This morning, several major Indonesian cities, including Jakarta, Semarang, and Pontianak, recorded refreshingly healthy air quality levels. According to IQAir’s detailed monitoring at 07:20 AM Western Indonesian Time (WIB), these regions boasted Air Quality Index (AQI) scores of less than 50, placing them firmly in the ‘Good’ category. Such excellent air quality is deemed ideal for supporting various outdoor activities, allowing residents to enjoy their surroundings with peace of mind.
“This is an ideal time to engage in outdoor activities with little or no risk posed by the air inhaled,” stated IQAir, as quoted on Monday, May 25.
Here is a detailed list of Indonesian cities enjoying the best air quality on Monday morning, May 25:
- Pontianak, West Kalimantan, leading with an AQI score of 39, categorized as good.
- Semarang, Central Java, closely following with an AQI score of 44, also within the good category.
- Jakarta, recording an AQI score of 50, which still falls within the healthy range.
- Pekanbaru, Riau, entering the moderate category with an AQI score of 58.
- South Tangerang, also showing moderate air quality with an AQI score of 66.
In stark contrast to these favorable conditions, Surabaya, East Java, registered the poorest air quality across Indonesia this morning. With an alarming AQI score of 151, Surabaya’s air quality was classified as unhealthy, posing potential risks to its residents.
When air quality falls into the ‘Unhealthy’ category, the general public, particularly sensitive groups such as children, the elderly, pregnant individuals, and those with pre-existing heart or lung conditions, are susceptible to adverse health effects. As highlighted by IQAir, “When air quality is categorized as unhealthy, the general public, especially sensitive groups, may begin to experience health effects.”
Consequently, IQAir advises the public to reduce outdoor activities during such periods. The Meteorology, Climatology, and Geophysical Agency (BMKG) has also repeatedly urged communities to wear masks, especially when in areas with high levels of air pollution, as a precautionary measure.

Delhi, India Experiences the World’s Worst Air Quality This Morning
On a global scale, the situation in some major cities reaches even more critical levels, with air quality falling into the ‘Very Unhealthy’ category. Delhi, India, notably stood out with the most severe air pollution this morning. Here is a list of cities with the worst global air quality:
- Delhi, India, topped the list with an AQI score of 223, indicating ‘Very Unhealthy’ air.
- Santiago, Chile, followed with an AQI score of 180, categorized as ‘Unhealthy’.
- Lahore, Pakistan, recorded an AQI score of 171, also falling into the ‘Unhealthy’ bracket.
- Kinshasa, Democratic Republic of Congo, showed an AQI score of 157, signaling ‘Unhealthy’ conditions.
- Dhaka, Bangladesh, reported an AQI score of 156, similarly classified as ‘Unhealthy’.
In stark contrast to these challenging conditions, several other major global cities enjoyed exemplary air quality. Stockholm, Sweden, led this positive trend with an outstanding AQI score of just 6. It was closely followed by Dublin, Ireland, with an AQI of 10, and San Francisco, United States, which reported a healthy AQI of 14.
The Air Quality Index (AQI) serves as a crucial metric, representing the concentration of various air pollutants and thereby indicating the overall quality of the air. This comprehensive index takes into account six primary pollutants: PM2.5 (fine particulate matter), PM10 (coarse particulate matter), carbon monoxide, sulfur dioxide, nitrogen dioxide, and ground-level ozone. The cumulative AQI at any given time is ultimately determined by the pollutant deemed most hazardous, which registers the highest individual AQI score. The AQI scale itself ranges from 0 to 500, segmented into six distinct categories to convey varying levels of health risk.
Understanding these categories is vital for public health. The ‘Good’ category spans AQI scores from 0 to 50, signifying minimal risk. The ‘Moderate’ category includes scores from 51 to 100. Following this, the ‘Unhealthy for Sensitive Groups’ category covers scores between 101 and 150. Meanwhile, the ‘Unhealthy’ category ranges from AQI scores of 151 to 200, indicating a broader risk to the general population. The ‘Very Unhealthy’ category, with scores from 200 to 299, suggests significant health concerns for a larger segment of the exposed population. Finally, the ‘Hazardous’ category, encompassing scores from 300 to 500, denotes grave health risks to the entire human population.
Specifically, air quality categorized as ‘Very Unhealthy’ can be significantly detrimental to the health of exposed populations. Even more critically, air quality in the ‘Hazardous’ category poses severe health risks, potentially causing serious harm to the human population.
Summary
Several major Indonesian cities, including Jakarta, Semarang, and Pontianak, experienced healthy air quality on the morning of May 25, with Air Quality Index (AQI) scores falling within the ‘Good’ range of 50 or below. This improvement allowed residents to safely engage in outdoor activities. In contrast, Surabaya recorded an unhealthy AQI of 151, prompting warnings for vulnerable groups to limit outdoor exposure and follow safety precautions like wearing masks.
Globally, air quality varied significantly, with Delhi, India, reporting the worst conditions categorized as ‘Very Unhealthy’ with an AQI of 223. Conversely, cities such as Stockholm, Dublin, and San Francisco enjoyed excellent air quality. Experts emphasize that the AQI, which tracks six primary pollutants, is a vital metric for public health, with categories ranging from ‘Good’ to ‘Hazardous’ to help inform citizens about potential health risks.
