Hot desert climates (''BWh'') are typically found under the [[subtropical ridge]] in the lower middle latitudes or the [[subtropics]], often between 20° and 33° north and south latitudes. In these locations, stable descending air and high pressure aloft clear clouds and create hot, arid conditions with intense sunshine. Hot desert climates are found across vast areas of [[North Africa]], [[West Asia]], northwestern parts of the [[Indian Subcontinent]], southwestern Africa, interior Australia, the [[Southwestern United States]], northern [[Mexico]], sections of southeastern [[Spain]], the coast of [[Peru]] and [[Chile]] and parts of the Brazilian [[sertão]]. This makes hot deserts present in every continent except Antarctica.

At the time of high sun (summer), scorching, desiccating heat prevails. Hot-month average temperatures are normally between {{cvt|29|and|35|C}}, and midday readings of {{convert|43–46|C|F}} are common. The world's absolute heat records, over {{convert|50|C|F}}, are generally in the hot deserts, where the heat potential can be the highest on the planet. This includes the record of {{convert|56.7|C|F}} in [[Death Valley]], which is currently considered the [[highest temperature recorded on Earth]].<ref>{{Cite web |title=Weather - Death Valley National Park |website=U.S. National Park Service |url=https://www.nps.gov/deva/learn/nature/weather-and-climate.htm |access-date=2022-04-23 |language=en |archive-date=2020-10-13 |archive-url=https://web.archive.org/web/20201013021511/https://www.nps.gov/deva/learn/nature/weather-and-climate.htm |url-status=live }}</ref> Some deserts in the [[tropics]] consistently experience very high temperatures all year long, even during wintertime. These locations feature some of the highest annual average temperatures recorded on Earth, exceeding {{convert|30|C|F}}, up to nearly {{convert|35|C|F}} in [[Dallol, Ethiopia]]. This last feature is seen in sections of Africa and [[Arabia]]. During colder periods of the year, night-time temperatures can drop to freezing or below due to the exceptional radiation loss under the clear skies. However, temperatures rarely drop far below freezing under the hot subtype.

Hot desert climates can be found in the deserts of [[North Africa]] such as the wide [[Sahara Desert]], the [[Libyan Desert]] or the [[Nubian Desert]]; deserts of the [[Horn of Africa]] such as the [[Danakil Desert]] or the [[Grand Bara|Grand Bara Desert]]; deserts of [[Southern Africa]] such as the [[Namib Desert]] or the [[Kalahari Desert]]; deserts of [[West Asia]] such as the [[Arabian Desert]], or the [[Syrian Desert]]; deserts of [[South Asia]] such as [[Dasht-e Lut]] and [[Dasht-e Kavir]] of Iran or the [[Thar Desert]] of India and Pakistan; deserts of the United States and Mexico such as the [[Mojave Desert]], the [[Sonoran Desert]] or the [[Chihuahuan Desert]]; deserts of Australia such as the [[Simpson Desert]] or the [[Great Victoria Desert]] and many other regions. In [[Europe]], the hot desert climate can only be found on southeastern coast of [[Spain]] as well as small inland parts of southeastern, especially parts of the [[Tabernas Desert]].<ref>{{cite book |title=Atlas Climático Ibérico |trans-title=Iberian Climate Atlas |year=2011 |url=http://www.aemet.es/documentos/es/conocermas/recursos_en_linea/publicaciones_y_estudios/publicaciones/Atlas-climatologico/Atlas.pdf |doi=10.31978/784-11-002-5 |isbn=978-84-7837-079-5 |lang=es, pt, en |access-date=May 8, 2017|archive-date=November 25, 2020|archive-url=https://web.archive.org/web/20201125004016/http://www.aemet.es/documentos/es/conocermas/recursos_en_linea/publicaciones_y_estudios/publicaciones/Atlas-climatologico/Atlas.pdf|url-status=live}}</ref><ref name="ChazzaraBernabé_2022">{{Cite report |year=2022 |title=Evolucion de los climas de Koppen en España: 1951-2020 |url=https://www.aemet.es/documentos/es/conocermas/recursos_en_linea/publicaciones_y_estudios/publicaciones/NT_37_AEMET/NT_37_AEMET.pdf |access-date=2024-01-08 |website=[[Agencia Estatal de Meteorologia]] |archive-date=2024-02-13 |archive-url=https://web.archive.org/web/20240213184548/https://www.aemet.es/documentos/es/conocermas/recursos_en_linea/publicaciones_y_estudios/publicaciones/NT_37_AEMET/NT_37_AEMET.pdf |url-status=live |lang=es |first1=Andrés |last1=Chazarra Bernabé |first2=Belinda |last2=Lorenzo Mariño |first3=Ramiro |last3=Romero Fresneda |first4=José Vicente |last4=Moreno García |series=Nota técnica de AEMET |volume=37 |doi=10.31978/666-22-011-4}}</ref>

Hot deserts are lands of extremes: most of them are among the hottest, the driest, and the sunniest places on Earth because of nearly constant high pressure; the almost permanent removal of low-pressure systems, dynamic fronts, and atmospheric disturbances; sinking air motion; dry atmosphere near the surface and aloft; the exacerbated exposure to the sun where solar angles are always high makes this desert inhospitable to most species.
