The 1932 Atlantic hurricane season featured several powerful storms, including the Cuba hurricane, which remains the deadliest tropical cyclone in the history of Cuba and among the most intense to strike the island nation. It was a relatively active season, with fifteen known storms, six hurricanes, and four major hurricanes. However, tropical cyclones that did not approach populated areas or shipping lanes, especially if they were relatively weak and of short duration, may have remained undetected. Because technologies such as satellite monitoring were not available until the 1960s, historical data on tropical cyclones from this period are often not reliable. The Atlantic hurricane reanalysis project discovered four new tropical cyclones, all of which were tropical storms, that occurred during the year. Two storms attained Category 5 intensity, the first known occurrence in which multiple Category 5 hurricanes formed in the same year. The season's first cyclone developed on May 5, while the last remaining system transitioned into an extratropical cyclone by November 13.
The 1921 Atlantic hurricane season was an active hurricane season, with 12 tropical cyclones forming. Among them, seven became tropical storms, of which five strengthened into hurricanes. Furthermore, two of these strengthened into a major hurricane, Category 3 or higher on the modern-day Saffir–Simpson hurricane wind scale, the most since the 1917 season. The first system, a tropical depression, developed on June 1, while the last, a tropical storm, dissipated on November 25. Of note, three tropical cyclones co-existed with another during the season.
The 1893 Atlantic hurricane season featured the only known instance of more than one tropical cyclone causing at least 1,000 deaths in the United States. It was a fairly active season, with 12 tropical storms forming, 10 of which became hurricanes. Of those, five became major hurricanes. The season is considered hyper-active in terms of accumulated cyclone energy, achieving a total of 231 units, which remains the third-highest ever recorded in the Atlantic basin. Additionally, 1893 became one of two seasons on record to see four Atlantic hurricanes active simultaneously, along with 1998. In the absence of modern satellite and other remote-sensing technologies, only storms that affected populated land areas or encountered ships at sea were recorded, so the actual total could be higher. An undercount bias of zero to six tropical cyclones per year between 1851 and 1885 and zero to four per year between 1886 and 1910 has been estimated. The first system was initially observed on June 12 in the Bay of Campeche, while the twelfth and final storm transitioned into an extratropical cyclone on November 9 over the northwestern Atlantic.
The 1891 Atlantic hurricane season featured the most devastating tropical cyclone to impact the French overseas territory of Martinique since the early 19th century. Overall, ten tropical storms formed, seven of which became hurricanes. Of those, one became a major hurricane. However, in the absence of modern satellite and other remote-sensing technologies, only storms that affected populated land areas or encountered ships at sea were recorded, so the actual total could be higher. Therefore, an undercount bias of zero to six tropical cyclones per year between 1851 and 1885 and zero to four per year between 1886 and 1910 has been estimated. The first system was initially observed on July 3 in the Bay of Campeche, while the tenth and final storm was last noted offshore Atlantic Canada on November 6.
The 1889 Atlantic hurricane season was a relatively quiet season, with nine tropical storms and six hurricanes and no major hurricanes. However, due to scarce technology and the fact that only storms that affected populated land or ships were recorded, the actual total could be higher. An undercount bias of zero to six tropical cyclones per year between 1851 and 1885 and zero to four per year between 1886 and 1910 has been estimated.
The 1880 Atlantic hurricane season ran through the summer and fall of 1880. This is the period of each year when most tropical cyclones form in the Atlantic basin. In the 1880 Atlantic season there were two tropical storms, seven hurricanes, and two major hurricanes (Category 3+). However, in the absence of modern satellite and other remote-sensing technologies, only storms that affected populated land areas or encountered ships at sea were recorded, so the actual total could be higher. An undercount bias of zero to six tropical cyclones per year between 1851 and 1885 and zero to four per year between 1886 and 1910 has been estimated. Of the known 1880 cyclones, Hurricane Six was first documented in 1995 by José Fernández-Partagás and Henry Díaz. They also proposed large changes to the known tracks of several other storms for this year and 're-instated' Hurricane Ten to the database. A preliminary reanalysis by Michael Chenoweth, published in 2014, found thirteen storms, nine hurricanes, and four major hurricanes.
