Worst Cyclonic Storms Ever — Global Primer & Records

How far back do records go?

Systematic Atlantic best-track data curated by NOAA (HURDAT2) start in 1851, with earlier information from ship logs and colonial accounts. Global “best track” archives are unified in IBTrACS (NOAA), which merges agency datasets and extends to the 19th century, with reliable global coverage after the satellite era began in the late 1960s.

Hurricane vs. Typhoon vs. (Tropical) Cyclone

These are the same meteorological phenomenon—regional names differ by basin: “Hurricane” (Atlantic & Eastern North Pacific), “Typhoon” (Western North Pacific), and “(Tropical) Cyclone” (Indian Ocean & South Pacific). The World Meteorological Organization (WMO) uses “tropical cyclone” generically.

Saffir–Simpson Hurricane Wind Scale (SSHWS)

The SSHWS classifies storms by 1-minute sustained wind at 10 m height:

Category1-min sustained wind
Cat 174–95 mph (64–82 kt)
Cat 296–110 mph (83–95 kt)
Cat 3111–129 mph (96–112 kt)
Cat 4130–156 mph (113–136 kt)
Cat 5≥ 157 mph (≥ 137 kt)

Source: NOAA/NHC.

Why knots vs mph?

The U.S. (NHC/JTWC) reports 1-minute sustained winds, often in knots for operational marine use. Many WMO members (e.g., JMA) use 10-minute sustained winds. A common (approximate) conversion from 1-min to 10-min is ×0.88, but agency methods differ; always compare within the same averaging period.

What drives strong tropical cyclones?

Impacts: The SSHWS rates wind only. Most deaths and damage often come from storm surge and freshwater flooding.


Top Historical Storms (by basin)

Notes: Fatality and damage figures—especially before the satellite era—can vary by source; ranges are shown where appropriate. USD values are typically at-year estimates; U.S. costs use NOAA CPI-adjusted NCEI figures where available.
