1921 Global Tropical Cyclones Outside the Northwest Pacific

Total entries in the 1921 database 12 12 tropical cyclones outside the Northwest Pacific in the South Pacific. For Northwest Pacific typhoons, see 1921 Typhoon .

Data reliability:
● ReliableWeather satellites monitored these systems throughout, resulting in relatively accurate tracks and intensities (Atlantic and Eastern Pacific from 1966; other basins from 1980)
● Generally reliableAircraft entered typhoons for direct measurements, but satellites were not yet widespread: tracks are generally accurate, while intensities may be biased and weaker cyclones may be missing (from 1950 until satellite coverage became widespread)
● Inferred dataWith no satellites or aircraft that year, intensities were retrospectively estimated from records from ships and coastal weather stations (before 1950)
● Track onlyOnly approximate positions are available, with no wind speed or pressure records, so they are excluded from intensity rankings (mostly early records from the Indian Ocean and Southern Hemisphere)
