Divo, situated in southwestern Ivory Coast's Gôh-Djiboua region, occupies a strategic position within the country's agricultural heartland. The city lies at approximately 5.8372°N, -5.3572°W, with an elevation of around 150-200 meters above sea level, placing it on the transitional zone between the coastal plains and the interior plateaus. This location within the forest-savanna mosaic creates a distinct urban-rural gradient where Divo serves as a commercial hub surrounded by extensive cocoa, coffee, and palm oil plantations. The city's urban character reflects its role as a regional market center, with moderate density development that blends administrative functions with agricultural processing activities. Proximity to the Bandama River system, approximately 30 kilometers east, provides some hydrological influence, though the city itself lacks major water bodies within its immediate boundaries. The surrounding terrain features gentle undulating hills covered by secondary forests and cultivated lands, creating a landscape where agricultural burning and transportation emissions from rural-to-urban movement significantly impact air quality. Divo's position along major transport corridors connecting Abidjan to the interior ensures constant vehicular traffic, while its location away from coastal breezes allows pollutants to accumulate more readily than in coastal cities. The city's geography as an inland agricultural center means air quality is particularly affected by seasonal burning practices and dust from unpaved rural roads during dry periods.

Divo experiences two main seasons that dramatically influence air quality patterns throughout the year. During the long dry season from November to March, northeasterly Harmattan winds transport Saharan dust across West Africa, creating hazy conditions that reduce visibility and increase particulate matter concentrations. December through February typically represents the peak pollution period when agricultural burning coincides with Harmattan dust, creating a double burden of pollutants. Sensitive groups including children, elderly residents, and those with respiratory conditions should limit outdoor activities during morning hours when temperature inversions trap pollutants near the ground. The rainy season from April to October brings relief through regular precipitation that washes pollutants from the atmosphere, with June through August offering the cleanest air for outdoor activities. However, the transition months of April-May and October-November can see increased pollution from agricultural burning as farmers prepare fields between seasons. Meteorological factors like reduced wind speeds during the rainy season's peak can occasionally allow local emissions to accumulate, particularly from transportation and residential cooking fuels. The absence of significant temperature inversions during the rainy season generally prevents severe pollution episodes, though humidity can make existing pollutants feel more oppressive. For optimal air quality, visitors should plan outdoor activities for the mid-rainy season months when rainfall is consistent but not excessive, avoiding the Harmattan-affected dry months when particulate concentrations are highest.