The 1885 Atlantic hurricane season ran through the summer and the first half of fall in 1885. This is the period of each year when most tropical cyclones form in the Atlantic basin. In 1885 there were two tropical storms and six hurricanes in the Atlantic basin. However, in the absence of modern satellite monitoring and remote-sensing technologies, only storms that affected populated land areas or encountered ships at sea were recorded, so the actual total could be higher. An undercount bias of zero to six tropical cyclones per year between 1851 and 1885 and zero to four per year between 1886 and 1910 has been estimated.
The 1926 Nassau hurricane also known as the San Liborio hurricane or Great Bahamas Hurricane of 1926, in Puerto Rico, was a destructive Category 4 hurricane that affected the Bahamas at peak intensity. Although it weakened considerably before its Florida landfall, it was one of the most severe storms to affect the Bahamian capital Nassau and the island of New Providence in several years until the 1928 Okeechobee hurricane, which occurred just two years later. The storm also delivered flooding rains and loss of crops to the southeastern United States and Florida.
The 1932 San Ciprián hurricane was one of the strongest tropical cyclones in the history of Puerto Rico. The center of the storm traversed the island on an east-to-west path in late September 1932, killing 272 people and inflicting at least $35 million in damage. Winds in San Juan, Puerto Rico, were estimated to have reached at least 120 mph (190 km/h), causing extensive destruction. The storm's origins can be traced back to at least September 25, 1932, when it was a tropical storm east of the Windward Islands. Moving west as a compact tropical cyclone, it rapidly intensified as it moved across the Virgin Islands the following day before ultimately making landfall on September 27 in Ceiba, Puerto Rico, at a peak intensity equivalent to that of a Category 4 hurricane on the modern Saffir–Simpson scale. The hurricane diminished for the remainder of its duration, leaving Puerto Rico and brushing the southern coast of Hispaniola. The cyclone passed near Jamaica on September 29 and moved ashore British Honduras on October 1 as a tropical storm, dissipating the next day over southeastern Mexico.
The 1851 Atlantic hurricane season was the first Atlantic hurricane season to be included in the official Atlantic tropical cyclone record. Six known tropical cyclones occurred during the season, the earliest of which formed on June 25 and the latest of which dissipated on October 19. These dates fall within the range of most Atlantic tropical cyclone activity. None of the cyclones existed simultaneously with another, while three of the storms only have a single point in their track known.
The 1852 Atlantic hurricane season was one of only three Atlantic hurricane seasons in which every known tropical cyclone attained hurricane status. Five tropical cyclones were reported during the season, which lasted from late August to the middle of October. These dates fall within the range of most Atlantic tropical cyclone activity, and none of the storms coexisted with another. Though there were officially five tropical cyclones in the season, hurricane scholar Michael Chenoweth assessed two of the cyclones as being the same storm. There may have been other unconfirmed tropical cyclones during the season, as meteorologist Christopher Landsea estimated that up to six storms were missed each year from the official database. This is unusual due to tropical cyclones being smaller than average, sparse ship reports, and relatively unpopulated coastlines at the time.
The 1891 Martinique hurricane, also known as Hurricane San Magín, was an intense major hurricane that struck the island of Martinique and caused massive damage. The third known hurricane and only major hurricane of 1891 Atlantic hurricane season, This cyclone was first sighted east of the Lesser Antilles on August 18 as a Category 2 hurricane on the present-day Saffir–Simpson scale. Intensification occurred as the storm moved northwestward, striking Martinique later that day as a Category 3 hurricane with maximum sustained winds of 125 mph (205 km/h). On August 20, the cyclone briefly turned northward over the Caribbean Sea and brushed the eastern Dominican Republic while re-emerging into the Atlantic Ocean. The storm then moved west-northwestward across the Bahamas before making landfall near Homestead, Florida, on August 24. Dissipation is estimated to have occurred on the following day after the cyclone reached the east-central Gulf of Mexico.
The 1881 Atlantic hurricane season featured a tropical cyclone that remains one of the deadliest in the history of the United States. Seven tropical storms are known to have developed, four of which strengthened into hurricanes, though none of those intensified into a major hurricane. However, in the absence of modern satellite and other remote-sensing technologies, only storms that affected populated land areas or encountered ships at sea were recorded, so the actual total could be higher. An undercount bias of zero to six tropical cyclones per year between 1851 and 1885 and zero to four per year between 1886 and 1910 has been estimated.
