Does the sun ever go directly overhead?
Quick Answer: Yes, the sun can be directly overhead, but only between the Tropic of Cancer and Tropic of Capricorn. This happens when the sun reaches its highest point in the sky at solar noon, which varies by location and date.
The sun appears directly overhead only in the tropics, between about 23.5° north and 23.5° south latitude. This is because the Earth's tilt causes the sun’s position to shift north and south throughout the year.
At solar noon, the sun is at its highest point in the sky for that day. If you are within the tropics, the sun will be exactly at the zenith (right above you) on certain days when the sun’s declination matches your latitude.
