Dhaka’s Morning Haze Signals Another Day of Unhealthy Air as Capital Climbs Global Pollution Charts

On any ordinary Monday morning in Dhaka, the capital does not simply wake up. It emerges slowly from a soft, persistent haze that has settled overnight and shows little intention of lifting. By the time the first office buses and private cars begin their crawl toward Motijheel, Gulshan and the industrial edges of the city, monitoring stations are already registering numbers that place Dhaka once again among the handful of major cities with the worst air quality on the planet. On 26 October 2026 the readings hovered in the high 160s on the Air Quality Index, a range classified as unhealthy for the general population.

These figures are no longer treated as isolated spikes. They have become part of the seasonal rhythm of the dry months. Fine particulate matter, especially PM2.5, remains the dominant pollutant. It is produced by the dense mix of diesel and petrol vehicles that share the same congested corridors, by the brick kilns that still operate on the city's periphery, by construction dust from endless road and building projects, and by the open burning of waste in neighbourhoods where collection systems remain incomplete. When wind speeds drop and rainfall is absent, the particles stay suspended. The result is a visible blanket that softens the outlines of high-rises and leaves a faint metallic taste in the air.

For the city's residents the consequences are immediate and personal. Children walking to school pull scarves or masks higher. Outdoor workers—rickshaw pullers, street vendors, construction labourers—spend long hours breathing the same air with little protection. Clinics and outpatient departments report a steady increase in cases of aggravated asthma, persistent coughs and eye irritation. Doctors note that the burden falls most heavily on the elderly, on those with pre-existing heart or lung conditions, and on low-income households that cannot afford air purifiers or sealed living spaces. Over years of repeated exposure, the cumulative effect raises the risk of more serious chronic disease, though precise long-term data for Dhaka remains limited.

City and national authorities have responded with a familiar set of short-term measures. Water tankers spray major roads to suppress dust. Public advisories urge people to reduce outdoor exercise and keep windows closed. Occasional restrictions are placed on certain construction activities or older vehicles. These steps can produce modest, temporary improvements, yet they rarely alter the underlying sources. Enforcement of emission standards for vehicles remains uneven. Many brick kilns continue to use traditional technology. Solid-waste management still leaves large volumes of material available for burning. Expansion of reliable public transport and systematic greening of the city proceed more slowly than the growth of private vehicles and construction activity.

Experts who study urban air pollution in South Asia point out that Dhaka's problem is shared, to varying degrees, with other large cities in the region, yet the density of population and the combination of sources make the capital particularly vulnerable. Solutions that have worked elsewhere—stricter vehicle inspection regimes, financial incentives for cleaner brick production, expansion of mass transit, and better coordination between city corporations and central agencies—are well known. Implementation, however, requires sustained political attention and resources that are often diverted to more visible infrastructure projects.

As the dry season deepens, the pattern is expected to continue. Rankings will fluctuate from day to day depending on wind, humidity and local activity, but the broader picture remains consistent: for millions of people who live and work in Dhaka, clean air is not yet a reliable daily condition. Until the sources of pollution are addressed at scale, the grey mornings and the advice to stay indoors will remain a regular feature of life in the capital.
