- The 1857 Atlantic hurricane season was the earliest season documented by HURDAT – the official 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 Jose Fernandez-Partagas and Henry 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 first storm was tracked beginning on June 30 offshore North Carolina. It moved eastward and was last noted on the following day. However, no tropical cyclones were reported in the remainder of July or August. Activity resumed when another tropical storm was located southeast of the Bahamas on September 6. It intensified into a hurricane before making landfall in North Carolina and was last noted over the north Atlantic Ocean on September 17. The SS Central America sank offshore, drowning 424 passengers and crew members. Another hurricane may have existed east of South Carolina between September 22 and October 26, though little information is available. The final documented tropical cyclone was initially observed east of Lesser Antilles on September 24. It traversed the Caribbean Sea and the Gulf of Mexico, striking the Yucatán Peninsula and later Port Isabel, Texas. The storm dissipated on September 30. In Texas, damage was reported in several towns near the mouth of the Rio Grande River. The season's activity was reflected with a low accumulated cyclone energy (ACE) rating of 43. ACE is, broadly speaking, a measure of the power of the hurricane multiplied by the length of time it existed, so storms that last a long time, as well as particularly strong hurricanes, have high ACEs. It is only calculated at six-hour increments in which tropical and subtropical systems are either at or above sustained wind speeds of 39 mph (63 km/h), which is the threshold for tropical storm intensity.

- 1857年大西洋飓风季是美国国家飓风中心中记载的第一个没有形成大型飓风的大西洋飓风季，全季一共只形成四个热带气旋，其中三个达到飓风强度。不过，考虑到当时缺乏包括气象卫星在内的现代观测手段，基本上只有那些在海上遇到船只或是吹袭有人类居住陆地的风暴才有文献记载，所以实际形成的热带气旋数可能更高。气象学家（Christopher W. Landsea）估计，1851至1885年间实际形成的风暴数量可能比数据库中要多零到六场。此外，气象学家何塞·费尔南德斯-帕塔加斯（Jose Fernandez-Partagas）和亨利·迪亚兹（Henry Diaz）的文献还认为德克萨斯州卡梅伦县附近曾有第五个热带气旋存在，但由于这场风暴很可能与第四个热带气旋是同一天气系统，因此大西洋飓风数据库没有收录。 本季首场风暴于6月30日开始在北卡罗莱纳州近海出现，然后在向东移动期间于次日失去踪影。接下来两个月里，整个大西洋盆地都没有观测到热带气旋，直至9月6日才在巴哈马东南方向发现另一场热带风暴。这场风暴增强成飓风，然后登陆北卡罗莱纳州，最终于9月17日在北大西洋上空失去踪影。飓风导致“”在海上沉没，船上424人和三万磅黄金长眠大海，进而引发严重的经济危机。9月22至26日间，南卡罗莱纳州以东海域可能有另一场飓风存在，但相关信息很少。9月24日，小安的列斯群岛以东洋面发现另一个热带气旋，经过加勒比海和墨西哥湾吹袭尤卡坦半岛，之后又袭击德克萨斯州伊莎贝尔港，最终于9月30日消散。德克萨斯州格兰德河河口附近多个城镇受到破坏，但损失数额缺乏统计。 这年飓风季低迷的活跃程度还经累积气旋能量指数反映出来，数值仅有43。大致来说，气旋能量指数通过飓风强度和持续时间计算，强度越高、持续时间越长的风暴，其指数也相应越高。只有在热带天气系统风速达到或超过每小时63公里（34节）或热带风暴强度时才会计算该指数，并纳入全面的气象公告，并且亚热带气旋的指数不会计入累积数值。 (zh)