The 1854 Atlantic hurricane season featured five known tropical cyclones, three of which made landfall in the United States. At one time, another was believed to have existed near Galveston, Texas, in September. However, HURDAT – the official Atlantic hurricane database – now excludes this system. The first system, Hurricane One, was initially observed on June 25. The final storm, Hurricane Five, was last observed on October 22. These dates fall within the period with the most tropical cyclone activity in the Atlantic. No tropical cyclones during this season existed simultaneously. One tropical cyclone has a single known point in its track due to a sparsity of data.
The 1878 Atlantic hurricane season lasted from the summer through much of the fall. Records show that 1878 featured a relatively active hurricane season. A total of twelve storms were observed during the year. There were twelve tropical storms, eight hurricanes and two major 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 were recorded, so the actual total could be higher. An undercount bias of zero to six tropical cyclones per year between 1851 and 1885 and zero to four per year between 1886 and 1910 has been estimated. Of the known 1878 cyclones, both Hurricane Three and Hurricane Four were first documented in 1995 by Jose Fernandez-Partagas and Henry Diaz, who also proposed large changes to the known tracks of Hurricanes Two, Seven and Eight. Further analysis from 2000 onwards extended the duration of Hurricane Three by one day and identified major track changes for Hurricane Five.
The 1876 Atlantic hurricane season featured the first hurricane landfall in North Carolina since 1861. Overall, the season was relatively quiet, with five tropical storms developing. Four of these became a hurricane, of which two intensified into major hurricanes. However, due to the absence of remote-sensing satellite and other technology, only storms that affected populated land areas or encountered ships at sea were recorded; therefore, the actual total could be higher. An undercount bias of zero to six tropical cyclones per year between 1851 and 1885 and zero to four per year between 1886 and 1910 has been estimated.
The 1871 Atlantic hurricane season lasted from mid-summer to late-fall. Records show that 1871 featured two tropical storms, four hurricanes and two major 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 were recorded, so the actual total could be higher. According to a study in 2004, an undercount bias of zero to six tropical cyclones per year between 1851 and 1885 and zero to four per year between 1886 and 1910 is possible. A later study in 2008 estimated that eight or more storms may have been missed prior to 1878.
The San Felipe Hurricane was the second tropical cyclone of the 1876 Atlantic hurricane season. The storm was first observed east of the Leeward Islands on September 12, later intensifying to a Category 3 hurricane on the modern-day Saffir–Simpson scale while approaching Puerto Rico. In the upcoming days, the storm would make landfall on Hispaniola and Cuba, while also at hurricane intensity. Weakening to a tropical storm, it crossed the island until emerging over central Cuba, and passing just east of Florida. The storm re-intensified into a hurricane and struck near Wilmington, North Carolina, as Category 1 hurricane. Continuing inland, the San Felipe Hurricane gradually weakened over the United States, reaching near Cape Cod before dissipation on September 19.
The 1867 Atlantic hurricane season lasted from mid-summer to late-fall. A total of nine known tropical systems developed during the season, with the earliest forming on June 21, and the last dissipating on October 31. On two occasions during the season, two tropical cyclones simultaneously existed with one another; the first time on August 2, and the second on October 9. Records show that 1867 featured two tropical storms, six hurricanes and one major hurricane. However, in the absence of modern satellite and other remote-sensing technologies, only storms that affected populated land areas or encountered ships at sea were recorded, so the actual total could be higher. An undercount bias of zero to six tropical cyclones per year between 1851 and 1885 and zero to four per year between 1886 and 1910 has been estimated. Of the known 1867 cyclones Hurricanes Three, Four and Six plus Tropical Cyclones Five and Eight were first documented in 1995 by Jose Fernandez-Partagas and Henry Diaz. Hurricane One was first identified in 2003 by Cary Mock.
The 1855 Atlantic hurricane season featured tropical cyclone landfalls in the Gulf Coast of the United States, the Greater Antilles, and Mexico, but none along the East Coast of the United States. It was inactive, with only five known tropical cyclones. Another tropical storm was believed to have existed offshore Atlantic Canada in late August and early September, but HURDAT – the official Atlantic hurricane database – now excludes this system. The first known system was initially observed on August 5, while the final known storm was last noted on September 17. These dates fall within the period with the most tropical cyclone activity in the Atlantic. At one point during the season, two tropical cyclones existed simultaneously. Two of the cyclones only have a single known point in their tracks due to a sparsity of data.
