Sharm el-Sheikh, nestled on the southern tip of the Sinai Peninsula in Egypt, occupies a unique and geographically sensitive position. The city’s urban fabric is intrinsically linked to its coastal location on the Straits of Tiran, a narrow waterway separating Egypt from Saudi Arabia. This strategic location, combined with the surrounding landscape of arid desert and rugged mountains, significantly influences its air quality. The terrain is predominantly characterized by low-lying coastal plains gradually rising to the higher elevations of the Sinai Mountains to the west. Elevation within the city itself is minimal, rarely exceeding 50 meters above sea level, which can exacerbate the trapping of pollutants under certain meteorological conditions. The surrounding landscape is largely barren desert, with limited agricultural activity concentrated in oases further inland. This minimizes diffuse agricultural pollution, but the desert environment contributes to dust storms, a recurring factor in air quality degradation. The urban–rural gradient transitions rapidly from the built-up areas of Sharm el-Sheikh to the expansive desert, with small Bedouin settlements scattered throughout the region. While there are no major industrial belts directly adjacent to the city, the port facilities and tourism-related infrastructure contribute to localized emissions. The proximity to the Red Sea moderates temperatures, but also introduces the potential for sea salt aerosols, which can impact respiratory health and interact with other pollutants. The prevailing winds, generally from the northeast, play a crucial role in dispersing or concentrating pollutants, depending on their strength and direction.

Sharm el-Sheikh’s air quality exhibits a distinct seasonal pattern dictated by its arid climate and prevailing meteorological conditions. The warmest months, June through August, typically experience the poorest air quality due to intense solar radiation and stagnant air masses. High temperatures suppress convective mixing, leading to temperature inversions where a layer of warm air traps cooler air and pollutants near the ground. This phenomenon is frequently accompanied by periods of low wind speed, further hindering pollutant dispersal. Dust storms, originating from the central and eastern deserts, are also more frequent during these months, significantly increasing particulate matter concentrations. Conversely, the cooler months (November to February) generally offer improved air quality. Stronger northerly winds prevail, effectively ventilating the city and dispersing pollutants. Fog, while infrequent, can occasionally form during these months, temporarily reducing visibility and trapping pollutants in localized areas. The transitional months of March-May and September-October see a gradual shift in wind patterns and temperature, resulting in fluctuating air quality. During these periods, the risk of dust storms remains, but is generally less intense than in the summer. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the summer months, limiting outdoor activities during peak heat and dust storm events. Maintaining indoor air quality through air filtration and ventilation is also recommended. The dry climate generally reduces humidity-related respiratory issues, but the prevalence of dust necessitates the use of masks during dust storm episodes.
