Air quality in Hisar right now
Right now the modelled US Air Quality Index for Hisar, Haryana, India is 300, which falls in the "Very Unhealthy" band (up to 300). Health alert: everyone should avoid prolonged or heavy exertion outdoors, and sensitive groups should stay indoors.
The index is driven mainly by PM10, whose own sub-index is 300. 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 78 µg/m³, 5.2 times the WHO 24-hour guideline of 15 µg/m³; PM10 is 187 µg/m³ against a guideline of 45; ozone is 36 µg/m³ (below the WHO 8-hour level of 100); nitrogen dioxide is 42 µg/m³ (above the 24-hour guideline of 25).
Also this hour: desert dust at 201 µg/m³, high enough to haze the sky, carbon monoxide 440 µg/m³.

Model vs measured
We found no measured PM2.5 sensor cell within 25 km of Hisar, 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 131 µg/m³ in the next 24 hours while NASA satellites detected 254 fire hotspots within 300 km in the last day (nearest about 6 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 300, 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.
