Ōmiyachō in Shizuoka reflects the flat Shizuoka Prefecture coastal plain position, with vehicle traffic on surrounding roads and the manufacturing and residential character contributing local sources. Consistent Pacific maritime breezes provide coastal ventilation, while summer photochemical ozone from the broader Shizuoka metropolitan corridor is the primary warm-season concern and the area generally maintains moderate Shizuoka coastal readings throughout most of the year.

Frequently Asked Questions
Is air quality bad in Ōmiyachō right now?
On 10 August 2026, overall air quality in Ōmiyachō is poor. AQI is the main air quality indicator at 68.3/100. Pollution peaks around 4:00 PM (O3: 68.3/100).
Will air quality be worse tomorrow in Ōmiyachō?
On 11 August 2026, air quality conditions in Ōmiyachō will be better than today, with AQI forecast at fair at 27.2/100. Pollution peaks around 4:00 PM (O3: 27.2/100).
When is air pollution at its worst in Ōmiyachō?
Pollution in Ōmiyachō typically rises when vehicle traffic, petrochemical and refining operations, along with light manufacturing combine, especially once warm, sunny weather takes hold. Heat and sunlight combine with emissions to form ozone at ground level. Onshore breezes usually help clear the air, but pollution can build up when winds are light.
Are air quality levels in Ōmiyachō 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.
