Nobody lives in the Antarctic, there are no cities or towns there. There are research stations and bases, where expeditioner’s stay temporarily for periods of a few months to 2 years. Although 1 year is usually more the case for “winterers”.
I was lucky enough to spend an extended summer at the Australian Davis station, in 2003/4. 48F (8.8c) is not a temp you see at Davis very often, as I recall we only had one day in Feb when it got that warm, this was also a clear blue sky and no wind day. We actually had a beach party outside with people getting around in shorts and board shirts. At lower more usual summer temps of 2-4c, again if there’s no wind, people often get around the base in normal street cloths. In part because the air is so dry, cooler temps like 2-4c can seem much warmer than places with higher moisture content in the air.
