Updated: • Part of Record Temperature Extremes Explained
Scope note: This page is about official record high temperatures. It does not fully explain heat-wave formation, heat-dome dynamics, wildfire impacts, or human heat stress. And keep in mind: large positive temperature anomalies do not automatically become record high temperatures.
TL;DR: Record High Temperatures
- Highest official air temperature: 56.7°C / 134°F at Furnace Creek, Death Valley, USA, on July 10, 1913.
- Modern verified extreme heat benchmark: 53.9°C at Mitribah, Kuwait, on July 21, 2016.
- European continental record: 48.8°C in Siracusa, Sicily, Italy, on August 11, 2021, confirmed by WMO.
- Arctic Circle heat record: 38.0°C in Verkhoyansk, Russia, on June 20, 2020, recognized by WMO.
- Official heat records mean measured air temperature, not land surface temperature, heat index, or “feels like” temperature.
- The hottest place on Earth depends on whether you mean highest measured temperature, hottest average climate, hottest city, or hottest inhabited place.
What Is a Record High Temperature?
A record high temperature is the highest officially measured air temperature
for a defined place, time period, and dataset. It may be a daily record, monthly record,
seasonal record, annual record, all-time station record, national record, continental record,
or world record.
“Record heat” is a broad headline phrase. “Record high temperature” is more precise:
it usually refers to a verified maximum air temperature measured at a weather station.
where it was measured, when, which category,
and whether it was officially verified.
Highest Temperature Ever Recorded on Earth
The most widely cited official highest air temperature ever recorded on Earth is
56.7°C / 134°F, measured at Furnace Creek, Death Valley, California,
on July 10, 1913. The WMO archive is the key reference for recognized
weather and climate extremes. :contentReference[oaicite:0]{index=0}
| Record | Temperature | Location | Date | Category |
|---|---|---|---|---|
| Highest official air temperature | 56.7°C / 134°F | Furnace Creek, Death Valley, California, USA | July 10, 1913 | World station air-temperature record |
Death Valley remains the classic global heat benchmark, but its 1913 reading is also one
of the most discussed historic records because very old extremes depend heavily on station
exposure, instrument quality, metadata, and documentation.
World Heat Records: Hottest Official Temperatures
The world’s hottest official air-temperature records are concentrated in deserts,
subtropical drylands, and heat-prone continental interiors. Extreme claims are carefully
reviewed because small siting or instrument errors can matter when records approach
the upper limits of measured air temperature.
| Rank / Category | Temperature | Location | Date | Record Context |
|---|---|---|---|---|
| World benchmark | 56.7°C / 134°F | Death Valley, California, USA | July 10, 1913 | Highest widely cited official air temperature |
| Modern verified extreme | 53.9°C | Mitribah, Kuwait | July 21, 2016 | WMO-evaluated major modern heat record |
| Modern verified extreme | 53.7°C | Turbat, Pakistan | May 28, 2017 | WMO-evaluated major modern heat record |
| Recent Death Valley readings | 54.4°C / 130°F | Death Valley, California, USA | August 16, 2020 and July 9, 2021 | Potential modern benchmark values under review context |
WMO has officially evaluated the Mitribah, Kuwait and Turbat, Pakistan extremes as among
the hottest temperatures recorded on Earth; WMO reported 53.9°C for Mitribah and 53.7°C
for Turbat in its evaluation context. :contentReference[oaicite:1]{index=1}
Highest Temperatures by Continent and Region
Continental heat records are useful because they separate regional extremes from the
single global benchmark. Many of these values are WMO-recognized or widely cited in
official summaries.
