Westview, Florida, nestled in the southeastern expanse of the state at 25.8825° N, 80.2415° W, occupies a geographically vulnerable position within the Atlantic coastal plain. The city’s terrain is predominantly flat, characteristic of the low-lying landscape of southern Florida, with an average elevation barely exceeding 10 feet above sea level. This flatness significantly influences air quality, limiting vertical mixing and potentially trapping pollutants close to the ground, especially during periods of stagnant air. Westview’s proximity to the Atlantic Ocean is a defining feature, bringing both maritime influences and potential challenges. Sea breezes, while generally dispersing pollutants, can also carry saltwater aerosols, impacting respiratory health. The surrounding landscape is a mosaic of residential areas, interspersed with pockets of agricultural land, primarily focused on citrus and vegetable farming. This agricultural activity introduces potential sources of ammonia and pesticides into the air, though typically localized. Further inland, the urban–rural gradient transitions to more extensive agricultural zones and eventually to the Everglades ecosystem, a vast wetland that acts as a natural filter but can also contribute to methane emissions. The absence of significant topographic barriers means that pollutants originating from larger urban centers to the north, such as Miami, can occasionally drift southward, impacting Westview’s air quality. The region’s subtropical climate, with its high humidity and frequent rainfall, can both cleanse and exacerbate air pollution, depending on meteorological conditions.

Westview’s air quality follows a distinct seasonal pattern dictated by its subtropical climate. The wet season, spanning roughly May through October, brings frequent afternoon thunderstorms and high humidity. While rainfall generally helps to scrub pollutants from the atmosphere, the high humidity can trap particulate matter, particularly during periods of calm winds. The frequent cloud cover also reduces solar radiation, which can hinder the breakdown of ozone. The dry season, from November to April, presents a different set of challenges. Cooler nighttime temperatures during these months can lead to temperature inversions, where a layer of warm air traps cooler air (and pollutants) near the ground. This phenomenon is most pronounced in December and January, potentially leading to elevated concentrations of pollutants. Wind patterns are crucial; prevailing easterly winds from the Atlantic typically provide some dispersion, but periods of stagnant air, often associated with high-pressure systems, can significantly worsen air quality. During the summer months, photochemical smog, driven by intense sunlight and high temperatures, can be a concern, although the frequent rainfall tends to mitigate its severity. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should limit prolonged outdoor activity during periods of stagnant air or temperature inversions, particularly in the early morning hours. The spring and fall months generally offer the most favorable conditions for outdoor recreation, with moderate temperatures and more consistent wind patterns.
