When the Sun Is Directly Overhead in Fort Worth, TX

In Fort Worth, Texas (~32.75°N), the sun reaches the zenith (directly overhead, 90° altitude) on three days per year when the solar declination matches the latitude:

• May 27
• July 16
• August 26

On these dates, solar noon (not clock noon) is when the sun is exactly overhead. Shadows vanish for vertical objects. This occurs between the Tropics of Cancer (23.44°N) and Capricorn; Fort Worth is just north of Cancer, so zenith occurs only near summer solstice.
