The “Lahaina Noon” is one of those phenomena that seems straight out of an optical illusion, but it is completely real. Twice a year, in Hawaii and other regions near the tropics, the Sun passes almost exactly overhead, causing vertical objects to cast minimal or practically invisible shadows.
The name lāhainā means “cruel sun” or “intense sun” in Hawaiian. During those minutes, poles, trees, and people seem to lose their shadows because the light falls completely vertically.
The phenomenon occurs only in places located between the tropics and depends on the Earth’s exact position relative to the Sun; it is pure astronomy and solar geometry. For many tourists, it is one of the strangest moments to witness.
