What this forecast looks for
Plain-language explanation from the ruleThe Netherlands' unique below-sea-level geography creates exceptional fog conditions as the polder landscape—land reclaimed from the sea—traps cold, moist air in natural depressions. This creates persistent valley fog and radiation fog that transforms windmills and waterways into ethereal scenes.
Kinderdijk's 19 UNESCO windmills rising from morning mist create one of photography's most iconic Dutch scenes. The flat terrain and extensive water networks mean fog forms readily on calm, clear nights and can persist well into morning. Marken's historic harbor on the Markermeer lake experiences frequent sea fog rolling in from the IJsselmeer.
What makes Dutch fog photography exceptional:
- Windmill emergence - Historic structures appearing gradually as fog lifts from polder basins
- Canal diffusion - Amsterdam and Leiden's canals create soft, atmospheric street scenes in fog
- Flat persistence - Lack of topography means fog lingers longer than in hilly regions
- Autumn reliability - October-November offer most consistent radiation fog conditions
Best fog occurs on calm, clear nights following daytime warmth—typically spring and autumn. Arrive before sunrise to catch densest conditions. The polders around Kinderdijk, Zaanse Schans windmills north of Amsterdam, and the Alblasserwaard region are prime locations. Fog typically burns off by 10-11 AM as temperatures rise.
