Is September considered the summer or fall?

Answer 1

It all depends on where you are, the northern hemisphere or the southern one. Generally speaking, in the northern hemisphere, September is considered the fall while in the Southern Hemisphere, September would be considered spring. However, the equinox marks the changes of seasons and September 22nd or 23rd is the normal date for the equinox. Therefore, prior to the equinox, September is technically summer in the northern hemisphere and changes to fall at the equinox. Conversely, in the southern hemisphere, prior to the equinox, September is considered winter and changes to spring at the equinox.

Answer 2

September is typically considered the transition month from summer to fall. The first part of September may still feel like summer with warm temperatures, but as the month progresses, the weather usually starts to cool down, and the colors of fall begin to appear.
