Gqeberha, formerly known as Port Elizabeth, occupies a distinctive coastal position on the eastern shores of South Africa's Eastern Cape province, where the Indian Ocean meets the Algoa Bay. This port city sprawls across undulating terrain that rises from sea level to approximately 60 meters in its urban core, with surrounding hills reaching up to 200 meters, creating a natural amphitheatre that can trap pollutants under certain conditions. The city's geography is characterised by its location between the Swartkops River estuary to the north and the Baakens River valley to the south, with industrial zones concentrated along these waterways and in the northern suburbs near the port facilities. Gqeberha serves as the economic hub of the Nelson Mandela Bay metropolitan region, with urban development extending inland toward the semi-arid Karoo region, creating a pronounced urban-rural gradient. The city's air quality is directly influenced by its coastal setting, with prevailing southeasterly winds known as the 'Cape Doctor' typically dispersing pollutants seaward, though these can be disrupted by topographic features. Industrial activities around the port, including automotive manufacturing, chemical plants, and the Coega Industrial Development Zone, represent significant emission sources, while the city's expanding urban footprint contributes to vehicular pollution and occasional biomass burning from informal settlements. The surrounding landscape of coastal dunes, river valleys, and adjacent agricultural lands creates complex air circulation patterns that occasionally lead to pollutant accumulation in residential areas, particularly during periods of atmospheric stability.

Gqeberha experiences distinct seasonal variations in air quality driven by its temperate coastal climate and changing meteorological patterns. During summer (December to February), prevailing southeasterly winds provide excellent ventilation, dispersing pollutants effectively and creating generally favourable air quality conditions ideal for outdoor activities. Autumn (March to May) brings transitional weather with decreasing wind speeds and occasional temperature inversions, particularly in the river valleys, leading to gradual pollutant accumulation from industrial and vehicular sources. Winter (June to August) represents the most challenging period for air quality, with frequent high-pressure systems creating stable atmospheric conditions that trap pollutants close to the ground, exacerbated by increased domestic fuel burning for heating in informal settlements. Sensitive groups including those with respiratory conditions should limit prolonged outdoor exposure during winter mornings when inversion layers are strongest. Spring (September to November) sees improving conditions as increasing wind activity begins to clear accumulated pollutants, though occasional berg winds from the interior can transport dust and smoke into the urban area. The city experiences its cleanest air typically from late spring through summer, while winter months require greater caution, especially for vulnerable populations who should monitor local air quality reports and consider indoor air filtration during periods of poor ventilation. Seasonal fog, though infrequent, can combine with pollution to reduce visibility and air quality temporarily.
