The months considered "fall" (or autumn) depend on whether you are using a meteorological astronomical calendar, as well as which hemisphere you are in. Fall in the Northern Hemisphere (Includes the USA, Canada, Europe, and most of Asia) Meteorological Fall
Perceived Start: The Tuesday after Labor Day (first week of September).
Perceived End: The day after Thanksgiving (late November), when Christmas decorations take over.
For planning (gardening, weather, events): Use meteorological fall (Sept–Nov) – it's more consistent.
For cultural or celestial events (harvest festivals, equinox celebrations): Use astronomical fall.
The Tropics (e.g., Florida, Hawaii, Singapore): There is no fall. You have a wet season and a dry season. The concept of "September, October, November" is purely academic.
High Latitudes (e.g., Alaska, Scandinavia): Fall lasts only 4 to 6 weeks. What is called "September" feels like winter. The fall months might effectively be August and September.
Mediterranean Climates (e.g., California, Spain, Italy): Fall extends later. October is often still warm (Indian Summer), and November is the first "cold" month. However, December often feels like late fall rather than true winter.
September: Northern states (Maine, Vermont, Minnesota) and Canada.
October: Mid-Atlantic states (New York, Pennsylvania, Virginia) and the UK.
November: Southern states (North Carolina, Georgia, Texas) and Southern Europe.
These three months represent the transitional period between the warmth of summer and the freezing cold of winter. In the Southern Hemisphere, due to the tilt of the Earth, the seasons are reversed. There, fall (often called "autumn") occurs during March, April, and May. what months are the fall
