what month is fall season

Fall season, also known as autumn, is defined differently depending on the method used. According to the meteorological definition, fall season runs from September 1 to November 30 in the Northern Hemisphere. This definition is based on the annual temperature cycle and the months that include the equinoxes and solstices. On the other hand, the astronomical definition uses the dates of equinoxes and solstices to mark the beginning and end of the seasons. According to this definition, fall season starts with the autumnal equinox, which usually falls on September 22 or 23 in the Northern Hemisphere, and ends on the winter solstice, which usually falls on December 21 or 22.
