Nísia Floresta, nestled in the Rio Grande do Norte state of Brazil, occupies a geographically significant position within the Baixo Oeste region. Located approximately 28 kilometers south of Natal, the state capital and a major coastal hub, the city’s coordinates (-6.0908, -35.2089) place it inland, yet within a relatively short distance of the Atlantic Ocean. The terrain is characterized by a gently undulating landscape, transitioning from coastal plains to slightly elevated areas, with an average elevation of around 20 meters above sea level. This low elevation, combined with proximity to the ocean, influences local weather patterns and contributes to potential coastal breezes. The surrounding landscape is a mosaic of small-scale agriculture, primarily focused on fruit cultivation (particularly mangoes and coconuts) and livestock farming, interspersed with patches of caatinga vegetation – a semi-arid biome typical of northeastern Brazil. The urban–rural gradient is relatively gradual, with agricultural activities extending close to the city limits. While Nísia Floresta itself lacks significant heavy industry, its proximity to Natal means it is indirectly influenced by industrial activity and transportation corridors associated with the larger city. The prevailing winds, often originating from the Atlantic, can carry pollutants from Natal, though the distance and intervening landscape typically dilute their impact. The Potengi River, flowing nearby, also plays a role in local microclimates and potential humidity levels, which can affect the dispersion of airborne particles. The city’s relatively small size and primarily agricultural surroundings generally contribute to a less polluted environment compared to larger, more industrialized urban centers.

Nísia Floresta experiences a tropical climate with a distinct wet and dry season, rather than the four traditional seasons. The dry season, typically spanning from August to December, is characterized by consistently high temperatures and minimal rainfall. During this period, air quality tends to be more stable, with reduced moisture in the atmosphere. However, the lack of rainfall can lead to a build-up of particulate matter, particularly dust from agricultural activities and unpaved roads, especially during periods of strong winds. The wet season, from January to July, brings increased rainfall and higher humidity. This increased moisture generally helps to cleanse the air, washing away particulate matter and reducing dust levels. However, periods of intense rainfall can sometimes lead to localized flooding, which can temporarily release pollutants from inundated areas. The months of March and April often see a transition period with unpredictable weather patterns, potentially leading to stagnant air and localized pollution episodes. Temperature inversions, though less frequent than in colder climates, can occasionally occur during the dry season, trapping pollutants near the ground. Sensitive groups, such as children, the elderly, and individuals with respiratory conditions, should be particularly mindful during the dry season, limiting outdoor activity during periods of high wind and dust. During the wet season, while overall air quality is generally improved, those with allergies should be aware of increased pollen counts and potential mold growth. Maintaining well-ventilated indoor spaces and avoiding prolonged exposure to flooded areas are advisable.
