  • The prior record high temperature at South Pole was recorded on 27 December 1978, not on 12 December 1978, as misquoted in some sources.
  • Preliminary assessment of ┬áthe record high at Nico AWS was -8.2C or 17.2F on 25 December 2011. ┬áThis breaks the previous known record of -13.9C or 7F recorded on 4 January 2010.
  • Preliminary assessment of the record high at Henry AWS was -8.9C or 16F on 25 December 2011. This break the previous known record of -14.5C or 5.9F on 5 January 2010.

*These are preliminary as AWS observations are still being reviewed during the 2003 to 2008 time period.

* Nico and Henry AWS are approximately 100 kilometers to the grid East and grid North of South Pole.
