No, the sun is never directly overhead at midday in Memphis, Tennessee.

Here's why:

* Earth's Tilt: The Earth is tilted on its axis. This tilt causes different parts of the Earth to receive varying amounts of sunlight throughout the year.

* Tropic of Cancer: The sun is directly overhead at midday at locations that fall on the Tropic of Cancer, which is located at approximately 23.5 degrees north latitude.

* Memphis' Latitude: Memphis, Tennessee is located at approximately 35 degrees north latitude. This is further north than the Tropic of Cancer, meaning the sun will never be directly overhead.

While the sun may appear high in the sky at midday in Memphis, it will never reach the zenith (directly overhead) point.
