A cursory look on the internet for current Antarctic temperatures one evening this week revealed a temperature at the Amundsen-Scott base at the South Pole to be 103 degrees below zero Fahrenheit.
It is midwinter in the Southern Hemisphere. The South Pole will not even have daylight for several more weeks. At the Pole during July, the average high is 56 below and the average low is 80 below. The July record low is 113 below. The all-time record set in June is 117 below. The Russian station at Vostok holds the world low temperature record of 128.6 below.
These temperatures are so low because the South Pole sits on a glacier at 11,000 feet above sea level and is surrounded by higher mountains. Cold air is trapped inside the ring of mountains in the dark. Even in the continuous daylight of summer, the South Pole rarely gets above zero. Since 1956, the record high temperature is 9.9 degrees
