Peak intensity	90 mph (150 km/h) (1-min)  970 mbar (hPa)

A hurricane was discovered located roughly halfway between Bermuda and Nova Scotia on September 9. The hurricane did not strengthen and began to gradually weaken as it moved to the south of Newfoundland. It weakened to a tropical storm and later became extratropical on September 11.[4]

Hurricane San Felipe of 1876

A hurricane first observed east of the Windward Islands on September 12 hit the islands that night. It strengthened to become a Category 3 hurricane, and hit between Yabucoa and Humacao, Puerto Rico, at that intensity on September 13. The storm made landfall in Puerto Rico and affected the island for over 10 hours with sustained winds of 100 mph. It then crossed over Hispaniola and Cuba before turning northward, avoiding Florida on the way. The weakened tropical storm headed towards the Carolinas, intensifying into a minimal hurricane before hitting near Wilmington, North Carolina, on September 17. The storm continued through the interior of the United States, dissipating on September 19 near Cape Cod.[4] In Puerto Rico, the lowest pressure was 29.20 inHg (989 mb) at San Juan and there were 19 deaths reported, but historians suspected the Spanish Government withheld the actual damage and death toll data for Puerto Rico.[5] At least two drownings occurred in Onslow County, North Carolina.[6] Flooding, damage to buildings, and uprooted trees were reported from Wilmington. A bridge across Market Street there was washed away.[7] In Puerto Rico the storm was remembered as the "San Felipe Hurricane" because it struck on September 13, the feast day of Saint Philip. Exactly 52 years later, Puerto Rico was struck by Hurricane San Felipe Segundo, a much more destructive and powerful cyclone.[5]

Tropical storm (SSHWS)
Duration	September 16 – September 18
Peak intensity	60 mph (95 km/h) (1-min)

The only tropical storm of the season was discovered on September 16 to the north-east of Antigua and Barbuda. It headed north, peaking at 60 mph (97 km/h) as it passed well to the east of Bermuda. It apparently dissipated on September 18.[4]

Category 2 hurricane (SSHWS)
Duration	September 29 – October 5
Peak intensity	105 mph (165 km/h) (1-min)

A tropical storm was first observed on September 28 just to the east of the Leeward Islands. It later strengthened into a hurricane as it passed near the Netherlands Antilles. It later peaked as a Category 2 hurricane before making landfall in Nicaragua. The storm reached the Pacific Ocean before it dissipated on October 5.[4] The cyclone severely damaged parts of Central America, inundating the Nicaraguan capital of Managua with floodwaters. People climbed rooftops to evade the floodwaters. On the east coast of the country, 300 homes were destroyed at Bluefields. The ship Costa Rica, in the eastern Pacific and bound for Acapulco on October 4, lost her hurricane-deck as well as the head of her main mast, main topmast, and gaff. She also lost one of her quarter boats and experienced a wind shift at 2030 UTC.[8]

Category 3 hurricane (SSHWS)
Duration	October 12 – October 23
Peak intensity	115 mph (185 km/h) (1-min)  958 mbar (hPa)

The Cuba-South Florida Hurricane of 1876

A tropical storm was discovered north of Panama on October 12. It moved very slowly and generally northward. It became a hurricane early on October 17 and passed just east of Grand Cayman, where significant effects were reported.[9] It attained a peak intensity of 115 mph (185 km/h) just before making landfall on Bejucal in western Cuba, where the barometer dropped as low as 28.32 inches of mercury (959 mb) on October 19.[10] The calm center of the storm passed over the capital Havana and then entered the Straits of Florida.[2] Just before 00 UTC on October 20, the eye of the cyclone struck Key West, Florida, which reported atmospheric pressure of 28.73 inHg (973 mb) and wind of 11 mph (18 km/h) veering to the southwest.[2] About six hours later, early on October 20, the eye made landfall on the Florida mainland near Chokoloskee with winds of 105 mph (169 km/h). Emerging into the Atlantic near Sebastian around 12 UTC, it produced a pressure of 28.82 inHg (976 mb) at Cape Canaveral.[2] The cyclone later passed north of Bermuda before dissipating on October 23. Bermuda recorded gale-force winds and a pressure of 29.30 inHg (992 mb).[4]

On Grand Cayman, where west winds occurred during the closest approach of the cyclone, severe damage and the destruction of 170 houses was reported.[11] In South Florida, the hurricane produced tides of 8 feet (2.4 m) to 10 ft (3.0 m) on Biscayne Bay, but local ships rode out the storm in a natural anchorage called Hurricane Harbor, on the west side of Key Biscayne.[12] The bark Three Sisters was wrecked on Virginia Key, her cargo of lumber being salvaged by local residents.[12] The storm flooded the islands on Biscayne Bay and destroyed many structures.[13] On the Lake Worth Lagoon, the cyclone snapped or blew down large mastic and banyan trees, each more than 3 ft (0.9 m) in diameter and believed to have been hundreds of years old. All vegetation was stripped of foliage and branches were downed, while settlers' furniture was blown away. After the storm, the Atlantic Ocean appeared yellowish-brown due to silt, and numerous fish and sea mammals, including porpoises, were found beached.[14] The settlement that later became Palm Beach was destroyed.[15] Two decades later in 1896, the storm was still noted by settlers as among the worst ever in South Florida.[13] In passing over Eau Gallie near Melbourne, the calm eye lasted about four hours between 0830–1230 UTC.[16]
