Alkmaar's air quality is generally good, with North Sea westerlies providing reliable maritime ventilation across this historic North Holland cheese market city. Vehicle traffic on the A9 motorway and surrounding bulb-field and greenhouse agriculture contribute the primary local sources, while the flat Dutch coastal polder landscape and open North Sea fetch generally allow good dispersal throughout most of the year.
