Hyères' air quality benefits from its exceptional Mediterranean Côte d'Azur coastal position adjacent to the Îles d'Hyères, with consistent Mistral wind events and Mediterranean sea breezes providing reliable ventilation. Vehicle traffic on the A57 and the Toulon-Hyères Airport's aviation operations contribute local sources, while the Maures massif creates dramatic topographic variation and the outstanding Mediterranean coastal exposure and frequent Mistral events generally maintain Hyères among the Côte d'Azur's more reliably ventilated coastal environments throughout the year.

Is air quality bad in Hyères right now?
On 9 August 2026, overall air quality in Hyères is poor. AQI is the main air quality indicator at 64.1/100. Pollution peaks around 6:00 PM (O3: 64.1/100).
Will air quality be worse tomorrow in Hyères?
On 10 August 2026, air quality conditions in Hyères will be better than today, with NO2 forecast at fair at 23.3/100. Pollution peaks around 3:00 PM (O3: 51.4/100).
When is air pollution at its worst in Hyères?
Residents in Hyères tend to notice the most discomfort when tourist traffic and coastal industry build up alongside the spring peak in plane and pine pollen; the Mistral wind provides powerful periodic ventilation, which typically keeps things from getting worse for long. Nearby Provencal farmland and garrigue scrub add a further seasonal factor.
Are air quality levels in Hyères 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.
