Defining the End of Summer

The end of summer can be defined in a few different ways:

• Astronomical Summer: This is based on the Earth's orbit and the summer solstice. It marks the period when the Northern Hemisphere is most tilted toward the Sun.
• Meteorological Summer: This definition is used by meteorologists and climatologists. It defines summer as the months of June, July, and August for consistent tracking of seasonal weather patterns.
