Climate scientists require fixed three-month blocks (meteorological) to track global warming trends, compute monthly averages, and compare weather data across different decades accurately.
False. Only the meteorological system does this. The astronomical system, which is what most schools teach, starts seasons on the equinox/solstice (around the 20th-22nd). Saying "Summer starts June 1st" is correct for meteorology but incorrect for astronomy.

This paper aims to verify the alignment of months to seasons. It argues that our current system is a "dual reality": a statistical construct for record-keeping (meteorological seasons) coexisting with an ancient celestial tracking system (astronomical seasons).
The months for each season are generally agreed upon by meteorologists and astronomers. Here's a breakdown of the verified months for each season in the Northern Hemisphere:
Here is the verified breakdown of the months for each season according to both scientific standards. The Meteorological Calendar (Based on Temperature) The astronomical system, which is what most schools
While the Gregorian calendar is the global standard, many cultures around the world use seasonal definitions that do not fit neatly into the March-May or June-August boxes.
| Season | Meteorological Months | Astronomical Range (Approx.) | Key Characteristics | | :--- | :--- | :--- | :--- | | | March, April, May | Mar 20 – Jun 20 | Warming, blossoms, rain showers | | Summer | June, July, August | Jun 21 – Sep 22 | Hottest, long days, thunderstorms | | Autumn (Fall) | September, October, November | Sep 23 – Dec 21 | Cooling, leaves change, harvest | | Winter | December, January, February | Dec 21 – Mar 19 | Coldest, short days, snow/ice |
Begins around June 20 (Summer Solstice) and ends around September 22. Verified Months: June, July, August. Autumn (Fall) Meteorological: September 1 to November 30. It argues that our current system is a
Before diving into the specific months for each season, let's quickly review what each season is characterized by:
Transition period featuring cooling temperatures, shortening daylight hours, and senescence (color changes) in deciduous foliage. Months: December, January, February
The months assigned to each season depend on whether you use the or astronomical definition. Meteorologists use fixed three-month blocks based on the calendar and annual temperature cycles, while astronomers use the Earth's orbit and the sun's position (solstices and equinoxes). Meteorological Seasons (Calendar-Based)
The astronomical start date for a season can shift from year to year. "Astronomical spring is not always the same day," explains Alan Dunham of the National Weather Service. Furthermore, the inclusion of a leap day every four years adds to the complexity, causing the dates of the equinoxes and solstices to vary.
