A dense layer of smog engulfs the Kathmandu Valley in Kathmandu, Nepal, on March 13, 2026. Air pollution intensifies across the bowl-shaped capital, with the Air Quality Index (AQI) fluctuating between 200 and 250, placing the city in the ''very unhealthy'' category and among the world's most polluted cities, according to data from the air quality monitoring platform IQAir's AirVisual. Measurements show fine particulate matter (PM2.5) at 129.9 micrograms per cubic meter--more than 25 times higher than the safe limit recommended by the World Health Organization--while PM10 levels reach 100.3 ug/m3. Nepal's national AQI scale classifies readings above 200 as very unhealthy and levels exceeding 300 as hazardous. The Ministry of Health and Population advises residents to take protective measures, noting that long-term exposure to polluted air can lead to serious health complications including asthma, chronic obstructive pulmonary disease (COPD), heart disease, stroke, and lung cancer. Studies on air pollution also link prolonged exposure to increased risks of diabetes, reduced lung function, and premature death.
