Guwahati's air today: where the smoke is coming from
Guwahati's smoke report
The air over Guwahati is almost still right now (under 3 km/h, 30 October, 08:15 IST), so smoke from the city's own sources and from nearby fires can build up instead of blowing away. 20 fires were seen within 250 km in the 24 hours to 30 October, 04:18 IST.
Ranks among the cities with pages here that have any of each: #1 has the most.
Map of the fires around the city, last 24 hours
Each dot is one fire a NASA satellite saw. The wind is calm, so there is no upwind side: smoke from fires on every side can drift in and settle over the city. Red dots are likely crop burning, brown dots other fires. Tap a dot for the village and the time.

What satellites see around Guwahati
What satellites and surveys see around the city. Each is a different measure, so they can't be added up into shares of the air.
Fires around Guwahati in the last 30 days
The busiest of the last 29 days was 26 October, with 43 fire spots within 250 km, 3 of them within 50 km.
within 250 km within 50 km
A fire spot is one fire seen on a day, however many satellites saw it (Pakistan-time days). The archive runs every day from 1 October 2026; before that it holds only the October-November seasons.
NO₂ pollution in Guwahati: traffic, industry and power plants
Over the last 14 days the air over Guwahati held 1.52 times the region's usual level of nitrogen dioxide (NO₂), #38 of 58 cities.
The strongest NO₂ peak within 35 km was 1.7 times the usual level, in the city itself, the pattern of a city's traffic.
From Sentinel-5P's TROPOMI instrument via NASA's GIBS tiles, which publish NO₂ as colour bands: a level here is good to about one band. NO₂ in big cities comes mostly from vehicle engines; peaks are named after what is nearby, which suggests a source but doesn't measure one. NO₂ window 15 October to 28 October 2026.
Landfills
Satellites and aircraft have measured methane rising from Adabari, 6 km from the centre, 5 times, about 250 kg an hour. That puts it #43 of the 58 measured landfills in Pakistan and India.

Power plants and industry
No fossil-fuel power plant is mapped within 50 km of Guwahati, but 67 industrial areas are.

Fires around Guwahati this season compared with past years
Fire spots within 250 km of Guwahati from 1 October to 29 October, each year. These count Suomi NPP alone, so every year is measured by the same instrument and the years compare fairly (the 30-day chart above counts all five satellites, three VIIRS and two MODIS, so its numbers are higher).

Guwahati against the other cities
Each strip holds the cities with pages here that have any of it, the most on the left; the red mark is Guwahati. They are different measures, so a high rank on one isn't a larger share of the air than a high rank on another.

Fires up to 30 October, 04:18 IST. This page updates every 15 minutes. Upwind is a guide, not proof: smoke can travel further than 250 km, the wind turns during the day, and satellites can't see fires under cloud. A fire spot is one fire, about 375 m across, however many satellites saw it. Fires: NASA FIRMS (VIIRS and MODIS). Wind: Open-Meteo's weather model. Air: Copernicus CAMS model estimates, which read low in winter.
