In the Northern Hemisphere, fall typically spans September, October, and November. If you are in the Southern Hemisphere, the seasons are reversed, meaning fall occurs during March, April, and May.
From the strict perspective of the Gregorian calendar and meteorological science, fall is a neat, tidy package of three months. In the Northern Hemisphere, meteorological fall is defined as September, October, and November. This definition is pragmatic, designed for scientists and climatologists who need consistent time frames to compile weather statistics and compare seasonal data year over year. By this standard, fall begins on the first of September and ends on the thirtieth of November. This categorization aligns well with the temperature cycles; by September first, the sweltering heat of August usually begins to break, and by late November, the chill of winter starts to settle in. For the planner and the statistician, fall is a finite quarter of the year. what months are fall in
Ask someone when fall begins, and you will likely receive one of two answers. One response is rooted in the rigid predictability of astronomy, while the other stems from the organic, shifting rhythms of the natural world. The question "what months are fall in" seems simple on the surface, yet the answer reveals a fascinating duality between how we measure time on paper and how we experience it in the air. Depending on whether you ask a meteorologist, an astronomer, or a poet, the months of fall shift, overlap, and redefine themselves. In the Northern Hemisphere, fall typically spans September,
If you live in Australia, New Zealand, South Africa, or much of South America, autumn officially begins in March. For these regions, the transition to cooler weather happens just as people in the North are preparing for spring flowers. Signs That Fall Has Arrived In the Northern Hemisphere, meteorological fall is defined
In summary, to determine when fall is, always note the hemisphere: for the north, March–May for the south.
To understand why these dates sometimes shift, we have to look at the two primary ways we define seasons: astronomical and meteorological. The Astronomical Definition
