Hottest Temperatures Ever Recorded — By Country
About This Dataset
Hottest Temperatures Ever Recorded — By Country
The highest air temperatures ever officially recorded in each of the world's major countries, according to World Meteorological Organisation records. Death Valley in California holds the all-time global temperature record of 56.7°C (134°F) recorded on 10 July 1913 — though some scientists dispute the instrumentation used at that time.
Analysis
Aziziya (Libya) heads the table on 58, ahead of Death Valley (United States) (56.7) and Kebili (Tunisia) (55) in Record Temperature (°C) in 2021. 7.30 separates the highest figure (58) from the lowest (50.7) in Record Temperature (°C). First and second are separated by 1.30, so the leader sits inside the field rather than apart from it. Places 3 to 8 are close together, spanning 55 to 50.7 Record Temperature (°C).
Key Findings
🏆
Aziziya (Libya) leads in Record Temperature (°C) with 58 in 2021.

How the figures are calculated
- Values are shown as reported by the source. Nothing is rescaled, rebased or converted — the only changes are thousand separators and decimals shown to two places.
- Missing years are left empty rather than estimated — no interpolation, no carrying a previous year forward.
- Change is measured between the first and last year in which an entity actually reported a value, so a series that starts late is not penalised for the years before it existed.
- The compound annual rate is (last ÷ first)^(1 ÷ years) − 1, using those same two reported years.
- Entities are ranked highest-first on their value in 2021.
- An entity that reported nothing in the latest year is still listed — it follows the ranked entities in the table rather than being dropped.
