Tabatinga, nestled in the state of São Paulo, Brazil, presents a unique geographic context influencing its air quality. Located at coordinates -21.7169, -48.6878, the city sits within a gently undulating terrain characteristic of the state’s interior. With a population of approximately 14,769, Tabatinga is a relatively small urban center, positioned within a predominantly agricultural landscape. The surrounding region is dominated by sugarcane plantations and cattle ranching, common features of São Paulo’s western interior. The urban-rural gradient is quite sharp, transitioning quickly from small-town density to expansive farmland. While not directly adjacent to major waterways, the city lies within the broader Tietê River basin, and its hydrology is influenced by smaller tributaries. The elevation is moderate, around 580 meters, which contributes to stable atmospheric conditions at times. The lack of significant industrial belts within Tabatinga itself is a positive factor, however, regional agricultural practices – including seasonal burning for land preparation – are a key source of particulate matter. The prevailing winds, generally from the south-southeast, can transport pollutants from more industrialized areas to the east, impacting local air quality. This interplay of agricultural activity, regional winds, and moderate elevation defines Tabatinga’s environmental challenges.

Tabatinga experiences a distinct wet and dry season, rather than traditional four seasons. Air quality in Tabatinga is most compromised during the dry season, typically from May to September. This period sees reduced rainfall, leading to increased dust and particulate matter from agricultural activities, particularly sugarcane harvesting and burning. Lower humidity also means pollutants become more concentrated. Temperature inversions, common during cool, clear nights in the dry season, trap pollutants near the ground, exacerbating the issue. October and November bring the transition to the wet season, with increased rainfall gradually washing away accumulated pollutants and improving air quality. The wet season, from December to April, generally offers the best air quality, as rain effectively clears the atmosphere. However, even during the wet season, localized pollution from vehicle emissions and small-scale burning can occur. Sensitive groups – children, the elderly, and those with respiratory conditions – should be particularly cautious during the dry season, limiting strenuous outdoor activity and monitoring their health. Fog can also form during cooler mornings, potentially trapping pollutants. Avoiding outdoor exertion during peak burning times in the dry season is advisable.
