Weather of Arabia - Tomorrow, Thursday, 4 Dhu al-Hijjah 1442 corresponding to July 15, 2021 AD, the Kaaba will witness the phenomenon of the sun perpendicular to the Kaaba for the second time during the current year, at 12:27 noon Mecca time, when the shadow of the Kaaba and the shadow of things will disappear at that time. Almost in Mecca at this time.
The reason for the sun’s perpendicularity over the Kaaba is due to the tilt of the Earth’s rotation axis at an angle of 23.5 degrees, which leads to the sun moving “apparently” between the Tropics of Cancer in the north and the Tropic of Capricorn in the south, passing through the equator while the Earth revolves around the sun once every year.
Therefore, the regions located at latitudes less than 23.5 degrees north or south all witness the phenomenon of the sun perpendicular to it twice every year, but at different times it depends on the latitude of the place located in the region between the equator and the Tropic of Cancer in the north and the equator and the Tropic of Capricorn in the south.
The phenomenon of the sun perpendicular to the Kaaba occurs twice a year, the first is during the month of May, when the sun apparently moves north of the equator towards the Tropic of Cancer, when the sun passes over the latitude of Makkah Al-Mukarramah (21.425 degrees north), while the second time is during The month of July, when the sun returns in its apparent movement towards the south from the Tropic of Cancer to the equator, and passes over the latitude of Makkah Al-Mukarramah again.
