What this forecast looks for

Plain-language explanation from the rule

This forecast tracks the maritime fog and mountain mist that define New England's atmospheric photography. We combine ocean temperature, dewpoint, and topography to predict when coastal fog banks and mountain valley mist will create moody, quintessentially New England conditions.

New England sits where cold Atlantic waters meet the North American continent, creating persistent fog conditions especially during autumn. The region's mountains—from the White Mountains of New Hampshire to the Green Mountains of Vermont—also generate valley fog that transforms familiar scenes into ethereal compositions.

What makes New England fog photography exceptional:

  • Maritime fog - Cold Atlantic waters generate thick fog banks that roll inland, especially in Maine and coastal Massachusetts
  • White Mountains valleys - Notches and valleys trap morning mist that burns off by mid-morning, creating dramatic reveal moments
  • Covered bridge fog - Vermont and New Hampshire's iconic covered bridges emerge from fog like scenes from another century
  • Acadia coastal mist - Rocky Maine coast where fog meets granite cliffs and crashing waves

Best conditions occur September through October when warm land meets cooling air. Coastal fog can persist all day, while mountain valley fog typically burns off by late morning. Classic locations include Franconia Notch, Smugglers' Notch, and Mount Desert Island.
