Seogwipo's air quality benefits from its exceptional Jeju Island southern Pacific Ocean and East China Sea coastal position, with consistent northeast and southwest Pacific trade winds providing outstanding maritime ventilation. Vehicle traffic on surrounding roads and the Hallasan National Park tourism and citrus farming corridor contribute modest local sources, while the extraordinary island coastal exposure and the UNESCO World Heritage Jeju volcanic landscape generally maintain Seogwipo among Korea's cleaner coastal resort environments throughout most of the year.

When is air pollution at its worst in Seogwipo?
Seogwipo usually sees its poorest air quality when traffic on the surrounding roads, agricultural activity, along with seasonal tourism traffic coincide with periods when onshore breezes fall calm. Onshore breezes usually help clear the air, but pollution can build up when winds are light. This natural ventilation is one reason coastal areas often see better readings than inland cities.
Are air quality levels in Seogwipo 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.
