Tsurugashima's air quality reflects the flat Saitama southern Shingashi River plain adjacent to Kawagoe, with vehicle traffic on surrounding roads and the manufacturing and residential character contributing local sources. The flat Kanto Plain allows reasonable dispersal, while the broader Tokyo metropolitan regional emissions elevate background and summer photochemical ozone is the primary warm-season concern and Tsurugashima generally maintains moderate Tokyo northwestern Saitama suburban readings throughout most of the year.

Frequently Asked Questions
Is air quality bad in Tsurugashima right now?
On 17 August 2026, overall air quality in Tsurugashima is fair. O3 is the main pollutant at 38.7/100. Pollution peaks around 11:00 PM (NO2: 49.1/100).
Will air quality be worse tomorrow in Tsurugashima?
On 18 August 2026, air quality conditions in Tsurugashima will be similar to today, with SO2 forecast at fair at 37.2/100. Pollution peaks around 11:00 PM (NO2: 56.5/100).
When is air pollution at its worst in Tsurugashima?
Air quality in Tsurugashima tends to be worse when traffic on the surrounding roads, heavy industrial and chemical processing, together with manufacturing and food processing build up and summer heat and strong sunlight build up. Strong sunlight reacting with local emissions drives up ground-level ozone. Readings are generally lower during the cooler, cloudier months.
Are air quality levels in Tsurugashima 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.
