What Months Are The Fall
Scientists and forecasters divide seasons into two main categories: astronomical and meteorological. Each serves a different purpose, leading to different start and end dates. 1. Meteorological Fall (Based on the Temperature)
Under this system, winter begins precisely on December 1 (North) or June 1 (South). 2. Astronomical Fall (Based on the Earth's Orbit)
The astronomical calendar relies on the Earth's tilt and its position in orbit around the Sun. The beginning of fall is marked by the , which usually happens on September 22 or 23 in the Northern Hemisphere. On this specific day, the Earth's axis is tilted neither toward nor away from the sun, meaning day and night are almost exactly the same length. Astronomical fall runs until the Winter Solstice (around December 21), which is the shortest day of the year. The Meteorological Seasons what months are the fall
Meteorological seasons are based on the annual temperature cycle and the Gregorian calendar. Scientists divide the year into four equal three-month periods to make record-keeping easy. September, October, and November. Start date: September 1st. End date: November 30th. Astronomical Fall
The definition of (or autumn) depends on whether you are looking at the calendar through a scientific or a traditional lens. In the Northern Hemisphere, there are two main ways to mark the season: 1. Meteorological Fall (The Simple Way) Scientists and forecasters divide seasons into two main
By December 1, meteorologists consider the winter season to have officially begun, as this aligns with the coldest three-month period of the year. 2. Astronomical Fall (Based on the Earth's Orbit)
No matter which definition you use, fall remains one of the most beloved seasons for its cozy fashion, beautiful scenery, and the sense of a fresh start. Meteorological Fall (Based on the Temperature) Under this
If you live in or travel to the Southern Hemisphere, the seasons are completely reversed due to the tilt of the Earth's axis. When the top half of the planet tilts away from the sun, the bottom half tilts toward it. Meteorological Fall in the South
September acts as the bridge between summer and autumn. In many regions, the first half of the month still brings summer-like heat, often referred to as "Indian Summer." However, as the autumnal equinox approaches, the nights begin to cool down significantly, and the days grow noticeably shorter. Schools resume, harvest festivals begin, and the first hints of color appear on northern trees. October: Peak Autumn
