As of September 14, 2015, twelve nations or territories tied or set all-time records for their hottest temperature in recorded history in 2015, and two (Israel and Cyprus) set all-time cold temperature records. For comparison, only two nations or territories set all-time heat records in 2014, and nine did in 2013. The most all-time national heat records held by any year is nineteen in 2010. Most nations do not maintain official databases of extreme temperature records, so the national temperature records reported here are in many cases not official. I use as my source for international weather records researcher Maximiliano Herrera, one of the world's top climatologists, who maintains a comprehensive list of extreme temperature records for every nation in the world on his website. If you reproduce this list of extremes, please cite Maximiliano Herrera as the primary source of the weather records. Wunderground's weather historian Christopher C. Burt maintains a database of these national heat and cold records for 235 nations and territories on's extremes page. Here are the all-time national or territorial heat and cold records set so far in 2015:

"Anguilla set its national heat record on September 12, when the mercury hit 33.8°C (92.8°F) at The Valley Airport.

The U.S. Virgin Islands set their national heat record on September 10, when the mercury hit 35.6°C (96°F) at Charlotte Amalie Airport. Note: the unofficial record listed by NOAA for the U.S. Virgin Islands is 99°F at the Charlotte Amalie Airport in 1988, 1994, and 1996. Mr. Herrera has researched the history of temperature measurements in the islands, and found that data taken at this airport was generally reliable after 1998 and before 1972. Between 1972 to 1998, the data was seriously flawed, with minimum temperatures up to 20°F from the real temperature.

Hong Kong set its national heat record on August 9, when the mercury hit 37.9°C (100.2°F) at Happy Valley.

Germany set a new national heat record of 40.3°C (104.5°F) twice this year: on July 5 and August 7, both at the Kitzingen station in Bavaria.

Vietnam tied its national heat record of 42.7°C (108.9°F) at Con Cuong on May 30.

Palau tied its national heat record of 34.4°C (94.0°F) at Koror Airport on May 14.

Venezuela set a new national heat record of 43.6°C (110.5°F) at Coro on April 29.

Laos tied its national heat record of 42.0°C (107.6°F) at Thakhek on April 20.

Ghana set a new national heat record of 43.3°C (109.9°F) at Navrongo on April 10. This is the third time this year Ghana has tied or set a new all-time heat record.

Cocos Islands (Australian territory) tied their all-time heat record with 32.8°C (91.0°F) on April 8.

Equatorial Guinea set a new national heat record of 35.5°C (95.9°F) at Bata on March 17.

Wallis and Futuna Territory (France) set a new territorial heat record with 35.5°C (95.9°F) on January 19 at Futuna Airport.

"Israel set a new national cold record of -14.2°C (6.4°F) at Merom Golan on January 10.

Cyprus set a new national cold record for an inhabited place of -10.7°C (12.7°F) at Prodromos on January 9 (and also a new cold record for an uninhabited place of -12.0°C at the new mountain station of Troodos Square; unofficial readings in the past were as low as -13°C, though).


"Antarctica set a new heat record for its mainland of 17.5°C (63.5°F) at Esperanza Base on March 24. Previous record: 17.4°C (63.3°F) at Marambio Base, set the previous day. The World Meteorological Organization (WMO) has appointed a committee to study this event and determine if this represents an official record for the continent. Note that this is a record for mainland Antarctica, not a territorial or continental record. 

The all-time maximum record for the continent and territory of Antarctica is 19.8°C (67.6°F) on January 30, 1982, in Signy Island, South Orkney, an island group located about 450 miles northeast of the tip of the Antarctic Peninsula, the northernmost portion of mainland Antarctica. 

Geologically, the South Orkney are on the Antarctic plate, and politically, they are part of Antarctica. This record was improperly listed as a territorial record for Antarctica in May's global summary.

"Switzerland had its highest reliably measured temperature on record in Geneva on July 7, when the mercury hit 103.5°F (39.7°C). The only higher temperature ever measured in the country was a 106.7°F (41.5°C) reading on August 11, 2003 at Grono. As reported at the Swiss news site, this old record was achieved "using an old measurement technique of weather huts, which generally recorded temperatures a few degrees higher than modern instruments." Weather records researcher Maximiliano Herrera agrees that this year's 39.7°C reading in Geneva is the highest reliably measured temperature ever in Switzerland, though the August 11, 2003 temperature at Grono was probably warmer (near 40°C), after correcting for the known problems with the site.

"Samoa was originally listed by Mr. Herrera as tying its national heat record with 36.5°C (97.7°F) on January 20 at Asau, but a subsequent review of the record revealed possible issues with the measurement equipment, so this record is dubious."
