South Daytona, Florida, occupies a coastal plain environment within Volusia County, a region characterized by relatively flat terrain and a subtropical climate. Situated just south of Daytona Beach, it’s intrinsically linked to the Atlantic Ocean, a defining feature influencing both its geography and air quality. The city’s location, at approximately 29.1657° N, 81.0055° W, places it within the broader Central Florida metropolitan area, experiencing the urban sprawl and associated pressures of a growing region. The surrounding landscape is a mosaic of residential areas, interspersed with pockets of commercial development and, further inland, agricultural zones primarily focused on citrus and vegetable cultivation. This proximity to agricultural land introduces potential sources of volatile organic compounds (VOCs) and particulate matter, particularly during harvesting and processing seasons. The urban–rural gradient is relatively gradual, with suburban development extending outwards from the coastal areas. Elevation is minimal, rarely exceeding 20 feet above sea level, which can exacerbate the effects of sea breezes and coastal fog, trapping pollutants close to the ground. The prevailing winds generally blow onshore from the Atlantic, carrying marine aerosols and potentially pollutants from upwind sources. The presence of the Halifax River, a major waterway flowing through the area, also influences local weather patterns and can contribute to humidity, impacting the dispersion of airborne contaminants. The relatively low elevation and coastal proximity make South Daytona susceptible to sea-level rise and associated impacts on air quality, including increased saltwater intrusion and potential release of contaminants from coastal wetlands.

South Daytona’s air quality follows a distinct seasonal pattern dictated by its subtropical climate. The wet season, typically spanning from May through October, brings frequent afternoon thunderstorms and high humidity. While rainfall can help cleanse the air by removing particulate matter, the increased humidity can trap pollutants, particularly ozone, which forms readily in warm, sunny conditions. The summer months (June-August) often see elevated ozone levels due to intense solar radiation and stagnant air masses. Conversely, the dry season (November-April) generally offers improved air quality. Cooler temperatures and more frequent wind events promote better dispersion of pollutants. However, occasional temperature inversions, where a layer of warm air sits above cooler air near the ground, can trap pollutants, leading to localized air quality concerns. Fog, common during the cooler months, can also reduce visibility and concentrate pollutants near the surface. Spring (March-April) can be a transitional period, with increasing temperatures and sunshine potentially leading to ozone formation. Fall (September-October) is often characterized by hurricane season, which can temporarily improve air quality through strong winds and rainfall, but also introduce dust and debris from storm damage. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should limit prolonged outdoor activity during peak ozone periods in the summer and be mindful of potential fog-related air quality issues during the winter months. Agricultural burning, though regulated, can also contribute to localized air pollution events, particularly during the dry season.
