Myrtle Beach's air quality benefits from its direct Atlantic Ocean coastal exposure, with consistent onshore sea breezes providing reliable maritime ventilation along the Grand Strand's long straight shoreline. The primary local concerns are vehicle emissions from US-501 and the tourism-concentrated US-17 Business corridor during peak summer season, and occasional wildfire smoke from the surrounding South Carolina coastal plain forests, while the flat coastal position prevents significant topographic pollution accumulation.

When is air pollution at its worst in Myrtle Beach?

Myrtle Beach's air quality has a clear seasonal rhythm: the cleanest conditions usually arrive in winter, once the humid summer ozone season has ended, but summer heat combined with the region's dense forest cover drives an extended ozone season. Occasional agricultural or prescribed-burning smoke can add short-lived particulate spikes outside the main summer ozone season.

Are air quality levels in Myrtle Beach based on measurements or forecasts?

It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.

Why doesn’t the forecast always reflect wildfire impacts?

Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.

During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
