Sakata's air quality benefits from its exceptional Yamagata Prefecture Sea of Japan coastal position at the Mogami River delta, with consistent Sea of Japan maritime breezes providing reliable ventilation. Vehicle traffic on surrounding roads and the rice, sake, and port corridor contribute local sources, while the outstanding coastal exposure and the Dewa Mountains rising inland create topographic variation and Sakata generally maintains good to moderate conditions for a major Japanese Sea of Japan coastal city throughout most of the year.

Frequently Asked Questions

Is air quality bad in Sakata right now?

On 10 August 2026, overall air quality in Sakata is fair. AQI is the main air quality indicator at 27.3/100. Pollution peaks around 2:00 PM (O3: 27.3/100).

Will air quality be worse tomorrow in Sakata?

When is air pollution at its worst in Sakata?

Pollution in Sakata typically rises when vehicle traffic as well as shipbuilding and port operations 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 Sakata 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.
