Global hubs like Doha, Qatar, Dubai, UAE, Kuwait City, Kuwait, Manama, and Bahrain, lie on the coastal area of the Arabian Peninsula and are home to millions of residents and expatriates. These cities regularly rank among the most polluted major cities in the world due to persistently high dust concentrations, even in winter. This makes air quality a year-round public health priority.
While dust storms are usually associated with scorching summer temperatures, winter brings its own air quality health concerns. Winter dust and sand can pose an equally serious threat to human health on the Arabian Peninsula for some surprising reasons.
Contrary to what many expect, cooler winter weather doesn’t bring cleaner air or less air pollution to the Arabian Peninsula.
The winter dust paradox
A combination of meteorological and human factors ensures the persistence of dust through the Arabian Peninsula’s winter months.
Strong seasonal winds, like the northwesterly “shamal,” carry fine particles from the deserts of Iraq, Saudi Arabia, and Iran into Arabian Peninsula communities (1). Although dry, hot shamals are typically associated with the summer, they can occur in winter as well. And while dust storms are less common than in summer, they can still trigger flight cancellations and school closures (2).

In addition to these wind-driven events, other natural and human sources add to the region’s burden. Salt blown in from the sea, rapid-paced construction, and vehicle and petrochemical industrial emissions all contribute to wintertime pollution (3).
As a result, the largest cities on the Arabian Peninsula routinely exceed the WHO guideline for PM2.5 of 5 μg/m3 or less, even in winter. According to the 2024 World Air Quality Report, Bahrain, Iraq, Kuwait, Qatar, and the United Arab Emirates were among the top 25 most polluted cities in 2024, in part due to the consistently poor air quality throughout the year. Another regional nation, Iran, was absent from the report due to a lack of air quality monitoring data.
Unlike in the summer, winter dust can be more insidious. Outside of shamal events, weaker winds and temperature inversions—when a layer of warm air sits above cooler air near the surface—can trap pollutants close to the ground (4). This keeps dust and other pollutants lingering for longer periods.
Where does the dust come from?
The region’s dust has both natural and human-caused origins. Natural sources include the vast deserts of the Arabian Peninsula and Mesopotamia, while human activities—construction, vehicle emissions, and industrial operations—intensify the problem.
Transboundary dust transport poses a significant health challenge on the Arabian Peninsula, with winds carrying particles from as far as North Africa and the Tigris-Euphrates basin. Satellite imagery and dust modeling confirm that dust events are frequent in winter, with major plumes blown across the sea from Iraq, Syria, and Saudi Arabia (5)(6).
For example, on December 11, 2025, high concentrations of dust and sand flowed into the area from the Rubʿ al-Khali on the Arabian Peninsula, while some dust from Iraq, Iran, and Saudi Arabia was carried south into the region (7). Consequently, air quality in Dubai was “moderate” to “unhealthy” several times throughout the day.

Health risks of Arabian Peninsula regional dust
Exposure to dust, especially fine particles like PM2.5, is linked to a range of health issues. These include respiratory diseases such as asthma, chronic obstructive pulmonary disease, as well as cardiovascular problems that can contribute to heart attacks and strokes.
This is because when inhaled, tiny particles can enter the blood stream and eventually reach every organ in the body.
Even prolonged exposure to PM10 – larger particulate matter measuring 10 microns in diameter or less – can lead to serious health complications.
Studies show that dust storms in the region increase hospital admissions for respiratory and cardiovascular conditions (8)(9). Going inside to avoid the dust isn’t always a refuge; without proper ventilation and filtration, dust penetrates homes and workplaces, maintaining high exposure levels.
Protect yourself from dust
There are many ways people in the region can protect themselves from dust.
- Source control: While sandstorms are driven by geography and weather and cannot be prevented, human-made pollution sources can be reduced. Limiting vehicle idling, supporting green urban planning, and advocating for stricter controls on construction and industrial emissions can help lower overall particulate pollution.
- Ventilation: Open windows only when outdoor air quality is good; close windows and set the HVAC to recirculate mode when it’s not.
- Air quality awareness: Download a free air quality app; knowing what’s in the air we breathe empowers people to make choices during poor air quality events.
- Community action: Less than 1% of global ground-based air quality monitoring stations producing data for the 2024 World Air Quality Report were in West Asia. A combination of indoor and outdoor air quality monitors helps comprehensively inform residents about poor air quality conditions, while outdoor air quality monitors raise air quality awareness across communities.
- Air filtration: Use high-performance, medical-grade air purifiers on poor air quality days, especially in bedrooms and living areas.
- Personal protection: Wear a protective KN95/FFP2 mask when it’s necessary to be outdoors on poor air quality days.
The takeaway
Winter dust on the Arabian Peninsula is a persistent, underrecognized threat. While natural factors play a role, human activities and regional policies heavily influence the severity and duration of dust events.
People can protect themselves with smart ventilation practices, high-performance air filtration, and staying informed about daily conditions. Governments and communities can help reduce dust exposure through green-belt development, emissions controls, and expanded air monitoring networks.
