In these areas, "winter" and "summer" are replaced by "rainy" and "sunny," and the transition is often much more dramatic than a change in leaf color. 4. Cultural and Regional Variations Not every culture subscribes to the four-season model.
The division of months per season typically depends on whether you are following a or astronomical calendar. In most four-season systems, each season lasts exactly three months . Meteorological Seasons
The meteorological system is the simpler and more practical approach for climatology, weather forecasting, and agricultural planning. It divides the year into four seasons of three full calendar months each, based on the annual temperature cycle.
: Starts with the Autumnal Equinox (approx. September 22)
If you live near the equator, the concept of "four seasons" doesn't really apply. Instead of temperature swings, these regions experience changes in rainfall. Most tropical climates have only two seasons: Typically lasts about six months . The Dry Season: Typically lasts the other six months .
Understanding the "months per season" helps us align our lives with the planet. Whether you're a farmer timing your harvest, a data scientist tracking climate change, or just someone trying to decide when to put away their heavy coat, the rhythm of the seasons remains the heartbeat of human activity.
For most practical, day-to-day purposes (planning, clothing, agriculture, energy use), the meteorological 3-month season is preferred. For traditional or celestial events, the astronomical system remains authoritative. Neither is wrong; they simply serve different functions.
Meteorologists divide the year into four equal three-month periods based on the temperature cycle and the Gregorian calendar. This makes it easier to track seasonal statistics. : March, April, May Summer : June, July, August Autumn : September, October, November Winter : December, January, February Astronomical Seasons
