Burj al ‘Arab, a coastal city within the Al Iskandarīyah Governorate of Egypt, occupies a unique position along the Mediterranean Sea at approximately 30.9167°N, 29.5333°E. With a relatively small population of around 12,625, it’s characterized by a rapidly urbanizing landscape transitioning from agricultural lands inland. The terrain is generally flat, typical of the Nile Delta, with a very low elevation, making it particularly vulnerable to sea-level rise and associated coastal erosion. Its location directly on the Mediterranean provides a moderating influence on temperatures, but also exposes it to marine aerosols and salt spray, impacting air quality. To the south lies the densely populated and industrialized Al Iskandarīyah city proper, a significant source of pollutants transported by prevailing winds. The surrounding landscape is a mix of intensive agriculture – particularly fruit orchards and vegetable farms – and increasingly, residential and commercial development. The urban-rural gradient is compressed, with agricultural areas quickly giving way to built-up environments. This proximity to both agricultural activity (potential for pesticide drift and biomass burning) and a major urban centre creates a complex air quality profile. The city’s coastal location also means it’s susceptible to long-range transport of pollutants from across the Mediterranean basin.

Air quality in Burj al ‘Arab follows a distinct seasonal pattern heavily influenced by meteorological conditions. The summer months (June-August) often see a slight deterioration due to increased temperatures and stable atmospheric conditions, leading to temperature inversions that trap pollutants near the ground. However, the prevailing sea breeze offers some dispersion. Autumn (September-November) typically brings improved air quality as temperatures cool and winds become more frequent, flushing out accumulated pollutants. This is generally the most favourable period for outdoor activities. Winter (December-February) can experience periods of stagnant air, particularly with the occasional fog formation, leading to localized pollution build-up from domestic heating and vehicle emissions. The spring (March-May) is a transitional period, with increasing agricultural activity – including potential for controlled burns – contributing to particulate matter. Dust storms, originating from the Sahara Desert to the west, are a recurring issue, particularly in spring, significantly impacting visibility and respiratory health. Sensitive groups, including children, the elderly, and those with respiratory conditions, should limit strenuous outdoor activity during dust storm events and periods of stagnant air. Monitoring wind direction is crucial, as pollutants from Al Iskandarīyah are often transported towards Burj al ‘Arab.
