Mumbai’s monsoon is fading, and air pollution is beginning to return.
On 3 October 2026, Mumbai’s overall Air Quality Index (AQI) reached 111, crossing 100 for the first time this post-monsoon season. Of the 20 active monitoring stations, 10 recorded air quality in the “moderate” category, with Worli reaching an AQI of 178 and Colaba 143.
This is an important reminder that as the weather changes, the quality of the air we breathe deserves attention too.
Why Is Mumbai’s Air Quality Getting Worse?
Rain naturally helps wash pollutants and suspended particles out of the atmosphere. As monsoon rainfall reduces, this cleaning effect becomes weaker.
At the same time, vehicle emissions, construction dust and other urban pollution sources continue to add pollutants to the air. Recent reporting has also highlighted rainfall deficit and changing weather conditions as factors that could make Mumbai’s upcoming pollution season more challenging.
What Does Air Pollution Do to Your Respiratory Health?
Poor air quality can irritate the respiratory system. Depending on the pollution level, duration of exposure and individual health, people may experience:
- Coughing or throat irritation
- Eye and nose irritation
- Breathing discomfort
- Wheezing or worsening of existing respiratory symptoms
- Difficulty during strenuous outdoor activity
Children, older adults and people with existing lung or cardiovascular conditions may be more sensitive to polluted air.
PM2.5: The Pollution You May Not See
One important component of air pollution is PM2.5—very small airborne particles measuring 2.5 micrometres or less.
Because these particles are extremely small, they can travel deep into the respiratory system when inhaled. This is why a day that does not necessarily look heavily polluted can still have unhealthy air.
Should You Check AQI Before Going Outside?
Yes—particularly when planning prolonged outdoor exercise or when you are sensitive to air pollution.
India’s AQI system classifies 101–200 as “moderate.” Checking your local AQI can therefore be a simple addition to your daily routine, just like checking the weather.
When pollution levels are elevated, consider reducing strenuous outdoor activity, avoiding unnecessary exposure to heavy traffic and construction dust, and following medical advice if you already have a respiratory condition.
Don’t Ignore Persistent Respiratory Symptoms
An occasional cough does not automatically indicate a serious respiratory problem. However, persistent coughing, wheezing, chest discomfort or difficulty breathing should not simply be blamed on pollution.
If symptoms continue or become worse, seek medical advice so the underlying cause can be properly evaluated.

FAQs
1. Why does Mumbai’s air quality worsen after the monsoon?
Reduced rainfall means fewer pollutants are washed out of the atmosphere, while traffic, construction and other urban emissions continue.
2. What does AQI above 100 mean?
Under India’s AQI categories, 101–200 is classified as moderate air quality. People particularly sensitive to air pollution may need greater caution.
3. Can air pollution affect healthy people?
Yes. Depending on exposure levels and duration, polluted air can cause temporary eye, nose, throat or respiratory irritation even in otherwise healthy individuals.
4. Who needs to be more careful when pollution increases?
Children, older adults and people with existing respiratory or cardiovascular conditions may be more vulnerable to the effects of poor air quality.
5. How can I reduce my exposure to air pollution?
Check local AQI, limit strenuous outdoor activity when pollution is elevated, avoid unnecessary exposure to traffic and construction dust, and follow medical advice if you have an existing respiratory condition.
6. Can Lung Care protect me from air pollution?
No supplement can replace reducing pollution exposure. Aayush Lung Care is intended only to support general respiratory wellness and should not be considered a treatment or protection against pollution-related disease.
