Winter is the coldest season of the year.Of the three winter months,january is usually the coldest one.Winter is my favorite season because of winter holidays.When winter approaches,it gets colder and the days get shorter.The temperatures often fall below 0 C,especially at night time.We usually get the first snow in December.In winter people wear warm clothes.Kids love winter.They play snowballs,build snowmen,ski and skate.
