Chantilly experiences air quality shaped by former coalfield industry and motorway traffic, in a setting close to the Somme, while North Sea winds sweep across the open plains, generally keeping conditions moderate to good on most days. Winter can see particulate build-up during still, cold spells, while summer generally benefits from stronger regional winds, aside from occasional cross-border ozone episodes.
