The Foggiest Place in the U.S. Is Right Here in Northern California

California is known for weather extremes, but one of its most surprising claims to fame isn’t heat or snow—it’s fog. And the foggiest place in the country isn’t San Francisco. That title belongs to Point Reyes National Seashore.

Located along the rugged coastline of Marin County, Point Reyes is wrapped in dense ocean fog for roughly 200 days a year, making it the foggiest spot in the United States. Only the Grand Banks off Newfoundland see more fog across all of North America.

The fog here isn’t just a light coastal haze. According to the National Park Service, massive sheets of marine fog can stretch up to 50 miles out over the Pacific Ocean, hugging the land and sea alike. Summer is peak fog season, when cold ocean currents collide with warmer inland air, creating the thick gray blanket that defines Point Reyes’ atmosphere.

Yet even with limited visibility, Point Reyes remains one of Northern California’s most beloved outdoor destinations, welcoming more than 2.3 million visitors each year. Rolling coastal meadows, forested ridgelines, crashing cliffs, and quiet beaches make the park feel wild and untouched.

On clearer days, hikers can take in sweeping views from Inverness Ridge, while foggy mornings add drama to spots like the Point Reyes Lighthouse and Drakes Beach, where elephant seals lounge along the shore. At Point Reyes, the fog isn’t a drawback—it’s part of what makes the place unforgettable.
