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.
Because there were no modern satellite or other remote-sensing technologies, only cyclones that affected populated land areas or that encountered ships at sea are currently known, so the true total could be higher. For the years 1886 through 1910, an undercount bias of zero to four tropical cyclones per year has been estimated.[1]
The tracks of four of the ten cyclones were revised in 1996 by Jose Fernandez-Partagas.[2] Following re-analysis in 2003, two storms previously considered distinct are now regarded as a single system, Tropical Storm 8. A number of other storms from 1891 were considered for inclusion in the Atlantic hurricane database, HURDAT, but are currently excluded due to a lack of evidence of tropical storm intensity.

Ships reported a low-pressure area in the Gulf of Mexico northwest of Campeche beginning on July 3, which is believed to have been a tropical storm.[2] The storm moved northwestward and reached hurricane status by the following day, several hours before peaking with maximum sustained winds of 90 mph (150 km/h). Around 22:00 UTC on July 5, the hurricane made landfall near present-day Freeport, Texas. Upon the cyclone's landfall, the Atlantic hurricane reanalysis project estimated that it had a barometric pressure of 977abbr=onNaNabbr=on based on the pressure-wind relationship.[3] The hurricane curved north-northeastward and quickly weakened to a tropical storm by early on July 6. Weakening to a tropical depression late on the following day, the system dissipated on July 8 near the Alabama-Mississippi-Tennessee state line.
In Texas, storm surge flooded sections of Galveston,[4] while washing out some street car tracks and destroying part of the breakwater at the Beach Hotel. Winds and rain also left power outages in the city.[5] Tornadoes spawned by the hurricane in Louisiana demolished one hundred homes in Baton Rouge and caused two floors of the state penitentiary to collapse, killing ten prisoners.[2] Among the many other buildings damaged was the Louisiana Governor's Mansion, losing its roof and consequently being flooded.[6] Another tornado was reported in Madison, Mississippi, destroying several buildings and downing many telegraph wires.[7]

The official track for this storm begins on August 17 to the south of the Cabo Verde Islands, based on a path created by Charles Mitchell in 1924 and reconstructed by C. J. Neumann in 1993. Although the storm was not detected prior to August 26,[2] it likely moved west-northwestward and intensified into a hurricane on August 19. The cyclone gradually shifted to a more northwestward motion over the next several days, and on August 27, it passed just under 80abbr=onNaNabbr=on east of Bermuda. Barometric pressures on the island fell to 997mbar. This, as well as observations from the steamers Dunsmurry and La Touraine, led the Atlantic hurricane reanalysis project to conclude that the storm did not intensity beyond a minimal hurricane with winds of 75 mph (120 km/h).[3] Considered the worst cyclone to impact Bermuda since 1880, the hurricane downed brick walls, trees, and telegraph wires.[8] Early on August 29, the storm became extratropical about 220abbr=onNaNabbr=on south-southeast of Cape Sable Island, Nova Scotia.
Chenoweth proposed a tropical depression phase to the storm's earlier stages and a more southerly track, although the system instead turned northeastward after passing Bermuda and became extratropical near Newfoundland.

The Martinique Hurricane of 1891 or Hurricane San Magín of 1891
See main article: 1891 Martinique hurricane. A Category 2 hurricane with winds of 105 mph (170 km/h) was first seen at mid-day on August 18 about 100abbr=onNaNabbr=on east of Barbados. The hurricane tracked northwestward and intensified into a major Category 3 hurricane. Late on August 18, the cyclone struck Martinique at its peak intensity with sustained winds of 125 mph (205 km/h) and a minimum pressure of 961mbar. The storm weakened over the northeastern Caribbean and fell to Category 2 intensity early on August 20. Several hours later, the system turned northward and brushed the extreme eastern edge of the Dominican Republic with winds of 100 mph (155 km/h). Resuming its northwestward motion on August 21, the cyclone passed north of Grand Turk early the next day. The hurricane continued to weaken while traveling northwestward through the Bahamas and passed directly over Crooked Island. On August 23, a ridge of high pressure situated off the southeast coast of the United States prevented the storm, which had weakened to a Category 1 hurricane, from curving back to the north. Instead, the cyclone struck Florida near Homestead on August 24 and subsequently moved into the Gulf of Mexico, where it dissipated on August 25.
On Martinique, the storm destroyed houses, crops, and trees across the entire island. Fifty boats in harbors around Martinique were damaged or destroyed. At Ducos, only four homes remained following the storm, and at St. Pierre, at least 34 people lost their lives. At Fort de France, twenty people were killed. A military camp at Balata was destroyed, with a number of soldiers there sustaining injuries from airborne debris.[9] Property damage across the island reached approximately $10 million.[2] In total, the hurricane killed approximately 700 people on Martinique.[10] Puerto Rico observed heavy rainfall and hurricane-force wind gusts. The Humacao River overflowed, inundating the city. Waterways between Cabo Rojo and Hormigueros also exceeded their banks, flooding many low-lying areas and sweeping animals away.[2] The steamship Ozama reported hundreds of downed fruit trees and numerous damaged homes in the Dominican Republic.[11] The storm drowned three people on Grand Turk and damaged some small homes and vessels.[2] In South Florida, the cyclone also produced hurricane-force winds that blew boats ashore near present-day Cutler.

