Cabaret, situated in the Ouest department of Haiti at coordinates 18.7358, -72.4193, is a municipality characterized by a complex interplay of coastal plains and hilly terrain. The city’s location, approximately 60km north of Port-au-Prince, places it within a region heavily influenced by the Caribbean Sea. The surrounding landscape is a mix of agricultural land – primarily smallholder farming of crops like mangoes, coffee, and corn – and increasingly, informal settlements expanding outwards from the urban core. Elevation varies considerably, rising from near sea level along the coast to several hundred meters in the interior hills. This topographic variation significantly impacts air circulation patterns, creating localized pockets where pollutants can accumulate. The proximity to the coast introduces sea breezes, which can both disperse and transport pollutants. However, the lack of robust industrial zoning means that emissions from small-scale industries, charcoal production (a major energy source), and vehicle traffic are dispersed throughout the urban area. The urban-rural gradient is relatively sharp, with a rapid transition from densely populated areas to agricultural lands, influencing the types and concentrations of pollutants present. Deforestation in the surrounding hills contributes to soil erosion and dust, further impacting air quality. The city’s position within a tropical climate also means high humidity and potential for temperature inversions, trapping pollutants near the ground.

Cabaret experiences a distinct wet and dry season, heavily influencing its air quality. The dry season, typically from December to April, sees a peak in particulate matter pollution. Reduced rainfall means less atmospheric cleansing, and increased reliance on charcoal for cooking and heating exacerbates the problem. Dust from agricultural activities and unpaved roads also contributes significantly. January and February are generally the months with the poorest air quality. The onset of the wet season in May brings a noticeable improvement, as rainfall washes away pollutants. However, increased humidity can also promote the formation of mold and mildew, potentially triggering respiratory issues. June through November sees relatively cleaner air, though localized pollution from traffic and small industries persists. August and September, coinciding with the peak of the rainy season, are generally the most favourable months for outdoor activity. Temperature inversions, common during the calmer periods of both seasons, can trap pollutants at ground level, particularly in the valleys. Sensitive groups – children, the elderly, and those with pre-existing respiratory conditions – should limit strenuous outdoor activity during dry season mornings and evenings, and be mindful of potential mold exposure during the wet season. Monitoring local conditions is crucial, as weather patterns can shift rapidly.
