Jatibonico is situated within the fertile plains of the Sancti Spíritus province in central Cuba, serving as a pivotal hub for the region's agricultural output. The terrain is characterized by its predominantly flat topography, which allows for the expansive cultivation of sugarcane, the town's primary economic driver. This urban-rural gradient is seamless, with the town center closely intertwined with vast plantations and the imposing infrastructure of the local sugar mill. Geographically, Jatibonico lies far from the coast, meaning it does not benefit from the immediate cooling effects of sea breezes that scrub pollutants from coastal cities like Cienfuegos. Instead, the local atmosphere is influenced by the broader Caribbean air masses and the surrounding vegetation. The absence of significant topographic barriers means that air pollutants, particularly particulate matter from agricultural activities, can linger or drift across the plains depending on wind velocity. The proximity to the Zaza River basin provides some moisture, but the overall landscape remains dominated by the seasonal cycle of the sugar industry. The urban character is modest, with low-rise construction that does not significantly obstruct airflow, yet the concentration of industrial activity at the mill creates a localized pollution belt. Consequently, the city's air quality is inextricably linked to its land use, where the intersection of industrial processing and open-field farming dictates the chemical composition of the air, making the town's air highly sensitive to biomass burning emissions.

In Jatibonico, air quality is dictated by a binary tropical cycle of wet and dry seasons, overlaid with the critical period of the sugarcane harvest, known as the zafra. During the dry season, stretching from November to April, the air often becomes stagnant. The prevailing northeast trade winds typically help disperse pollutants, but during periods of low wind speed, particulate matter from road dust and diesel exhaust accumulates. The most challenging period for air quality occurs during the zafra, often coinciding with the late winter and spring. The practice of burning sugarcane fields before harvest releases massive quantities of smoke and fine particulate matter into the atmosphere, leading to visible haze and diminished visibility. Conversely, the wet season, from May to October, provides a natural cleansing mechanism. Frequent heavy rainfall and tropical storms effectively wash aerosols and pollutants from the sky, resulting in the cleanest air of the year. However, high humidity during these months can exacerbate the feeling of air heaviness for some. Sensitive groups, including children and those with chronic respiratory conditions, should limit outdoor exertion during the peak zafra months, particularly on windless days when smoke settles. To maintain health, residents are encouraged to stay indoors during active burning windows. The transition months of May and November generally offer the most balanced atmospheric conditions, making them ideal for outdoor activities before the onset of extreme humidity or the heavy harvest-related smog patterns.
