Antarctica is the coldest, driest and windiest continent on Earth. This graph shows the annual temperatures and seasonal variation at three locations in Antarctica - the research bases Bernardo O'Higgins (Chile - on the Antarctic Peninsula), Scott Base (New Zealand - Ross Island) and one of the coldest places on the planet - the Vostok station (Russia - at the center of the East Antarctic Ice Sheet). The surface temperatures are long term averages over all available data.
