Izumi in Kagoshima reflects the Kagoshima Prefecture Yatsushiro Sea and Izumi Bay coastal position famous for the extraordinary Siberian crane wintering flock, with vehicle traffic on surrounding roads and the crane conservation tourism, agricultural, and residential character contributing modest local sources. Consistent Yatsushiro Sea maritime breezes provide coastal ventilation, while the outstanding coastal exposure and the internationally significant crane habitat generally maintain Izumi at moderate to good conditions for a Japanese southwestern coastal city throughout most of the year.

Frequently Asked Questions
Is air quality bad in Izumi right now?
On 10 August 2026, overall air quality in Izumi is fair. AQI is the main air quality indicator at 21.6/100. Pollution peaks around 11:00 PM (NO2: 21.6/100).
Will air quality be worse tomorrow in Izumi?
On 11 August 2026, air quality conditions in Izumi will be similar to today, with AQI forecast at fair at 28.0/100. Pollution peaks around 5:00 AM (NO2: 28.0/100).
When is air pollution at its worst in Izumi?
Air quality in Izumi tends to be worse when vehicle traffic, farming and agricultural processing, and seasonal tourism traffic build up and maritime winds die down. Onshore breezes usually help clear the air, but pollution can build up when winds are light. This coastal advantage is less pronounced during still, high-pressure weather.
Are air quality levels in Izumi 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.
