Nice's air quality benefits from its Côte d'Azur coastal position, with consistent Mediterranean sea breezes from the sea and periodic Mistral wind events providing natural ventilation. However, the enclosed Var coastal plain between the Maritime Alps and the sea can trap vehicle and tourist traffic emissions under summer anticyclonic calm conditions, while the dense summer tourism season concentrates road and maritime traffic emissions along the Promenade des Anglais corridor.

Frequently Asked Questions
Is air quality bad in Nice right now?
On 9 August 2026, overall air quality in Nice is poor. AQI is the main air quality indicator at 77.3/100. Pollution peaks around 5:00 PM (O3: 77.3/100).
Will air quality be worse tomorrow in Nice?
On 10 August 2026, air quality conditions in Nice will be similar to today, with AQI forecast at poor at 64.0/100. Pollution peaks around 4:00 PM (O3: 64.0/100).
When is air pollution at its worst in Nice?
In Nice, the worst combined pollen and air quality days tend to come when tourist traffic and coastal industry coincide with the peak plane and pine pollen season in spring; the Mistral wind provides powerful periodic ventilation, so conditions usually improve within a day or two. Nearby Provencal farmland and garrigue scrub add a further seasonal factor.
Are air quality levels in Nice 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.
