This forecast tracks the temperature inversions and fog conditions that create some of the most dramatic mountain photography in North America. We combine atmospheric data with local topography to predict when Bow Valley inversions will trap fog below while peaks glow above.

The Canadian Rockies are famous for their autumn morning fog, particularly in the Bow Valley corridor between Banff and Lake Louise. Cold mountain air settles into valleys overnight, creating thick fog layers that can persist until mid-morning, especially in September and October.

What makes Rockies fog photography exceptional:

  • Bow Valley inversions - Temperature inversions create sea-of-fog conditions with peaks emerging above the cloud layer
  • Glacier lake mist - Moraine Lake and Lake Louise develop ethereal mist at dawn when water temperatures meet cold air
  • Castle Junction phenomena - Junction areas where valleys meet create reliable fog formation zones
  • Autumn intensity - September through October brings the most dramatic and frequent fog events

Best shooting occurs at elevated viewpoints like Tunnel Mountain or Sulphur Mountain during inversions, or directly at lake level during misty conditions. Our forecast identifies when these different fog types will occur.
