Astronomical summer, on the other hand, is based on the position of the Earth in its orbit around the Sun. In the Northern Hemisphere, astronomical summer starts on the summer solstice (around June 20th or June 21st) and ends on the autumnal equinox (around September 22nd or September 23rd).
Meteorological summer in the Northern Hemisphere consistently begins on June 1 and ends on August 31, aligning with the Gregorian calendar for statistical consistency. Unlike the astronomical season based on the summer solstice, this three-month block represents the warmest period of the year and differs from the Southern Hemisphere's summer, which runs from December 1 through February.
