Arab Weather - After the beginning of June of each year, summer begins climatically in the northern hemisphere, or what is known as the beginning of summer from a meteorological perspective.

Here we must differentiate between the beginning of summer from a meteorological or meteorological perspective and the beginning of summer from an astronomical perspective, and what are the criteria followed in this regard.

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.

Conclusion

  • Depends on the position of the Earth and the Sun
  • Start June 21-22
  • Astronomical calculations and the solar calendar

Summer climate

  • Depends on temperature and weather
  • Start June 1
