The 1929 Atlantic hurricane season ran through the summer and the first half of fall in 1929. It was a mostly quiet season in the Atlantic as only five tropical cyclones formed during the season, with the distance between the first and second storms being nearly three months. Of the five storms that formed, three reached hurricane strength, and one became a major hurricane.

Most of the season's damage and fatalities was caused by the second hurricane of the season. It formed north-east of the Caribbean, and hit the Bahamas as a Category 4. It killed 50 people in the Bahamas and caused damage in the Florida Keyes. Another storm hit central Texas as a Category 1, causing light damage. The other one stayed out to sea.

Storms

Hurricane One

Category 1 hurricane (SSHS)
Duration June 27 – June 30
Intensity 90 mph (150 km/h) (1-min),  982 mbar (hPa)

After barometric pressures in the western Gulf of Mexico had been low for several days, the steamship Chester O. Swain encountered a disturbance of "probably moderate intensity" offshore of Texas on June 28.[1] However, in post-analysis, a tropical storm had actually developed in the southwestern Gulf of Mexico developed on the previous day.[2] The storm was abnormally small, having a diameter of only about 20 miles (32 km).[1] It moderately intensified and by early on June 28, the storm became a hurricane. While just offshore of Texas, the hurricane reached peak winds of 90 mph (150 km/h).[2]

Shortly after making landfall near Matagorda Bay at the same intensity, a minimum barometric pressure of 982 mbar (29.0 inHg) was reported. The storm then accelerated westward across the Southwestern United States and dissipated by June 30.[2] Due to the small nature of the storm, squalls associated with this system effected most areas for less than four hours. A combination of storm surge, strong winds, and heavy rainfall, the storm damaged fishing vessels, uprooted trees, smashed windows and also downed telephone and telegraph lines.[3] Otherwise, damage was from this storm was minimal.[1]

Hurricane Two

Category 4 hurricane (SSHS)
Duration September 22 – October 4
Intensity 155 mph (250 km/h) (1-min),  924 mbar (hPa)

Of this season's 5 storms, the 1929 Florida Hurricane (or the Great Andros Island hurricane) was the most notable. In the Keys, roofs were torn off houses, debris was thrown through the air, and small craft were sunk in the harbors. It grazed the southwest coast and struck again at the Big Bend area as a strong tropical storm. The storm dissipated inland. It killed nearly 50 people in the Bahamas and caused catastrophic damage on Andros Island where it hit as a strong Category 4 hurricane.

Tropical Storm Three

Tropical storm (SSHS)
Counterclockwise vortex
Duration September 25 – September 27
Intensity 60 mph (95 km/h) (1-min),  997 mbar (hPa)

Historical weather maps indicate that a low pressure area was embedded within a west to east oriented stationary front on September 24. It quickly detached from the stationary front and acquired a closed circulation while tracking across sea surface temperatures of 80F °C (Template:Convert/°F/80F °C). Early on the following day, a tropical depression formed just west of Bermuda. Later on September 26, the depression strengthened into a tropical storm.

Tropical Storm Four

Tropical storm (SSHS)
Counterclockwise vortex
Duration October 15 – October 19
Intensity 60 mph (95 km/h) (1-min),  ≤999 mbar (hPa)

A tropical storm formed on October 15 in the eastern North Atlantic south-southwest of the Azores. It moved west-southwestward before turning to the northwest, becoming extratropical on October 19.

Hurricane Five

Category 1 hurricane (SSHS)
Counterclockwise vortex
Duration October 19 – October 22
Intensity 80 mph (130 km/h) (1-min),  ≤997 mbar (hPa)

Originally considered a continuation of the previous storm, the final storm of the season formed on October 19. It moved northeastward, becoming a hurricane and reaching peak winds of 80 mph (130 km/h). The hurricane turned to the northwest, becoming extratropical on October 22 and dissipating the next day.
