South Pole
In midsummer, as the sun reaches its maximum elevation of about 23.5 degrees, high temperatures at the South Pole in January average at . As the six-month "day" wears on and the sun gets lower, temperatures drop as well: they reach around sunset (late March) and sunrise (late September). In midwinter, the average temperature remains steady at around . The highest temperature ever recorded at the Amundsen–Scott South Pole Station was on Christmas Day, 2011, and the lowest was on June 23, 1982 (for comparison, the lowest temperature directly recorded anywhere on earth was at Vostok Station on July 21, 1983, though was measured indirectly by satellite in East Antarctica between Dome A and Dome F in August 2010). Mean annual temperature at the South Pole is -49.3 °C (-56.7 °F).
São Paulo
The record high temperature was on October 17, 2014 and the lowest on June 25, 1918. Temperature averages are similar to those of Sydney and Shanghai. The Tropic of Capricorn, at about 23°27' S, passes through north of São Paulo and roughly marks the boundary between the tropical and temperate areas of South America. Because of its elevation, however, São Paulo experiences a more temperate climate.
The city experiences four seasons. The winter is mild and sub-dry, and the summer is moderately warm and rainy. Autumn and spring are transitional seasons. Frosts occur sporadically in regions further away from the center, in some winters throughout the city. Regions further away from the center and in cities in the metropolitan area, can reach temperatures next to , or even lower in the winter.
