Have you ever wondered about when the USA winter season starts? Then I got you covered.

Winter is one of my favorite seasons in the US. Many places are covered in a blanket of snow and houses are decorated to the brim.

But when does winter actually start? And how long does it last? And most importantly: where will I be able to see snow in winter in the US?

All of these questions and more will be answered in this post. I have taken a deep dive into books and databases to give you a great overview of what winter in America looks like.

Let’s get to it.

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.
