1. Winter Season USA: Meteorological
In the USA the meteorological winter season runs from December 1 to February 28 or 29 (depending on leap year). So the winter months according to this are December, January, and February.
The Meteorological seasons are based on the calendar and average temperatures. It has nothing to do with the astronomical stuff like solstices.
This way it is easier for weather researchers to keep track of stats and trends. The meteorological seasons are the same each year.

2. Winter Season USA: Astronomical
Astronomical winter in the USA starts around December 21 and ends around March 20.
The dates can vary a bit each year. This way of measuring the seasons is based on the position of the Earth relative to the Sun.
So here’s how it works: The Earth is tilted on its axis, right? When the Northern Hemisphere is tilted away from the Sun, that’s when astronomical winter happens.
It starts on the winter solstice which is the shortest day of the year. Winter season in the USA ends on the vernal equinox, when day and night are about the same length.
Unlike meteorological winter, this one’s not about average temps or calendar dates. It’s all about how Earth moves around the Sun.
This way of measuring is less convenient for scientists and researchers.

Winter in the USA is magical, one of my favorite seasons.
In the USA, the winter months are December, January and February. It’s a chilly time of year when you can enjoy cozy moments indoors or explore winter wonderlands in various states. Great for experiencing different cultures and holiday festivities!
The United States experiences four distinct seasons: spring, summer, fall (autumn), and winter. Spring brings blossoming flowers, while summer is hot and sunny. Fall is famous for colorful foliage, and winter offers snow and chilly temperatures. Each season has its unique charm and activities.
November in the USA isn’t considered the full-blown winter season. It’s more like the transition period from fall to winter. While some northern states might experience early snowfall, others can still have milder temperatures. So, November varies, but it’s not quite winter yet!
Winter in the Northern Hemisphere typically starts around December 21st and lasts until March 20th. During this time, many regions experience colder temperatures, shorter days, and, in some areas, snowfall. It’s a season known for its cozy vibes and winter activities!
Winter in the Southern Hemisphere generally spans from June 21st to September 22nd. This is when countries like Australia, New Zealand, and parts of South America experience colder temperatures and shorter days, opposite to the Northern Hemisphere’s seasons. It’s a great time for skiing and other winter sports down south!
es, December in the USA can be quite cold, especially in the northern states and higher elevations. Many regions experience chilly temperatures, and some areas may even have snowfall, creating a festive and wintry atmosphere. It’s a cozy time of year.
Many parts of the USA, particularly in the northern states and mountainous regions, often have snow at Christmas. This snowy backdrop adds to the holiday charm and is associated with traditional Christmas imagery. However, in southern and coastal areas, it’s less common to have a white Christmas, as temperatures are milder. So, it varies by region.
The coldest month in the USA varies depending on the region. In many northern states, January is typically the coldest month, with the lowest temperatures and the most snowfall. However, in some areas, especially in the central and western parts of the country, February can also be bitterly cold. So, it varies, but generally, it’s during the winter months of January and February.
