When does summer 2023 begin? And when does it end?
On Wednesday, June 21, 2023, the Arab world and countries located in the northern hemisphere are witnessing the phenomenon of the summer solstice, announcing the start of the astronomical and official summer season. The summer season this year extends for 94 days until the autumnal equinox, which falls on Saturday, September 23, 2023. On Wednesday, June 21, the winter season begins in countries located in the southern hemisphere, such as Australia.
What happens on the summer solstice?
This year, the summer solstice falls on June 21 at 2:57 p.m.
in the most northwestern part of the globe. Because of this, the day is the longest day of the year, while the night is the shortest night of the year.
On the day of the summer solstice, the sun is entirely perpendicular to the orbit of Cancer, which is placed around 23.5 degrees north of the equator. This occurs because Cancer is located in the northern hemisphere.
Summer in meteorology starts from the beginning of June
This year, the astronomical beginning of summer will occur on June 21 and will continue until the autumnal equinox, which will take place on September 23. According to the principles of meteorology, the start of summer occurs at the same time each year at the beginning of the month of June, and it continues until the end of the month of August each and every year.
Why is summer longer than winter in number of days?
since of the earth's orbit around the sun, which is elliptical rather than circular, the world is at its most distant point from the sun at the beginning of January of each year.
This occurs during the winter season in the northern hemisphere, and since the earth then travels more quickly around the sun, the winter season lasts for a shorter amount of time (89 days).
When it comes to summer, the Earth is at its furthest point from the sun at the beginning of July.
After this point, the Earth goes through its orbit more slowly, which causes summer to continue for a total of 94 days.
On the other hand, in the Southern Hemisphere, the winter season lasts around five days longer than it does in the Northern Hemisphere.
This is because of the Earth's tilt.
