Miami Gardens, Florida, occupies a unique position within the Miami metropolitan area, situated inland from the Atlantic coastline. Its coordinates (25.9433, -80.2426) place it within a low-lying, relatively flat terrain characteristic of the coastal plains of South Florida. The city’s elevation averages only a few feet above sea level, making it particularly vulnerable to the effects of sea-level rise and storm surges. Surrounding Miami Gardens is a mosaic of urban development, interspersed with remnant Everglades ecosystems and agricultural lands to the west. This proximity to both urban and natural environments significantly influences its air quality. The urban-rural gradient is relatively sharp, with denser development concentrated around major thoroughfares like the Florida Turnpike and NW 27th Avenue. The Everglades to the west, while acting as a natural filter, can also contribute to localized humidity and stagnant air conditions. The city’s location within the humid subtropical climate zone means frequent rainfall, but also periods of prolonged dryness. Industrial activity is concentrated further south towards Miami and Fort Lauderdale, but regional transport emissions impact Miami Gardens. The porous limestone bedrock underlying the area limits natural filtration of pollutants, impacting groundwater and potentially contributing to airborne particulate matter.

Miami Gardens experiences a distinct wet and dry season, rather than traditional four seasons, profoundly impacting air quality. The dry season, roughly November through April, sees lower humidity and more stable atmospheric conditions. This can lead to temperature inversions, trapping pollutants near the ground, particularly from vehicle emissions along major roadways. January and February often experience the clearest air, favoured for outdoor activities. However, increased tourism during this period elevates traffic volume, potentially offsetting gains. The wet season, May through October, brings frequent afternoon thunderstorms and increased rainfall, effectively scouring the atmosphere and improving air quality. While rainfall cleanses the air, the high humidity can also promote the formation of mold and mildew, impacting indoor air quality. August and September, peak hurricane season, can bring prolonged periods of stagnant air before, during, and after storms. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit strenuous outdoor activity during periods of high pollen counts in spring and early summer, and monitor local advisories during hurricane threats. The prevailing easterly trade winds generally help disperse pollutants offshore, but can shift during storm events.
