In the Northern Hemisphere (including North America, Europe, and most of Asia), autumn generally occurs in the latter part of the year. According to Britannica , it marks the transition from summer to winter.

| Hemisphere | Meteorological Months | Typical Vibe | | :--- | :--- | :--- | | | Sept, Oct, Nov | Cooling down, back to school, falling leaves. | | Southern | Mar, Apr, May | Cooling down, grape harvest, falling leaves. |

October is arguably the most iconic of the autumn season months. This is when "leaf-peeping" becomes a popular pastime as deciduous trees reach their peak vibrance.
