The 1912 Atlantic hurricane season was an average hurricane season that featured the first recorded November major hurricane. There were eleven tropical cyclones, seven of which became tropical storms; four of those strengthened into hurricanes, and one reached major hurricane intensity. The season's first cyclone developed on April 4, while the final dissipated on November 21. The season's most intense and most devastating tropical cyclone was the final storm, known as the Jamaica hurricane. It produced heavy rainfall on Jamaica, leading to at least 100 fatalities and about $1.5 million (1912 USD) in damage. The storm was also blamed for five deaths in Cuba.
The 1909 Atlantic hurricane season was an average Atlantic hurricane season. The season produced thirteen tropical cyclones, twelve of which became tropical storms; six became hurricanes, and four of those strengthened into major hurricanes. The season's first storm developed on June 15 while the last storm transitioned into an extratropical cyclone on November 14. The most notable storm during the season formed in late August, while east of the Lesser Antilles. The hurricane devastated the Lesser Antilles, the Greater Antilles, and Mexico, leaving around 4,000 fatalities and more than $50 million (1909 USD) in damage.
The 1907 Atlantic hurricane season was a very inactive hurricane season. Only five tropical storms formed, and none of them reaching hurricane strength. This season is one of only two that did not produce any hurricanes. Of the season's storms, three made landfall, all of them on the Gulf Coast of the United States. The first storm of the season formed on June 24, while the final dissipated on November 12. Damage from the storms were minimal, and no deaths were reported. Due to the lack of modern technology, including satellite imagery, information is often sparse, and four additional systems could have formed during the season. A documentation for four possible storms during the season exists, although it has not been proven that these systems were fully tropical.
The 1906 Atlantic hurricane season was an average season. It featured twelve tropical cyclones, eleven of which became storms, six became hurricanes and three became major hurricanes. The first storm of the season, a tropical storm in the northern Caribbean, formed on June 8; although it struck the United States, no major impacts were recorded. July saw a period of inactivity, with no known storms. However, in August, the streak of inactivity ended with two storms, including a powerful hurricane. September brought three storms, including a deadly hurricane, with catastrophic impacts in Pensacola and Mobile. October included three storms, with a powerful hurricane that killed over 200 people. The final storm of the season impacted Cuba in early November and dissipated on November 9. The season was quite deadly, with at least with 381 total recorded deaths.
The 1904 Atlantic hurricane season featured no tropical cyclones during the months of July and August. The season's first cyclone was initially observed in the southwestern Caribbean on June 10. After this storm dissipated on June 14, the next was not detected until September 8. The sixth and final system transitioned into an extratropical cyclone offshore South Carolina on November 4. Two of the six tropical cyclones existed simultaneously.
The 1901 Atlantic hurricane season was the most active season without a major hurricane – tropical cyclones that reach at least Category 3 on the Saffir–Simpson hurricane wind scale – until 2013. The first system was initially observed in the northeastern Caribbean on June 11. The fourteenth and final system transitioned into an extratropical cyclone near Bermuda on November 5. These dates fall within the period with the most tropical cyclone activity in the Atlantic. Eight of the fourteen tropical cyclones existed simultaneously.
The 1899 Atlantic hurricane season featured the longest-lasting tropical cyclone in the Atlantic basin on record. There were nine tropical storms, of which five became hurricanes. Two of those strengthened into major hurricanes, which are Category 3 or higher on the modern day Saffir–Simpson hurricane wind scale. The first system was initially observed in the northeastern Gulf of Mexico on June 26. The tenth and final system dissipated near Bermuda on November 10. These dates fall within the period with the most tropical cyclone activity in the Atlantic. In post-season analysis, two tropical cyclones that existed in October were added to HURDAT – the official Atlantic hurricane database. At one point during the season, September 3 through the following day, a set of three tropical cyclones existed simultaneously.
The 1898 Atlantic hurricane season ran through the summer and the first half of fall in 1898. The season was fairly active, with 11 storms forming, five of which became hurricanes.
The 1897 Atlantic hurricane season was an inactive season, featuring only six known tropical cyclones, four of which made landfall. There were three hurricanes, none of which strengthened into major hurricanes, which are Category 3 or higher on the modern-day Saffir–Simpson hurricane wind scale. The first system was initially observed south of Cape Verde on August 31, an unusually late date. The storm was the strongest of the season, peaking as a Category 2 hurricane with winds of 100 mph (155 km/h). While located well north of the Azores, rough seas by the storm sunk a ship, killing all 45 crewmen. A second storm was first spotted in the Straits of Florida on September 10. It strengthened into a hurricane and tracked northwestward across the Gulf of Mexico, striking Louisiana shortly before dissipating on September 13. This storm caused 29 deaths and $150,000 (1897 USD) in damage.
The 1894 Atlantic hurricane season ran through the summer and the first half of fall in 1894. The 1894 season was a fairly inactive one, with seven storms forming, five of which became hurricanes.
