Temperature extremes are the highest and lowest temperatures recorded in specific locales. As extreme points, they provide a range of typical temperatures in that locale. Temperature is the physical property of a system which underlies the common notions of hot and cold; the material with the higher temperature is said to be hotter. ...

Only outdoor climactic temperatures are recorded; temperatures recorded inside forest fires, for example, would not be included. Additionally, only temperatures recorded four feet (1.2 metres) or higher above the ground, and in the shade, are admissible, as ground temperatures in many areas are much hotter than air temperatures. One inch above the ground, temperatures can exceed 90 degrees Celsius (194 °Fahrenheit) in the deserts. Fire in San Bernardino, California Mountains (image taken from the International Space Station) A wildfire, also known as a forest fire, vegetation fire, grass fire, or bushfire (in Australasia), is an uncontrolled fire in wildland often caused by lightning; other common causes are human carelessness and arson. ...

A degree Celsius (°C) is a unit of temperature named after the Swedish astronomer Anders Celsius (1701-1744), who first proposed a similar system in 1742. ... Fahrenheit is a temperature scale named after the German physicist Gabriel Fahrenheit (1686–1736), who proposed it in 1724. ...

Recorded temperature extremes are almost certainly not the highest and lowest climactic temperatures ever; weather records have only been kept for a few decades in some locales, and uninhabited locations are recorded rarely if ever. As well, many readings exist exceeding documented extremes but are disputed. For example, there are disputed claims of 60.0 °C (140 °F) readings in the Mexican deserts.
