Heerhugowaard's air quality reflects the flat North Holland polder landscape adjacent to Alkmaar, with vehicle traffic on the A9 motorway and the surrounding suburban and logistics industry contributing local sources. The flat Dutch coastal terrain provides reasonable dispersal, while consistent North Sea westerlies carry relatively clean Atlantic air and the surrounding bulb-field and greenhouse agriculture contributes localised NOₓ from gas heating, generally maintaining Heerhugowaard at moderate Dutch urban air quality levels throughout the year.
