Why Fall Feels Like It Starts September 1, Not 22
• Meteorological fall, based on temperature cycles, begins September 1st, differing from the astronomical start around September 22nd.
• September brings noticeable weather shifts like declining temperatures and shorter daylight hours, aligning with the meteorological definition of fall.
• Cultural factors and personal experiences, such as the return to school and changing leaves, enhance the feeling that fall starts earlier than the astronomical equinox.
Meteorological versus astronomical seasons explain early fall feeling
Why does it often feel like fall begins on September 1st rather than the astronomically defined date of September 22nd or 23rd? The answer lies in the difference between meteorological and astronomical seasons. While the astronomical seasons are determined by the Earth's position relative to the sun, meteorological seasons are based on the annual temperature cycle.
