What is the summer solstice and when does it occur?

<p style=";text-align:left;direction:ltr">Arabia Weather - The Summer Solstice is known as the day on which summer begins astronomically, and this day is characterized by the longest day and shortest night of the year.</p><h2 style=";text-align:left;direction:ltr"> When does the summer solstice occur?</h2><p style=";text-align:left;direction:ltr"> Answer: The summer solstice occurs annually on <strong>June 20 or 21</strong> in the Northern Hemisphere, and on December 21 or 22 in the Southern Hemisphere, but what happens astronomically on this day? Why is it the longest day of the year? This is due to the tilt of the Earth&#39;s axis as it revolves around the sun, which changes the angle of falling of the sun&#39;s rays on the Earth throughout the year. As a result, the apparent points of sunrise and sunset change between north and south, so that the path of the sun in the sky becomes higher or lower during the year and on the day of the summer solstice. The sun reaches its northernmost point in the sky.</p><p style=";text-align:left;direction:ltr"> After the summer solstice, the sun appears to reverse its course and begin to head south, where this trend continues until it reaches its southernmost point on the winter solstice in December.</p><p style=";text-align:left;direction:ltr"> This astronomical event is accompanied by several phenomena on Earth, the most important of which are:</p><ul style=";text-align:left;direction:ltr"><li style=";text-align:left;direction:ltr"> The official start of summer</li><li style=";text-align:left;direction:ltr"> The sun rises in the far north-east and sets in the far north-west</li><li style=";text-align:left;direction:ltr"> The longest day and the shortest night</li><li style=";text-align:left;direction:ltr"> The shortest shadow and lack of afternoon shadow in areas located on the Tropic of Cancer</li></ul><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> To know the difference between the summer solstice and the winter solstice, and why is the summer solstice the longest day of the year? <a href="https://www.arabiaweather.com/ar/content/%D8%A7%D9%84%D8%A7%D9%86%D9%82%... here</a> </p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"><img alt="" src="/sites/default/files/uploads-2020/%D9%85%D8%A7%20%D9%87%D9%88%20%D8%A7%D9%84%D8%A7%D9%86%D9%82%D9%84%D8%A7%D8%A8%20%D8%A7%D9%84%D8%B5%D9%8A%D9%81%D9%8A%20%D9%88%D9%85%D8%AA%D9%89%20%D9%8A%D8%AD%D8%AF%D8%AB%D8%9F.PNG" style="width: 723px; height: 421px;" /></p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> See also:</p><p style=";text-align:left;direction:ltr"> <a href="https://www.arabiaweather.com/ar/content/%D9%85%D8%AA%D9%89-%D9%8A%D8%A8... does summer 2024 start and when does it end?</a></p><p style=";text-align:left;direction:ltr"> <a href="https://www.arabiaweather.com/ar/content/%D8%A7%D9%84%D8%A7%D9%86%D9%82%... solstice...what is it?