The 1890 Atlantic hurricane season was among the least active Atlantic hurricane seasons on record. The first tropical cyclone of the season was initially observed on May 27 and the last storm, Hurricane Four, dissipated over Central America on November 1. These dates fall within the period with the most tropical cyclone activity in the Atlantic. The first storm moved slowly north-northwestward, bringing heavy rains and extensive flooding to Cuba, which caused at least three fatalities and at least $1 million (1890 USD) in damage. It dissipated in the Gulf of Mexico on May 29. Tropical cyclogenesis went dormant for nearly two and a half months, until another system was observed near the Windward Islands on August 18. It traversed the Caribbean Sea and Gulf of Mexico, grazing the Yucatan Peninsula and making landfall in Louisiana before dissipating on August 28. Impact from the storm was minimal.
The 1891 Atlantic hurricane season began during the summer and ran through the late fall of 1891. The season had ten tropical cyclones. Seven of these became hurricanes; one becoming a major Category 3 hurricane.
The 1887 Atlantic hurricane season was the most active Atlantic hurricane season on record at the time in terms of number of known tropical storms formed, with 19. This total has since been equaled by 1995, 2010, 2011, and 2012. Five seasons have had more storms: 1933 and 2023 (20), 2021 (21), 2005 (28), and 2020 (30). The 1887 season featured five off-season storms, with tropical activity occurring as early as May, and as late as December. It is also worthy of note that the volume of recorded activity was documented largely without the benefit of modern technology. Tropical cyclones during this era 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 may not be comprehensive. 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 1887 cyclones, Tropical Storm One and Tropical Storm Three were first documented in 1996 by Jose Fernandez-Partagas and Henry Diaz. They also proposed large alterations to the known tracks of several of the other 1887 storms. Later re-analysis led to the known duration of Hurricane Six, and also that of Hurricane Fifteen, being increased.
The 1886 Atlantic hurricane season ran through the early summer and the first half of fall in 1886. This is the period of each year when most tropical cyclones form in the Atlantic basin. It was a very active year, with ten hurricanes, six of which struck the United States, an event that would not occur again until 1985 and 2020. Four hurricanes became 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 are known, 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 1886 cyclones, Hurricane Seven and Tropical Storm Eleven were first documented in 1996 by Jose Fernandez-Partagas and Henry Diaz. They also proposed large alterations to the known tracks of several other 1886 storms.
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 1917 Nueva Gerona hurricane was the most intense tropical cyclone to strike the Florida Panhandle until Hurricane Opal in 1995. The eighth tropical cyclone and fourth tropical storm of the season, this system was identified as a tropical storm east of the Lesser Antilles on September 20. After crossing the Lesser Antilles, the system entered the Caribbean Sea and achieved hurricane intensity on September 21. After becoming a Category 2 hurricane, the storm struck the northern coast of Jamaica on September 23. Early on September 25, the cyclone reached Category 4 status and attained maximum sustained winds of 150 mph (240 km/h) soon thereafter. Later that day, the hurricane made landfall in eastern Pinar del Río Province, Cuba. The system entered the Gulf of Mexico shortly thereafter and weakened slightly. Recurving to the northeast, the hurricane briefly threatened Louisiana before turning toward Florida. Early on September 29, the hurricane made landfall near Fort Walton Beach, Florida, with winds of 115 mph (185 km/h). Once over land, the cyclone rapidly weakened and transitioned into an extratropical cyclone before dissipating on September 30.
The 1879 Atlantic hurricane season ran from the summer to near the end of autumn in 1879. In 1879 there were 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. 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 1879 cyclones, Hurricane One were first documented in 1995 by Jose Fernandez-Partagas and Henry Diaz. They also proposed large changes to the known tracks of Hurricanes Two, Three, Seven and Eight. Later one storm was deemed not to be a tropical cyclone at all and was dropped from the database.
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 1863 Atlantic hurricane season featured five landfalling tropical cyclones. 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 has been estimated. There were seven recorded hurricanes and no major hurricanes, which are Category 3 or higher on the modern day Saffir–Simpson scale. Of the known 1863 cyclones, seven were first documented in 1995 by José Fernández-Partagás and Henry Diaz, while the ninth tropical storm was first documented in 2003. These changes were largely adopted by the National Oceanic and Atmospheric Administration's Atlantic hurricane reanalysis in their updates to the Atlantic hurricane database (HURDAT), with some adjustments.
The 1856 Atlantic hurricane season featured six tropical cyclones, five of which made landfall. The first system, Hurricane One, was first observed in the Gulf of Mexico on August 9. The final storm, Hurricane Six, was last observed on September 22. These dates fall within the period with the most tropical cyclone activity in the Atlantic. Only two tropical cyclones during the season existed simultaneously. One of the cyclones has only a single known point in its track due to a sparsity of data. Operationally, another tropical cyclone was believed to have existed in the Wilmington, North Carolina area in September, but HURDAT – the official Atlantic hurricane database – excludes this system. Another tropical cyclone that existed over the Northeastern United States in mid-August was later added to HURDAT.
