What is Summer Solstice?
•The Summer Solstice is a phenomenon that occurs when the Sun is directly over the Tropic of Cancer or 23.5 degrees north latitude.
•When the North pole is titled more towards the Sun, the Northern Hemisphere experiences the Summer Solstice during the months between March and September.
•The day of the beginning of the Summer Solstice can vary by a day or two. In 2019, the Summer Solstice was observed on June 21.
The Science behind the Summer Solstice
•Earth’s rotational axis is not exactly at a right angle to the planet’s orbital path around the Sun. The axis of our planet at which it spins is tilted at an angle of 23.5 degrees vertically in accordance with the Sun. This means the North and South poles of our planet are tilted too.
•When the North pole is titled more towards the Sun, the Northern Hemisphere experiences the Summer Solstice during the months between March and September. Whereas, when the North pole tilts farther from the Sun during the later half of the year, the Northern Hemisphere experiences the Winter Solstice.
•During the Summer Solstice in the Northern Hemisphere, the days receive long hours of daylight. In fact, the farther North you go for instance inside the Article Circle, within 25 degrees of the North Pole, you will see that the Sun never sets during the day of the summer solstice. The duration of daylight lasts up to six months in the North of the Arctic Circle during this time of year.
When is the Summer Solstice for Southern Hemisphere?
•The solstices are reversed in the Southern Hemisphere. The Summer Solstice comes in during late December while the Winter Solstice comes in during late June.
