Okinawa's air quality benefits from its exceptional central Okinawa Island 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 US military base complex operations and tourism corridor contribute local sources, while the extraordinary island trade wind exposure and the multiple military base corridor's aviation emissions represent the most distinctive local emission dynamic throughout most of the year.

Frequently Asked Questions
Is air quality bad in Okinawa right now?
On 10 August 2026, overall air quality in Okinawa is fair. AQI is the main air quality indicator at 22.8/100. Pollution peaks around 12:00 AM (O3: 22.8/100).
Will air quality be worse tomorrow in Okinawa?
On 11 August 2026, air quality conditions in Okinawa will be better than today, with AQI forecast at good at 19.8/100. Pollution peaks around 3:00 PM (O3: 19.8/100).
When is air pollution at its worst in Okinawa?
Pollution in Okinawa typically rises when traffic emissions, military aviation activity, and tourism-related traffic combine, especially once the sea breeze weakens. Maritime airflow normally ventilates the area well, though calmer spells let levels rise. This coastal advantage is less pronounced during still, high-pressure weather.
Are air quality levels in Okinawa 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.
