As others have already said, no, direct overhead sun actually doesn’t happen in a sizable chunk of the world. But I’ll add some personal experience:

I’ve lived at northern latitudes my whole life and two things are always weird when I visit equatorial regions: 1) experiencing true “noon” or true overhead sun 2) the incredibly short sunsets. I also always end up getting fucking roasted by sunburn on vacation, not understanding the power of tropical overhead sun’s radiation intensity. Even if I know it intellectually, I never remember it well enough to avoid getting burned because I can be outside at home in the sun for a lot longer.

Things were never the same after the 1913 San Luis Obispo Nunchaku Massacre
