3. Street grid orientation
The phenomenon referred to as Manhattanhenge, including the projected event in 2025, owes its existence directly to the specific orientation of Manhattan’s street grid. The grid, which is not aligned precisely with the cardinal directions, deviates by approximately 29 degrees east of true north. This deviation is not merely a geographical curiosity; it is the fundamental cause enabling the solar alignment that characterizes Manhattanhenge. Were the grid perfectly aligned with north-south and east-west, the sun would not, at any point in the year, set directly in line with the streets.
The practical consequence of this angular offset is the creation of two distinct periods annually, near the summer solstice, when the setting sun aligns with the east-west streets. Without this specific grid orientation, such an alignment would be geometrically impossible within the city’s layout. Consider, for example, the street grids of other major cities like Chicago or Philadelphia, which are aligned closer to the cardinal directions. These cities do not experience a similar phenomenon because the necessary angular relationship between the street alignment and the sun’s path is absent. Therefore, the street grid orientation is not simply a contributing factor; it is the necessary and sufficient condition for Manhattanhenge to occur.
In summary, the unique street grid orientation of Manhattan is indispensable to the manifestation of Manhattanhenge, including the anticipated iteration in 2025. Its absence would preclude the possibility of the sun aligning with the streets in the manner observed.
