The beginning of summer, meteorologically or climatically

The climatic classification of the beginning of summer depends on average temperatures and global weather patterns. High-pressure systems begin to fully control the northern hemisphere at the beginning of June, and temperatures rise to summer levels. Hot weather becomes the norm across all regions of the northern hemisphere.

The year is also divided into four seasons, according to meteorological authorities. Each season lasts three full months. According to this division, summer begins climatically on June 1 and ends on August 31.

The beginning of astronomical summer

This depends on the Earth's movement around the sun. Astronomically, summer begins in the Northern Hemisphere when the sun is directly overhead at the Tropic of Cancer (23.5°N). This usually occurs on June 21 or 22 of each year. This day is known as the summer solstice, and it is the longest day and shortest night of the year.
