Den Helder's air quality benefits from its exceptional North Sea coastal exposure at the northern tip of North Holland, with some of the Netherlands' most powerful North Sea westerlies providing outstanding maritime ventilation across this major naval port city. Vehicle traffic on the A9 and the Royal Dutch Navy base operations contribute local sources, while the extraordinary North Sea exposure and the Den Helder peninsula's position on Holland's northernmost point generally maintain excellent to good coastal conditions throughout most of the year.
