Why would you not get a sun tan in Antarctica June?

You can't get a sun tan in Antarctica in June because the sun does not rise above the horizon during the Antarctic winter months. The sun is continuously below the horizon, resulting in 24 hours of darkness known as the polar night. This phenomenon occurs due to the Earth's tilt on its axis and its orbit around the sun, which causes the sun's angle of incidence on Antarctica to be too low for direct sunlight to reach the continent. As a result, there won't be enough ultraviolet radiation to cause a sun tan.
