Casey and Mawson
Temperature,
rainfall and wind speed information for stations in Antarctica
Conditions in Antarctica are sometimes on the face of it matched by
those elsewhere, particularly the cold. What makes Antarctica unique
however is the ever-present wind and the fact that it is
always cold. In other places with
continental climates for instance, cold is usually accompanied with
calm conditions - and extreme cold rarely lasts for very long.

If you want to translate these figures
into degrees Fahrenheit, the table can be copied and dropped into an Excel
spreadsheet and this formula applied:
Temperature in degrees
Fahrenheit = (Temperature in degrees centigrade x 1.8) + 32
