When Indian metro cities, including Delhi and Mumbai, are struggling with toxic air, there are cities where the Air Quality Index (AQI) is excellent. The air is clean and fresh for breathing because of their natural surroundings, low industrial activity and effective pollution control measures.
1. Shillong, Meghalaya: Known for its high elevation and lush forests, Shillong's natural surroundings contribute to its clean air.
2. Ooty, Tamil Nadu: This hill station's cool climate and green spaces make it an ideal spot for fresh air.
3. Aizawl, Mizoram: Aizawl's location in the northeastern hills and minimal pollution keep its air quality good.
4. Palkalaiperur, Tamil Nadu: This rural setting enjoys clean air, thanks to its distance from major industrial areas.
5. Tirunelveli, Tamil Nadu: Coastal winds help disperse pollutants, maintaining good air quality.

Delhi and Mumbai are struggling with poor air quality, with Delhi's Air Quality Index (AQI) currently standing at 303, falling under the 'very poor' category, while Mumbai's AQI is at 115, classified as 'moderate'.
In Delhi, the air quality is expected to remain 'very poor' until December 8, 2025, with several locations, including Anand Vihar and ITO, reporting thick haze and significantly reduced visibility. The city's pollution levels are attributed to various factors, including vehicular emissions, industrial activities, and construction dust.
Mumbai's air quality, although moderate, is still a concern, with pollutants like PM2.5 and PM10 contributing to the city's pollution. The city's weather forecast indicates clear skies and warm temperatures, which may help disperse pollutants, but the AQI is expected to remain steady. The poor air quality in these cities highlights the need for urgent action to combat pollution and ensure cleaner air for residents.
A new study published in Science has challenged this view, suggesting the genetic contribution might be considerably higher.
Several parts of the national capital woke up to dense fog on Monday morning, with the Air Quality Index (AQI) remaining in the moderate to poor categories according to the Central Pollution Control Board (CPCB) data.
India's fight against toxic air just took a hit. The 2026-27 Budget allocated only Rs 1,091 crore to pollution control - down from Rs 1,300 crore last year.
Several parts of Delhi and the wider National Capital Region (NCR) witnessed light rain during the intervening night of Saturday and Sunday. The India Meteorological Department (IMD) has forecast a drop in the maximum temperature for today.
The air quality in Delhi has shown slight deterioration this January compared to last year, with the average Air Quality Index (AQI) till January 30 standing at 307, compared to 306 during the same period in 2025, according to an analysis
