Yanagawa's air quality reflects the Fukuoka Prefecture Ariake Sea coastal position at the Chikugo River delta canal city, with vehicle traffic on surrounding roads and the eel cuisine, tourism, and agricultural corridor contributing modest local sources. Consistent Ariake Sea maritime breezes provide ventilation, while the famous canal waterways and the broader Fukuoka metropolitan regional background maintain moderate Fukuoka Prefecture coastal corridor readings throughout most of the year.

Frequently Asked Questions

Is air quality bad in Yanagawa right now?

On 10 August 2026, overall air quality in Yanagawa is fair. AQI is the main air quality indicator at 27.6/100. Pollution peaks around 4:00 PM (O3: 27.6/100).

Will air quality be worse tomorrow in Yanagawa?

When is air pollution at its worst in Yanagawa?

Pollution in Yanagawa typically rises when traffic on the surrounding roads, farming and agricultural processing, and tourism-related traffic combine, especially once maritime winds die down. 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 Yanagawa 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.
