What this air does to your body

4.6
cigarettes/day equivalent
Breathing today's PM2.5 (101 µg/m³) is roughly like smoking 4.6 cigarettes a day — Berkeley Earth's rule of thumb (22 µg/m³ ≈ 1 cigarette).
−9.4 yr
life-expectancy impact
If this level held all year, it would cut average life expectancy by about 9.4 years versus the WHO guideline (5 µg/m³), per the AQLI method.

About air quality in Byrnihat

This page tracks the Byrnihat Air Quality Index using measurements from 2 Central Pollution Control Board (CPCB) monitoring stations, published through the Government of India's open-data portal. Right now Byrnihat's AQI is 237 (Poor), with PM2.5 the dominant pollutant. The AQI is a single number from 0 to 500 that summarises how polluted the air is and what it means for health, built from pollutants such as fine particulate matter (PM2.5), coarse particulate matter (PM10), nitrogen dioxide, ground-level ozone and sulphur dioxide — the index reflects whichever is worst at the time.

How Byrnihat's air changes through the year

Air quality in Byrnihat changes through the day and across the seasons. Levels are usually worse in the early morning and late evening when cooler, calmer air traps pollutants near the ground, and they tend to rise in the cooler months when inversions are more common; the monsoon typically brings the cleanest air as rain washes particulates away.

What drives air pollution in Byrnihat

Traffic, construction and road dust, industry and the burning of solid fuels are the main local sources, with regional factors and winter weather adding to the load when the air is calm.

Cleaner and worse areas within Byrnihat

Air quality is not uniform across a city. Among Byrnihat's monitoring areas right now, the air is cleanest around 15th Mile-Nongthymmai, Byrnihat -Meghalaya PCB and worst around Central Academy for SFS, Byrnihat - PCBA — a reminder that local traffic, industry and construction can make a real difference over just a few kilometres. The live area-by-area comparison above shows where to go and where to avoid at this moment.

Best time to visit Byrnihat for cleaner air

For the cleanest air, the monsoon and the months just after it are usually best in Byrnihat, while the driest, stillest weeks can be worse. Check the live reading on this page before outdoor exercise or sightseeing, and keep an N95 mask handy for high-pollution days. Nearby cities with comparatively cleaner air right now include Madikeri, Srinagar, Thoothukudi.

Staying safe in Byrnihat's air

When the AQI is in the Good or Satisfactory range, outdoor activity is fine for almost everyone. From Moderate upward, sensitive groups — children, older adults, pregnant people and anyone with asthma or heart disease — should pace themselves outdoors, and once the air turns Poor or worse it is sensible for everyone to limit strenuous outdoor exertion, keep windows closed, run an air purifier indoors and wear a well-fitting mask outside. This is general information rather than medical advice. We only display a number when a recent station reading exists — if you see "data updating", we are waiting on a fresh value rather than showing an estimate.
