What the numbers say
Overview
Navi Mumbai's AQI moved from 78 in 2016 to 107 in 2024 — a rise of 37.2% over 8 years. The long-run trend is worsening, with a regression slope of 6.4 AQI points per year.
The data story
The worst recorded year in Navi Mumbai was 2022 at AQI 139, while the best was 2016 at AQI 78. The city has posted 17.099999999999998% of all measured days above AQI 200 (the Poor threshold), and its worst recorded single day hit 477 on 14 Apr 2019.
Why this pattern
A worsening trend in Navi Mumbai typically reflects rapid urbanisation, vehicle fleet growth outpacing Bharat Stage VI emission benefits, expanding industrial activity, and in some cases new construction dust. The data points the finger at what policy needs to target next: year-round baseline emissions, not just the winter peak.
What to do with this
For planners and residents, the trend matters as much as today's number. A worsening city needs aggressive source control and personal protection investments like indoor purifiers. An improving city rewards continued policy pressure but still requires caution during peak months. Use the live AQI page for day-to-day decisions and this chart for multi-year context. Year-over-year change of more than 10% in either direction is typically real signal, not noise.
