What Is Christmas Like In Southeast Texas

Christmas is upon us again. It is a time to reflect and celebrate and be jolly. What is Christmas typically like in Houston? The Ghost of Christmas Past can either bring cold, warm, dry, or wet Christmas. There are no official records of snow on Christmas Day. The closest was on December 24, 2004, when it snowed a great deal, especially southwest of Houston, where Victoria got up to 13 inches of snow. It seems generally it is cold and clear on Christmas.

Here are weather records that goes back to 1921. Keep in mind that the official weather station for Houston has moved from Downtown Houston to Bush Interncontinental Airport.