| Continent / Region | Temperature | Location | Date | Notes |
|---|---|---|---|---|
| North America | 56.7°C / 134°F | Furnace Creek, Death Valley, USA | July 10, 1913 | Global and North American benchmark |
| Africa | 55.0°C / 131°F | Kebili, Tunisia | July 7, 1931 | Historic African heat record |
| Asia | 53.9°C | Mitribah, Kuwait | July 21, 2016 | Highest WMO-recognized Asian temperature in modern evaluation |
| South America | 48.9°C / 120°F | Rivadavia, Argentina | December 11, 1905 | Historic continental benchmark |
| Europe | 48.8°C / 119.8°F | Siracusa, Sicily, Italy | August 11, 2021 | WMO-confirmed continental European record |
| Australia | 50.7°C / 123.3°F | Oodnadatta, South Australia | January 2, 1960 | Australian heat benchmark |
| Arctic Circle | 38.0°C / 100.4°F | Verkhoyansk, Russia | June 20, 2020 | WMO-recognized Arctic Circle record |
| Antarctic Region | 19.8°C / 67.6°F | Signy Research Station | January 30, 1982 | Antarctic region south of 60°S |
| Antarctic Mainland | 18.3°C / 64.9°F | Esperanza Station | February 6, 2020 | Antarctic mainland and nearby islands benchmark |
WMO confirmed the 48.8°C value recorded in Siracusa, Sicily, on August 11, 2021 as the
new continental European temperature record, and recognized Verkhoyansk’s 38.0°C
June 2020 reading as an Arctic Circle record. :contentReference[oaicite:2]{index=2}
National Heat Records
National record high temperatures are among the most searched heat records because they
become long-term reference points for countries: the hottest temperature in Canada,
the hottest temperature in the UK, the hottest temperature in Australia, or the hottest
temperature ever measured in Italy.
National record pages should track:
- Highest official national temperature
- Location and station name
- Date and time of observation
- Verification status
- Previous record
- Whether the value was preliminary, confirmed, disputed, or rejected
Old articles about “country breaks all-time heat record” should usually point here
or to the broader World Temperature Records Explained page.
Hottest Countries in the World
“Hottest country” can mean several different things. It may refer to the highest
temperature ever measured, the hottest average climate, the hottest summer conditions,
or the hottest inhabited regions.
Countries strongly associated with record heat include:
- United States — Death Valley holds the classic global heat benchmark.
- Kuwait — Mitribah recorded one of the hottest modern verified air temperatures.
- Pakistan — Turbat is a major modern extreme heat benchmark.
- Tunisia — Kebili is associated with Africa’s historic heat record.
- Australia — Oodnadatta and the interior deserts are famous for extreme heat.
- Italy — Sicily holds the WMO-confirmed continental European heat record.
- Iran, Iraq, Saudi Arabia and Oman — frequently experience severe summer heat.
For heat duration, human impacts, warnings, and multi-day extreme heat episodes, see
Heat Waves Explained.
Hottest Cities and Urban Heat Records
City heat records are especially important because people experience heat in built environments.
However, urban records must be interpreted carefully because official stations may be located
at airports, observatories, rooftops, parks, or suburban sites.
Urban heat records can refer to:
- All-time city record high
- Airport station record
- Downtown station record
- Record warm overnight minimum
- Longest run of days above a threshold
- Hottest month or summer in a city dataset
Street-level heat near asphalt, glass, traffic, and concrete can be much higher than
the official air temperature.
Hottest Months, Warmest Years and Global Heat Records
Not all heat records are single-station maximum temperatures. Some of the most important
heat records are monthly, seasonal, annual, or global-average records.
| Record Type | What It Measures | Why It Matters |
|---|---|---|
| Daily record high | Highest maximum temperature for one calendar date | Useful for local heat headlines |
| All-time station record | Highest temperature ever measured at one station | Major local or regional benchmark |
| Record warm night | Highest daily minimum temperature | Important for cities and heat stress |
| Hottest month | Warmest monthly average in a dataset | Shows persistence, not just one-day heat |
| Warmest year | Annual average temperature record | Important for climate context |
| Global-average record | Planetary temperature estimate from datasets or reanalysis | Different from station air-temperature records |
For record categories and datasets, see
Record Temperature Extremes Explained.
Why Record High Temperatures Occur
Record high temperatures happen when a location reaches or exceeds the upper end of its
historical temperature range. This page keeps the explanation short because the full mechanics
belong in the heat-wave and heat-dome pillars.
Common record-high temperature ingredients:
- Persistent high pressure that favors clear skies and sinking air.
- Subsidence warming, where sinking air compresses and heats.
- Dry soils that reduce evaporative cooling and increase surface heating.
- Hot air advection from deserts or continental interiors.
- Clear skies that maximize solar heating during the day.
- Urban heat storage, especially for record warm nights.
- Local geography, including basins, valleys, downslope winds, and desert terrain.

Heat Domes Explained.
For multi-day extreme heat events, see
Heat Waves Explained.
Recent Record Heat Events
Recent record heat events often involve national records, continental records, or record warm
months rather than just one station. This section is an evergreen sink for modern record heat
stories and should be updated when major records are officially confirmed.
