Al Khubar, situated in the Eastern Province (Ash Sharqīyah) of Saudi Arabia, occupies a strategically important coastal position on the Arabian Gulf. Its coordinates (26.3000, 50.2167) place it within a relatively flat, sandy coastal plain, gradually rising towards the interior plateau. The city’s urban fabric is characterized by a mix of modern high-rise developments and traditional neighborhoods, reflecting its rapid growth fueled by the petroleum industry and associated services. Al Khubar’s proximity to the larger industrial hub of Dammam, forming part of the Dammam–Al Khubar–Qatif metropolitan area, significantly influences its environmental profile. To the west, the landscape transitions into expansive agricultural zones, primarily focused on date palm cultivation and other irrigated crops, which can contribute to localized dust and agricultural emissions. The surrounding terrain is largely arid desert, punctuated by occasional wadis (dry riverbeds) that can become sources of dust storms, particularly during periods of strong winds. The Arabian Gulf to the east provides a moderating influence on temperatures, but also introduces the potential for sea salt aerosol deposition. The urban–rural gradient is relatively sharp, with the city quickly giving way to desert landscapes. Elevation is generally low, rarely exceeding 30 meters above sea level, which can exacerbate air pollution episodes due to limited atmospheric dispersion. The city’s location within a major oil-producing region means it is inherently linked to industrial activity and the associated air quality challenges, compounded by regional weather patterns and the prevalence of dust.

Al Khubar experiences a distinctly hot and dry climate, with air quality patterns heavily influenced by seasonal shifts. The summer months (June-August) are characterized by intense heat, minimal rainfall, and stagnant air conditions. High temperatures suppress atmospheric mixing, leading to temperature inversions that trap pollutants near the ground, often resulting in periods of reduced visibility and elevated particulate matter. Dust storms, originating from the surrounding deserts, are frequent during this period, significantly degrading air quality. The transition months of spring (March-May) and autumn (September-November) offer slightly more favorable conditions, with increased wind speeds aiding in pollutant dispersion, though dust events remain a possibility. Winter (December-February) is the most pleasant time of year, with cooler temperatures and generally improved air quality. However, fog events, particularly in December and January, can temporarily reduce visibility and trap pollutants close to the surface. Meteorological factors such as the Shamal winds, which occasionally sweep across the region, can provide temporary relief by clearing pollutants. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during summer months and periods of dust storms, limiting outdoor activity and utilizing air filtration systems. During the cooler months, while generally better, fog events warrant similar precautions. Maintaining awareness of regional weather forecasts and adhering to public health advisories is crucial for minimizing exposure to potentially harmful air pollutants.
