Daytona Beach, Florida, is a coastal city uniquely positioned on a barrier island along the Atlantic Ocean at coordinates 29.1995, -81.0982. Its geography is dominated by low-lying terrain, with an average elevation of only 10 feet above sea level, making it particularly vulnerable to storm surge and sea-level rise. The city’s urban character is a blend of tourism-focused development, residential areas, and some light industrial activity concentrated inland. Regionally, Daytona Beach sits within Volusia County, part of the larger Florida East Coast corridor. The surrounding landscape is a mix of coastal dunes, salt marshes, and the Halifax River, an estuary that runs parallel to the coastline. To the west, the terrain transitions into a more rural landscape of agricultural lands and freshwater wetlands. This proximity to both the ocean and agricultural zones influences air quality; sea breezes can disperse pollutants, but agricultural practices can contribute to particulate matter and ammonia. The urban-rural gradient is relatively sharp, with denser development concentrated along the beach and gradually thinning westward. The constant interaction between land and sea breezes, coupled with the flat topography, affects pollutant dispersion patterns, often leading to localized concentrations near traffic corridors and industrial areas.

Daytona Beach experiences a subtropical climate with distinct wet and dry seasons rather than traditional four seasons. Air quality generally improves during the wet season (May-October) due to frequent rainfall which effectively scrubs the atmosphere of pollutants. However, high humidity can also contribute to the formation of ground-level ozone, particularly during hot, sunny days. Pollution tends to peak in the late winter and early spring (February-April) when drier conditions and stable atmospheric patterns trap pollutants closer to the ground. Temperature inversions, common during these months, exacerbate this effect. Winds are generally from the east or southeast, carrying pollutants from the Atlantic and potentially from upwind urban areas. August and September, while humid, often see the cleanest air due to consistent sea breezes and rainfall. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit strenuous outdoor activity during peak pollution periods in late winter/early spring. November through January can also see periods of stagnant air. Monitoring wind patterns and avoiding exercise near high-traffic areas are crucial for maintaining respiratory health. Fog, common in cooler months, can trap pollutants, reducing visibility and impacting air quality locally.
