Anomabu, a coastal town in the Central Region of Ghana, is situated at coordinates 5.1749° N, -1.1214° W, and home to a population of approximately 14,389. Its geography is fundamentally shaped by its location on the Gulf of Guinea, characterized by a low-lying, sandy coastline. The terrain is generally flat, gradually rising inland towards undulating hills and agricultural lands. This proximity to the ocean exerts a significant influence on local weather patterns and, consequently, air quality. Anomabu’s urban character is that of a traditional fishing town, increasingly experiencing growth related to tourism and small-scale commerce. The surrounding landscape is dominated by coconut plantations, fishing villages, and increasingly, residential development. While not a major industrial hub, the presence of artisanal fishing activities, wood processing for canoes, and local markets contribute to particulate matter emissions. The urban-rural gradient is relatively sharp, transitioning quickly from densely populated coastal areas to more sparsely populated agricultural zones inland. The prevailing winds, typically from the southwest, carry maritime air inland, but can also transport pollutants from regional sources. The lack of significant elevation limits atmospheric dispersion, potentially trapping pollutants near ground level, especially during calm conditions. This coastal setting makes Anomabu particularly vulnerable to the impacts of long-range transport of pollutants and sea breezes affecting pollutant concentration.

Anomabu experiences a tropical climate with distinct wet and dry seasons, profoundly impacting air quality. The dry season, typically from November to March, sees a build-up of dust and particulate matter. Harmattan winds, originating from the Sahara Desert, bring significant amounts of coarse dust, reducing visibility and exacerbating respiratory issues. This is often the period of poorest air quality. The transition period in April and May brings increased humidity and sporadic rainfall, offering temporary relief. The wet season, spanning June to October, generally improves air quality due to rainfall scavenging pollutants from the atmosphere. However, increased humidity can also promote the formation of mold and mildew, impacting indoor air quality. Heavy rainfall can also lead to localized flooding, stirring up sediment and contributing to particulate matter. Temperature inversions, though less frequent than in temperate climates, can occur during the calmer periods of the dry season, trapping pollutants near the surface. Sensitive groups – children, the elderly, and those with pre-existing respiratory conditions – should limit strenuous outdoor activity during the peak of the Harmattan (December-February) and periods of high humidity. Monitoring local weather patterns and avoiding activities near busy roads or wood-burning areas is advisable year-round.
