Odawara's air quality benefits from its exceptional Sagami Bay and Pacific Ocean coastal position in Kanagawa Prefecture, with consistent Pacific and Sagami Bay maritime breezes providing reliable ventilation. Vehicle traffic on surrounding roads and the Kamaboko fish cake manufacturing, manufacturing, and historical castle tourism corridor contribute local sources, while the outstanding Pacific coastal exposure and the Hakone volcanic highlands rising dramatically inland create dramatic topographic variation and Odawara generally maintains moderate to good conditions throughout most of the year.

Frequently Asked Questions
Is air quality bad in Odawara right now?
On 10 August 2026, overall air quality in Odawara is poor. AQI is the main air quality indicator at 68.1/100. Pollution peaks around 3:00 PM (O3: 68.1/100).
Will air quality be worse tomorrow in Odawara?
On 11 August 2026, air quality conditions in Odawara will be better than today, with AQI forecast at fair at 33.8/100. Pollution peaks around 2:00 AM (NO2: 33.8/100).
When is air pollution at its worst in Odawara?
Pollution in Odawara typically rises when road traffic, textile and manufacturing operations, along with tourism-related traffic combine, especially once onshore breezes fall calm. Onshore breezes usually help clear the air, but pollution can build up when winds are light. This natural ventilation is one reason coastal areas often see better readings than inland cities.
Are air quality levels in Odawara 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.
