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 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 1884 Atlantic hurricane season was one of only three Atlantic hurricane seasons, along with 1852 and 1858, in which every known tropical cyclone attained hurricane status. Overall, four tropical cyclones developed, three of which made landfall. The first system was initially observed over the northwestern Atlantic Ocean on September 1. It struck Newfoundland the following day, but impact there is unknown. On September 3, the next hurricane developed, though it did not affect land in its duration. The third hurricane struck Georgia, accompanied by damaging waves in north Florida.
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 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. Four seasons have had more storms: 1933 (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 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 1883 Atlantic hurricane season ran through the summer and the first half of fall in 1883. This is the period of each year when most tropical cyclones form in the Atlantic basin. In the 1883 Atlantic season there was one tropical storm, one Category 1 hurricane, and two major hurricanes. 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 1882 Atlantic hurricane season ran through the summer and early fall of 1882. This is the period of each year when most tropical cyclones form in the Atlantic basin. In the 1882 Atlantic season there were two tropical storms, two Category 1 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 1882 cyclones, Hurricane One and Hurricane Five were both first documented in 1996 by Jose Fernandez-Partagas and Henry Diaz, while Tropical Storm Three was first recognised in 1997. Partagas and Diaz also proposed large changes to the known track of Hurricane Two while further re-analysis, in 2000, led to the peak strengths of both Hurricane Two and Hurricane Six being increased. In 2011 the third storm of the year was downgraded from a hurricane to a tropical storm.
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, but 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 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 1877 Atlantic hurricane season lasted from mid-summer to late-fall. Records show that in 1877 there were eight cyclones, of which five were tropical storms and three were hurricanes, one of which 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. 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 1875 Atlantic hurricane season featured three landfalling tropical cyclones. 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 has been estimated. There were five recorded hurricanes and one major hurricane – Category 3 or higher on the modern-day Saffir–Simpson scale.
The 1874 Atlantic hurricane season was a relatively inactive one, in which seven tropical cyclones developed. Four storms intensified into hurricanes, but none attained major hurricane status. 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 1873 Atlantic hurricane season was quiet, with only two tropical storms and three hurricanes, two of which were major hurricanes, being recorded. 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 cyclones, large alterations were made to the tracks of Hurricane Two and Hurricane Five in 1995 by Jose Fernandez-Partagas and Henry Diaz, who also proposed smaller changes to the known track of Hurricane Three. All of the tropical cyclones, other than Hurricane Two, made landfall in Florida.
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.
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.
