The 1857 Atlantic hurricane season was an extremely inactive but deadly Atlantic hurricane season that and also had the earliest season documented by the Atlantic hurricane database to feature no major hurricanes. A total of four tropical cyclones were observed during the season, three of which strengthened into hurricanes. However, in the absence of modern satellite and other remote-sensing technologies, only storms that affected populated land areas or encountered ships at sea are known, so the actual total could be higher. An undercount bias of zero to six tropical cyclones per year between 1851 and 1885 has been estimated. Additionally, documentation by José Fernández-Partagás and Henry F. Diaz included a fifth tropical cyclone near Port Isabel, Texas; this storm has since been removed from HURDAT as it was likely the same system as the fourth tropical cyclone. The season had an accumulated cyclone energy (ACE) rating of 46.84. 4 storms, 3 hurricanes, 0 major hurricanes (Category 3+). Strongest: an unnamed storm (105 mph). Accumulated cyclone energy ≈ 47.
