta. Gray bars are risk comparisons.

Jakarta's pollution pattern inverts the typical Southeast Asian calendar. Most cities in our dataset are worst in winter and improve during the monsoon. Jakarta is worst in the dry season (July–October) and best in the wet season (December–February)—driven by an exceptional cause: peat fires in Kalimantan and Sumatra.
When Borneo's vast peatlands ignite during dry years, smoke crosses the Java Sea and descends on Jakarta. August median: 55 µg/m³, the worst month, with Unhealthy readings on more than half of days. July, September, and October are similarly elevated. The phenomenon is amplified during El Niño years when the dry season is prolonged and peat fires are more severe.
The wet season monsoon (December–February) clears Jakarta's air. February median drops to 22 µg/m³—the city's best month. January is comparable. These months offer the most feasible conditions for outdoor activity, though even wet season Jakarta exceeds WHO guidelines.
Jakarta's annual median of 42.1 µg/m³ represents 3.6 years of life expectancy lost. Schedule your visit for December through March if outdoor activity or air quality is a concern. Check Kalimantan fire season forecasts: in El Niño years, July–October can be significantly worse than the median suggests.
