Antarctica climate data and climate graphs Casey and Mawson Stations (Australia)

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, 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