Based on a 1993 reanalysis by meteorologist C. J. Neumann,[2] the official Atlantic hurricane database begins the track of this system as a tropical storm approximately 260abbr=onNaNabbr=on northeast of the Leeward Islands on September 2. It moved northwestward for the next few days and intensified, reaching hurricane status on September 4, shortly before becoming a Category 2 hurricane that day. Peaking with maximum sustained winds of 100 mph (155 km/h), the hurricane turned northward on September 6 and then northeastward on September 7. By early the following day, the system made landfall near Canso, Nova Scotia, and later near Channel-Port aux Basques, Newfoundland, as a Category 1 hurricane at both locations. Late on September 8, while located east of Labrador, the storm transitioned into an extratropical cyclone, which dissipated near the southern tip of Greenland on September 10.
By September 7 the cyclone was off the coast of New England and was bringing heavy rain to that area. When the hurricane made landfall in Nova Scotia and Newfoundland on September 8, it destroyed a number of small vessels[2] but then quickly weakened and dissipated north of Newfoundland in the Labrador Sea on September 10. In Nova Scotia, the storm was compared to a hurricane in 1873.[12] Observed sustained winds reached 60mph, causing "great destruction to crops, shipping, and buildings", according to The Huddersfield Daily Chronicle. Damage to fruit crops totaled nearly $58,000. The storm also partially destroyed a drain elevator and several small bridges,[13] while about two-thirds of a larger railroad bridge linking Halifax and Dartmouth collapsed, causing more than $50,000 in damage.[12] Rough seas beached a few schooners and several Royal Nova Scotia Yacht Squadron vessels in the Halifax area, while hundreds of other small watercraft suffered some degree of damage. Farther east, several other vessels wrecked at Cape Breton Island.[12]

On September 16, the track for this storm begins near 19°N 47°W, over the open Atlantic well east of the Leeward Islands, based on a path constructed by Charles Mitchell in 1924.[2] Moving northwestward, the cyclone became a hurricane on September 19. Between late on September 21 and early on September 22, the hurricane passed about 45 mi (75 km) east of Bermuda. A barometric pressure of 980mbar was observed on the island, leading the Atlantic hurricane reanalysis project to estimate that the storm peaked as a Category 2 hurricane with winds of 100 mph (155 km/h).[3] On Bermuda, the storm severely damaged trees and telephone and telegraph wires,[14] while a ship sank along the coast.[2] Later on September 22, the cyclone turned northeastward and then eastward by September 25, remaining well offshore any other landmasses. Early the next day, the system weakened to a tropical storm, several hours before becoming extratropical about 560abbr=onNaNabbr=on west of Flores Island in the Azores.
Chenoweth began the storm slightly earlier, on September 15, and concluded that the cyclone became a hurricane late on September 16, but proposed few other changes.

With Mitchell noting in 1924 that this storm was first observed on September 29,[2] the official track begins about 500abbr=onNaNabbr=on northeast of the Leeward Islands. Moving northwestward for most of its duration, the storm strengthened into a hurricane on October 1 and a Category 2 hurricane on October 3. Early the next day, the cyclone passed about 45abbr=onNaNabbr=on southwest of Bermuda, which observed a barometric pressure of 981mbar. This formed the basis for the system's retroactive designation as a Category 2 hurricane with sustained winds of 100 mph (155 km/h).[3] On October 5, the storm curved northeastward and transitioned into an extratropical cyclone about 75round=5NaNround=5 southeast of the southern tip of Nova Scotia. The extratropical cyclone crossed Atlantic Canada and persisted until dissipating about halfway between Greenland and the British Isles on October 8.

