Summer Solstice 2021 is on the horizon at a time when summers are at their peak in the Northern Hemisphere including Pakistan marking the longest day and shortest day of the year on Monday because the North Pole is tilted closest to the sun.

Summer Solstice is also the day when the sun reaches its highest point in the sky, due to which the daylight lasts longer than usual.

The report said that the sun will be overhead the Tropic of Cancer in the midday which means that daylight will last the longest in the year on June 21. NASA calls it the “beginning of astronomical summer.”

It may be mentioned that solstice, a Latin word, literally means ‘when the sun stands still’, because the sun is around for so long that it appears to be still, with the movement of the earth’s orbit notwithstanding.

When the summer solstice takes place in the northern hemisphere, the Sun will reach its highest possible point. Our planet does not spin on a vertical axis - it is titled. This means the amount of sunlight that reaches different regions of the Earth changes during the year as it orbits the Sun.
