Twice a year, San Francisco puts on a dazzling celestial show known as California Henge. This is a phenomenon where the rising or setting sun aligns perfectly with the city’s street grid, casting a golden glow down California Street and illuminating the Bay Bridge in the distance.
What Is California Henge?
California Henge occurs when the position of the sun aligns with San Francisco’s east-west oriented streets, most notably California Street. As the sun rises or sets, it beams directly down the corridor framed by skyscrapers, creating a dramatic interplay of light and shadow. The effect is particularly striking when one of the Bay Bridge towers is silhouetted in the sun’s path, creating an iconic photo opportunity.
This phenomenon is named in homage to Manhattanhenge, a similar event in New York City, where the sunset aligns with the Manhattan street grid. Other cities with similar events include Bostonhenge and Chicago Henge, but California Henge has its own West Coast flavor, framed by the rolling hills, Victorian buildings, and a clear line of sight to the Bay Bridge.
When and Where to See It
In 2026, California Henge is expected to occur on April 9, 2026 according to a post by San Francisco-based photographer Sean Qiu in the San Francisco Bay Area Street Photography Facebook group. This date aligns with the spring equinox window, one of two times each year (the other being around the autumn equinox in early September) when the angle of the sun lines up with the street grid.
The best viewing spot is near the top of Nob Hill, looking east down California Street toward the Bay Bridge. One popular spot is at California St & Gough St. Early risers and sunset chasers alike gather here, hoping for clear skies and the perfect alignment. Aim to get there about 6:40 am.