2021 — Pacific Northwest and Canada record heat
The 2021 Pacific Northwest heat event produced extraordinary heat records, including
Canada’s all-time national high at Lytton. This event belongs here for measured records,
while the atmospheric setup belongs under heat domes.
2021 — Sicily sets new European continental heat record
Siracusa, Sicily recorded 48.8°C on August 11, 2021. WMO later confirmed it as the
new continental European temperature record. :contentReference[oaicite:3]{index=3}
2020 — Verkhoyansk Arctic Circle heat record
Verkhoyansk, Russia reached 38.0°C on June 20, 2020. WMO recognized this as a new
Arctic Circle temperature record. :contentReference[oaicite:4]{index=4}
2016–2017 — Kuwait and Pakistan extreme heat records
Mitribah, Kuwait and Turbat, Pakistan produced two of the hottest modern officially
evaluated air-temperature records. :contentReference[oaicite:5]{index=5}
Historic Record Heat Events
Some heat events become historical benchmarks because of their extreme readings,
geographic scale, duration, or long-term cultural memory.
- 1913 Death Valley: the famous 56.7°C global heat benchmark.
- 1931 Kebili, Tunisia: historic African extreme heat record.
- 1936 North American heat: Dust Bowl-era heat records and severe impacts.
- 1960 Oodnadatta, Australia: Australia’s classic extreme heat benchmark.
- 2003 Europe heat wave: historic heat event remembered for duration and impacts.
- 2021 Pacific Northwest heat: modern record-shattering heat event.
- 2021 Sicily: WMO-confirmed continental European record.
For the full timeline of benchmark heat and cold events, see
Historic Temperature Extremes Explained.
How Record High Temperatures Are Verified
Record high temperatures are checked carefully because extreme heat values can be distorted
by poor exposure, direct sun, nearby asphalt, sensor errors, or station metadata problems.
The WMO archive exists to provide a formal reference for evaluated global and regional
weather extremes. :contentReference[oaicite:6]{index=6}
Verification checks usually include:
- Instrument calibration
- Sensor shielding and ventilation
- Station height and exposure
- Nearby artificial heat sources
- Surface type around the station
- Observation time and metadata
- Comparison with nearby stations
- Consistency with the weather pattern

Temperature Record Verification Explained.
What Does Not Count as a Record High Temperature?
Many viral “hottest ever” claims are not official air-temperature records.
They may still be interesting, but they are different metrics.
| Claim | Why It Is Not an Official Record High Temperature |
|---|---|
| Car thermometer reading | Often affected by road heat, engine heat, sun exposure, and sensor placement |
| Land surface temperature | Measures ground or surface skin temperature, not air temperature |
| Heat index | Measures human heat stress from temperature and humidity |
| Direct-sun thermometer | Sunlight heats the instrument itself |
| Phone app “feels like” temperature | Usually an index or model estimate, not a station record |
| Rooftop or pavement reading | May reflect local surface heating rather than standardized air temperature |
FAQ: Record High Temperatures
What is the highest temperature ever recorded on Earth?
The most widely cited official air-temperature record is 56.7°C / 134°F,
measured at Furnace Creek in Death Valley, California, on July 10, 1913.
What is the hottest place on Earth?
Death Valley is the most famous hottest-place benchmark because it holds the widely cited
official highest air-temperature record. But “hottest place” can also mean hottest average
climate, hottest city, or hottest inhabited location.
What is the highest temperature ever recorded in Europe?
WMO confirmed 48.8°C in Siracusa, Sicily, Italy, on August 11, 2021 as the continental
European temperature record.
What is the highest temperature ever recorded in Asia?
Mitribah, Kuwait recorded 53.9°C on July 21, 2016, one of the highest modern officially
evaluated temperatures on Earth.
Is heat index a temperature record?
No. Heat index is a human heat-stress estimate based on air temperature and humidity.
It is not the same as an official air-temperature record.
Can a city street be hotter than the official record?
Yes. Asphalt, concrete, walls, roofs, traffic, and direct sun can make local surfaces
much hotter than the official air temperature measured at a weather station.
Why are some heat records disputed?
Heat records may be disputed because of poor station exposure, instrument uncertainty,
missing metadata, direct solar heating, nearby artificial heat sources, or inconsistency
with nearby observations.
What is the difference between record heat and a heat wave?
Record heat refers to a measured temperature record. A heat wave is a multi-day period
of unusually hot weather. A heat wave can produce record high temperatures, but the terms
are not identical.