A moderate tropical storm formed in the Caribbean south of Jamaica on October 4 and passed to the west of both Jamaica and the Cayman Islands. The cyclone then passed near or over Isla de la Juventud shortly before making landfall near Surgidero de Batabanó in present-day Mayabeque Province on October 6. Entering the Straits of Florida several hours later in a northeastward direction, the storm crossed the Florida Keys early the next day and made landfall near Cape Sable with winds of 50 mph (85 km/h). As the cyclone exited the east coast of Florida near Stuart late on October 7, Jupiter observed a barometric pressure of 1004mbar.[3] Late the next day, the storm transitioned into an extratropical cyclone about 175abbr=onNaNabbr=on southeast of Cape Lookout, North Carolina. The extratropical storm moved northeastward until dissipating about halfway between Bermuda and Nova Scotia on October 10.
The storm drove some vessels on the coast of Cuba ashore, and two people drowned in flooding on the island.[2] Climate researcher Michael Chenoweth proposed the removal of this storm from HURDAT, concluding that "bad data" led to its inclusion into the database and that the cyclone was actually part of the eighth storm.[15]

A tropical depression formed north of Honduras on October 7. Based on a ship recording a barometric pressure of 1004mbar late on that day, the system strengthened into a tropical storm early on October 8. The storm then made landfall in Cuba on the following day near Boca de Galafre, Pinar del Río Province. Slight further intensification likely occurred, with the cyclone peaking with winds of 50 mph (85 km/h) as it reached the southeastern Gulf of Mexico. However, the system became extratropical late on October 9 about 75round=5NaNround=5 southwest of Naples, Florida. The extratropical storm crossed Florida on October 10. Thereafter, the remnants moved slowly northeastward off the East Coast of the United States before accelerating over Atlantic Canada and dissipating offshore Labrador on October 16.

On October 12, a tropical storm was first observed just east of the Grenadines. Moving northwestward over the Caribbean, the cyclone struck Saint Croix and the main Virgin Islands on October 14. While passing north of Puerto Rico on the following day, the hurricane intensified into a hurricane, based on ships recording hurricane-force gales east-northeast of the Bahamas.[2] Moving generally northward, the storm passed just west of Bermuda on October 18. The island recorded a barometric pressure of 992mbar, which formed the basis of the hurricane's estimated maximum sustained wind speed of 85 mph (140 km/h).[3] Turning northeastward on October 19, the cyclone weakened to a tropical storm on the following day. Late on October 20, the storm made landfall on the south coast of Newfoundland and soon dissipated.

Although the Monthly Weather Review reported "an ill-defined cyclonic area" south of Cuba on November 3,[2] the official track for this storm instead begins about 40abbr=onNaNabbr=on east of San Salvador Island in the Bahamas, based on Mitchell's 1924 reanalysis and other available evidence.[2] Tracking generally northwestward, the cyclone likely peaked as a moderate tropical storm with winds of 60 mph (95 km/h), due to a lack of observations suggesting hurricane intensity.[2] After turning north-northeastward on November 6, the storm was last noted several hours later about 400abbr=onNaNabbr=on southeast of Cape Race, Newfoundland.
Chenoweth proposed four other storms not currently listed in HURDAT. The first such system formed over the Yucatán Channel on September 19. Moving generally northwestward and then northeastward over the Gulf of Mexico by September 21, the storm struck Louisiana and Mississippi. Several hours later, the cyclone dissipated over Choctaw County, Alabama. Chenoweth concluded that another tropical storm existed over the northwestern Caribbean by October 14. Tracking to the west, the cyclone made landfall in British Honduras (modern day Belize) two days later and crossed into Guatemala shortly before dissipating. Another unofficial storm formed over the southwestern Caribbean on October 23. The storm moved west-northwestward across far northeastern Nicaragua and northeastern Honduras before emerging into the Gulf of Honduras. Thereafter, the cyclone approached British Honduras but then turned northeastward near Glover's Reef. Chenoweth's study last notes the system approaching central Cuba on October 29. The final unofficial storm developed over the southwestern Caribbean on November 1. It moved west-northwestward and struck Nicaragua the next day, several hours before dissipating.[15]
