List of Atlantic hurricanes in the 18th century

Notable storms and documented impacts

• 1715 Spanish treasure fleet hurricane: One of the most famous wrecking storms of the era, recorded in Spanish and English sources for its destruction of ships off the Florida coast and consequent loss of treasure and lives. Documentation comes from survivors' accounts, salvage records and colonial correspondence.
• Great Hurricane of 1780: Widely recorded across the Caribbean as an exceptionally severe and deadly storm. Contemporary colonial and naval reports describe widespread destruction on several islands and heavy losses to shipping. It is regarded by historians as among the deadliest Atlantic hurricanes in the pre‑instrumental record.
• Regional landfalls and shipping losses: Throughout the century, a series of storms are documented striking the Lesser Antilles, Hispaniola, Cuba, the Bahamas and the eastern seaboard of North America. Many entries in 18th‑century lists derive from port damage reports, plantation records and insurance claims that identify the timing and area affected even when precise tracks are unknown.

Because official naming and consistent intensity scales did not exist, historians and meteorologists rely on qualitative descriptions: ship damage, reported barometric readings where available, storm surge and flooding accounts, and the spatial distribution of reports. Modern investigators also use geological and ecological proxies—overwash deposits in coastal sediment, tree‑ring stress signals, and coral records—to extend and corroborate documentary evidence. These interdisciplinary approaches allow reconstruction of storm frequency and relative intensity trends across the century, though absolute counts remain conservative compared with the actual number of storms that likely occurred.

Lists of 18th‑century Atlantic hurricanes therefore serve several purposes: they preserve primary documentary evidence of destructive events, provide data for long‑term climate and impact studies, and illuminate how societies of the period experienced and responded to extreme weather. For readers seeking compiled year‑by‑year listings, season summaries, or deeper technical discussion of reconstruction methods, consult the general season overviews and linked resources above and in specialist compilations that synthesize archival material and paleoclimate findings.

Researchers and interested readers should expect ongoing refinements as new documents are discovered and as paleotempestology methods improve. The partial nature of the record means that 18th‑century lists are best used as working catalogs—valuable windows into past hazards but always subject to revision.

Atlantic hurricane seasons summaries and chronological compilations remain the practical entry points for navigating recorded storms of the 18th century; more specialized sources address methods for reconstructing events from sparse historical evidence.

Additional context and comparative material can be found in overviews of earlier and later centuries: Before 1600, the 1600s, and continuing season-by-season accounts archived in modern compilations and research articles.

For precise dates and localized impact reports within this century consult primary archival collections and annotated catalogs that cite original dispatches, newspapers and marine records—the foundation of all published 18th‑century hurricane lists.
