Meteorological fall is a three-month period that runs from September through November, which tells meteorologists that the fall season is here.
Using a fixed date ensures consistency when comparing records over the years and avoids shifting dates every season, also aligning with the annual temperature cycle.
Meteorological fall is a data-driven season which is used across weather and climate science.
On the other hand, Astronomical fall is determined by the position of the Earth in relation to the sun rather than climate science.
Astronomical fall starts on the autumnal equinox which occurs when the sun's rays are directly over the equator and ends with the winter solstice. Lasting between 89 and 93 days reflects the natural orbit in space rather than the calendar months.
Astronomical fall starts on Sept. 22 and lasts through Dec. 21.
According to Chief meteorologist Tim Miller, “we may experience a small taste of fall a few times this month, but I’m predicting a continuation of above-average temperatures overall for September.”
However, optimists still hold out for cooler temperatures by the end of the month. Continuing grabbing the pumpkin spiced drinks but don’t forget to stay updated on the fall season online at South Carolina ETV and Public Radio.
