Global Temperature Extremes

The week’s hottest temperature was 43.9 degrees Celsius at Jeddah, Saudi Arabia.

The week’s coldest temperature was minus 64.4 degrees Celsius at Vostok, Antarctica.

Temperatures were tabulated from the more than 10,000 worldwide synoptic weather stations. The United Nations World Meteorological Organization sets the standards for weather observations, and provides a global telecommunications circuit for data distribution.

Icy Antarctica

The U.S. Snow and Ice Data Center says that the last six months in Antarctica, most of it spent in the southern winter’s polar darkness, were the coldest on record.

It calculated that the average temperature during the period was minus 77.6 degrees Fahrenheit. The Amundsen-Scott South Pole Station also recorded its second-coldest June-August period on record, behind only 2004 in the station’s 60 years of weather records. The chill was due to two periods of very strong winds encircling the continent, and a strong polar vortex.
