Ginowan's air quality reflects the central Okinawa Island Pacific Ocean coastal position adjacent to Marine Corps Air Station Futenma, with vehicle traffic on surrounding roads and the US military aviation operations generating elevated NOₓ alongside the surrounding dense urban residential character. Consistent Pacific trade winds provide outstanding maritime ventilation, while the Futenma air base's aviation operations represent the most distinctive local emission source and the island trade wind exposure generally maintains Ginowan at moderate Okinawa metropolitan readings.

Frequently Asked Questions
Is air quality bad in Ginowan right now?
On 21 September 2026, overall air quality in Ginowan is fair. AQI is the main air quality indicator at 38.7/100. Pollution peaks around 11:00 PM (O3: 38.7/100).
Will air quality be worse tomorrow in Ginowan?

When is air pollution at its worst in Ginowan?
Pollution in Ginowan typically rises when road traffic together with aircraft operations at the local air base combine, especially once onshore breezes fall calm. Sea breezes typically keep conditions in check, except during still weather. Areas further inland without this ventilation tend to fare worse.
Are air quality levels in Ginowan 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.
