What is the sun altitude at solar noon?

The sun's altitude at solar noon is the highest point it reaches in the sky for a given location on Earth. This angle varies based on the observer's latitude and the time of year, reaching its maximum at the summer solstice. At solar noon, the sun is directly overhead at the Tropic of Cancer (23.5° N) and the Tropic of Capricorn (23.5° S) during their respective solstices, while locations outside these tropics will see the sun at an angle lower than 90 degrees.
