The equinox marks the moment when the sun is directly above the equator, resulting in nearly equal hours of daylight and darkness across the globe. Following this point, the Northern Hemisphere tilts further away from the sun, days grow shorter, and the solar definition of autumn begins. For purists, this is the only legitimate answer: summer lasts until the very last second of the final day before the equinox. However, this definition often feels disconnected from the lived reality of late August and early September, when the days have already begun to cool.
It is also important to acknowledge that the end of summer is geographically relative. In northern states like Minnesota or Maine, summer may feel "over" by mid-September as leaves begin to turn and temperatures drop into the 50s. Conversely, in southern states like Texas or Florida, summer heat often persists well into October. In these regions, the astronomical and meteorological end dates serve as formalities, while the sensible end of summer—the relief from high humidity—remains weeks away. when does summer end in america
