World Temperature Records Explained: Highest and Lowest Temperatures Ever Recorded

Quick Answer: What Are the Hottest and Coldest Temperatures Ever Recorded?

The most widely cited official global temperature extremes are:

Official Air Temperature vs Surface Temperature, Heat Index and Wind Chill

“Hottest ever” and “coldest ever” headlines often mix different measurements.
Official world temperature records usually refer to air temperature
measured at a weather station under standardized conditions.

Highest Temperatures Ever Recorded by Continent and Region

The table below summarizes major officially cited high-temperature records by continent,
WMO region, and polar region. Some historical records are old and remain more verification-sensitive
than modern automated station records.

Lowest Temperatures Ever Recorded by Continent and Region

The coldest official air temperatures occur in Antarctica’s interior, where altitude,
polar night, dry air, and radiational cooling combine to produce extreme lows.
Siberia, Greenland, Canada, and high mountain basins also produce famous cold records.

Death Valley: The Hottest Temperature Ever Recorded on Earth

Furnace Creek in Death Valley, California, is the most famous heat-record location on Earth.
Its widely cited 56.7°C / 134°F reading from July 10, 1913 is commonly listed
as the highest official air temperature ever recorded.

Why Death Valley Gets So Hot

• Below-sea-level basin: Furnace Creek sits in a deep desert valley.
• Surrounding mountains: Air can descend, compress, and warm.
• Clear skies: Strong solar heating dominates summer days.
• Dry desert air: Low humidity allows extreme daytime heating.
• Hot ground surfaces: Rock and desert soils radiate intense heat near the surface.

Vostok Station: The Coldest Temperature Ever Recorded on Earth

Vostok Station in Antarctica recorded -89.2°C / -128.6°F on July 21, 1983.
This is the benchmark for the lowest official station-measured air temperature on Earth.

Why Vostok Gets So Cold

• Antarctic plateau elevation: High altitude helps create extreme cold.
• Polar night: Long darkness allows sustained radiational cooling.
• Very dry air: Less water vapor means less nighttime heat retention.
• Snow and ice surface: High reflectivity and strong cooling reinforce low temperatures.
• Isolation from ocean moderation: The interior ice sheet is far from warming marine influence.

Satellite studies have detected even colder surface skin temperatures in parts of Antarctica,
but those are not the same as official station-measured air-temperature records.

Antarctica Temperature Records

Antarctica holds both the world’s coldest official air-temperature record and several
important warm-temperature records for the Antarctic region, mainland, and plateau.

Verkhoyansk and Oymyakon: Famous Siberian Temperature Records

Verkhoyansk and Oymyakon are two of the most famous cold places on Earth.
Both are associated with extreme Siberian winter temperatures near
-67.8°C / -90°F, making them key benchmarks for inhabited-place cold.

Why Siberia Produces Extreme Cold

• Continental interior: Far from ocean moderation.
• Long winter nights: Extended radiational cooling.
• Snow cover: High reflectivity and strong surface cooling.
• Cold pooling: Dense air settles in valleys and basins.
• Persistent winter high pressure: Stable cold air can remain trapped for days or weeks.

Verkhoyansk is also famous for the opposite reason: it recorded a notable
38.0°C / 100.4°F Arctic Circle heat extreme in June 2020.
Few places symbolize Earth’s temperature range better than Siberia.

National Temperature Records

A national temperature record is the highest or lowest official temperature measured
within a country. These records are often checked by national weather agencies and,
in important cases, reviewed internationally.

Examples of famous national temperature records:

• United States: Death Valley’s 56.7°C heat benchmark.
• Canada: Lytton’s 49.6°C record during the 2021 Pacific Northwest heat dome.
• United Kingdom: the first official reading above 40°C in 2022.
• Russia: Siberian cold benchmarks at Verkhoyansk and Oymyakon.
• Australia: Oodnadatta’s 50.7°C heat record and Charlotte Pass cold benchmark.
• Italy: Sicily’s 48.8°C European continental heat record.

Hottest Countries in the World: Record Heat vs Average Heat

“Hottest country” can mean several things. A country may have the highest recorded
temperature, the hottest average annual climate, the hottest summer climate,
or the most extreme inhabited heat.

Countries often associated with extreme heat records include:

• United States — Death Valley, the classic global heat benchmark.
• Kuwait — Mitribah’s modern extreme heat record.
• Pakistan — Turbat’s extreme pre-monsoon heat.
• Tunisia — Kebili’s historic African heat record.
• Australia — Oodnadatta and widespread desert heat.
• Iran, Iraq, Saudi Arabia and Oman — extreme heat-prone regions with frequent severe summer temperatures.

Coldest Countries in the World: Record Cold vs Average Cold

“Coldest country” also depends on definition. Antarctica has the coldest measured
air temperature on Earth, but it is not a country. Among countries and inhabited regions,
Russia, Canada, Greenland/Denmark, Mongolia, Kazakhstan, and Nordic countries are frequently
associated with extreme cold.

Places often associated with extreme cold records include:

• Antarctica — Vostok Station, the coldest official air temperature on Earth.
• Russia — Verkhoyansk and Oymyakon, famous Siberian cold benchmarks.
• Canada — Snag, Yukon, one of North America’s most famous cold records.
• Greenland — ice-sheet extremes such as Klinck AWS.
• Mongolia and Kazakhstan — severe continental winter climates.
• Norway, Sweden and Finland — Arctic and subarctic cold extremes.

Temperature Record Maps

Temperature records are easier to understand visually. This page is designed to support
two evergreen map blocks: one for highest official temperatures by continent and one for
lowest official temperatures by continent and polar region.

Map note: Use these maps as visual summaries. The tables above remain the reference layer
for exact record values, dates, and locations.

Disputed and Rejected Temperature Records

Some extreme temperature claims are accepted, some are still debated, and some have been
rejected after review. This is especially true for very old records measured before modern
station metadata, instrument standards, and quality-control systems.

Why a record may be rejected or disputed:

• Instrument was not properly shielded or calibrated.
• Station exposure was affected by walls, pavement, roofs, engines, or artificial heat sources.
• Observation time or metadata was unclear.
• The value was inconsistent with nearby stations.
• The reported number did not fit the larger weather pattern.
• Historical documentation was incomplete.
