Worst air pollution Fukushima, today and tomorrow
Today (16 July): Air quality in Fukushima is fair. NO2 and PM1 are fair; AQI and O3 are medium; PM2.5, PM10, SO2, CO, and HCHO are good. Pollution peaks around 12:00 PM (O3: 51.4/100).
Tomorrow (17 July 2026): Air quality in Fukushima is fair. AQI worsens to fair; O3 increases to fair; PM1 decreases to good; all other pollutants stay as today. Pollution peaks around 12:00 PM (O3: 31.9/100). Airmine updates local air quality forecasts four times daily.

Fukushima's air quality reflects the Fukushima Prefecture Abukuma River valley position, with vehicle traffic on surrounding roads and the manufacturing, food processing, and recovery corridor contributing local sources. Pacific coastal maritime breezes provide background ventilation, while the extraordinary context of the 2011 Fukushima Daiichi nuclear disaster's radiological legacy continues to shape the broader local environmental awareness and Fukushima generally maintains moderate Fukushima corridor readings throughout most of the year.

Frequently Asked Questions
Is air quality bad in Fukushima right now?
On 16 July 2026, overall air quality in Fukushima is fair. PM1 is the main pollutant at 23.1/100. Pollution peaks around 12:00 PM (O3: 51.4/100).
Will air quality be worse tomorrow in Fukushima?
On 17 July 2026, air quality conditions in Fukushima will be similar to today, with AQI forecast at fair at 31.9/100. Pollution peaks around 12:00 PM (O3: 31.9/100).
When is air pollution at its worst in Fukushima?
Fukushima usually sees its poorest air quality when road traffic together with manufacturing and food processing coincide with periods when maritime winds die down. Maritime airflow normally ventilates the area well, though calmer spells let levels rise. This natural ventilation is one reason coastal areas often see better readings than inland cities.
Are air quality levels in Fukushima 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.
