⚠ Afternoon thunderstorms can develop quickly on humid August days, inland near the river valley. Lightning is a real concern on exposed summits in Acadia if you are hiking Cadillac or Champlain Mountain. Check forecasts before committing to ridge-line hikes. Be below treeline by early afternoon.
⚠ Fog can roll in from the coast and settle over the Penobscot Valley overnight, reducing visibility on morning drives toward Bar Harbor and Acadia. The fog typically burns off by 9 or 10 AM, but if you are driving the park roads at dawn for a Cadillac Mountain sunrise, take the curves slowly. Expect limited sightlines until you climb above the fog line.
