That source has got very confused somewhere. The record low for the South Pole was -82.8C   (-117F) in June 1982, and every month from April to September has recorded temperatures below -100F. (Weatherbase historical).

If it's referring to a daily record, it doesn't mean much in this context.

I will follow on from this. I am reasonably certain that I have read that the lowest temperature for Mars at its poles is around -140 degrees C. measured from orbiting satellite.
Anyway,I thought that I would be an ordinary, intelligent person, searching,  so I did a quick Google search and found all sorts of figures, paraded as fact and few of them close.
One site had  a NASA logo on its mast head, and was an educational site and it told me that Mars was the closest planet...it just got worse, as I skimmed through other sites...
wiki answers or some such told me the maximum temperature was 6800 F
Couple of NZ based sites, for kids, quoting degrees F....
The current ground based machines on Mars have figures and they are pretty extreme but they are not at the Poles....
