Winter is one of the four seasons. In winter, the days are short and the sun’s rays fall only obliquely on the earth. That’s why it’s cold in winter, and temperatures often drop below zero degrees Celsius.
It comes to frost. The water in lakes and streams freezes to ice, and snow often falls instead of rain. Many animals hibernate or are hibernating. Some bird species fly to warmer areas to overwinter.
For those who don’t live in the tropics, winter is the time of year to be prepared to eat and stay warm. Nowadays, however, most people don’t feel as bad about winter as they used to. Some even like it because then they can do winter sports or build a snowman.
From when to when does winter last?
For weather researchers, winter in the northern hemisphere begins on December 1st and lasts until February 28th or 29th. The winter months are December, January, and February.
For astronomers, however, winter begins at the winter solstice, when the days are at their shortest. That’s always on December 21st or 22nd, just before Christmas. Winter ends at the equinox when the day is as long as the night. That’s March 19, 20, or 21, and that’s when spring begins.
