In the Southern Hemisphere:

The Winter Solstice , which usually falls on December 21st or 22nd. 3. Southern Hemisphere Fall In the Southern Hemisphere, the seasons are reversed. Autumn: a burst of colour - Met Office what months are the fall
In many places, September is a blend of summer warmth and fall crispness. Early September still feels like summer, but as the equinox approaches (roughly the 22nd–23rd), temperatures drop, leaves begin to change in northern climates, and the days shorten rapidly. October: Peak Autumn
When we ask the question, "What months are the fall?" the answer is surprisingly complex. It depends entirely on whether you are asking a meteorologist, an astronomer, or simply looking out your window to see the leaves changing color. Southern Hemisphere Fall In the Southern Hemisphere, the
| Aspect | Astronomical Fall | Meteorological Fall | Perceptual / Cultural Fall | | :--- | :--- | :--- | :--- | | | Late Sept to Late Dec | Sept, Oct, Nov | Sept, Oct, Nov | | Start Date | Sept 21-24 | Sept 1 | After Labor Day (US) or school starts | | End Date | Dec 20-23 | Nov 30 | Before Thanksgiving or first snow | | Based On | Earth's orbit & tilt | Annual temperature cycle | Sights, sounds, & traditions | | Key Feature | Autumnal Equinox | Consistent data months | Fall foliage & harvest holidays |
Both are correct, depending on your system. September 1 is the start of meteorological fall. September 22 or 23 is the start of astronomical fall. Neither is "wrong"—they're just different tools for different purposes. October: Peak Autumn When we ask the question,

If you ask an astronomer, they will say:
This fixed schedule allows scientists to compare weather statistics from year to year more easily. It also better reflects the transition from summer’s heat to winter’s chill. 2. Astronomical Fall: Late September to Late December
