Manhattanhenge has become one of the most celebrated events in New York City, when the sun lines up exactly with the Manhattan street grid. It happens twice a year, off the equinox, due to the angle of the Manhattan grid (28.9 degrees east of due north), offering incredible sunsets that fully illuminate the cross-streets.

This phenomenon has been nicknamed “Manhattanhenge” for its similarity to Stonehenge — but this moniker would imply a sense of mystery over the physical remnants and functionalities of a bygone civilization. Rather, this bi-annual occurrence is unique to Manhattan because of a fortuitous street plan and flat topography that, in concurrence, provide clear, straight views to the horizon.

There are some classic locations to watch Manhattanhenge, but it can get pretty crowded. Here, we offer both the off-the-beaten-path and tried and true places. Tonight’s (July 12th) rendition of the Full Sun version of Manhattanhenge will be at 8:20 PM, and tomorrow’s half sun (July 13th) will be at 8:21 PM.
