A South Atlantic tropical cyclone is an unusual weather event which occurs in the southern Atlantic Ocean, south of the equator. Strong wind shear (which disrupts cyclone formation) and a lack of weather disturbances favorable for cyclone development make any hurricane-strength cyclones extremely rare.

If a "hurricane season" were to be demarcated in the South Atlantic, it would most likely be the opposite of the North Atlantic season, from December to May with mid-March being the peak when the oceans are warmest in the Southern Hemisphere.
Below is a list of known South Atlantic tropical cyclones.
Cyclone Catarina - Main article: Cyclone Catarina
Cyclone (or Hurricane) Catarina was an extraordinarily rare tropical cyclone, forming in the southern Atlantic Ocean in March 2004. Just after becoming a hurricane, it hit the southern coast of Brazil on the evening of March 28, with winds estimated near 135 km/h (85 mph), making it a Category 1 storm on the Saffir-Simpson Hurricane Scale.

Angola Tropical Cyclone of 1991 On April 10, 1991, what may have been a tropical depression or tropical storm formed in the eastern South Atlantic, recorded by weather satellites off the coast of Angola. It reached a peak on the 13th, and dissipated 2 days later, drifting west-southwestward from its beginning. Of the few South Atlantic tropical cyclones that existed, this was the only one in the eastern Atlantic. This was also the first South Atlantic tropical cyclone ever observed. April 10 is the 100th day of the year in the Gregorian calendar (101st in leap years). ...

Tropical Cyclone of January 2004 A small area of convection developed on a trough of low pressure in mid January off Brazil. It organized and appeared to become a tropical depression on January 18th. The next morning, it had a small CDO and well-defined bands, and the system, either a weak tropical storm or a strong tropical depression, likely reached its peak. Located 150 nm southeast of Salvador, Brazil, it weakened as upper level shear, typical for the basin, prevailed. The depression moved inland on the 20th as a circulation devoid of convection, and dissipated the next day over Brazil, where it caused heavy rains and flooding. This would mark the first time in recorded history that two tropical cyclones (Catarina and the January storm) have been seen during the same year in the South Atlantic, and may be considered to make up the 2003-04 South Atlantic hurricane season. January 18 is the 18th day of the year in the Gregorian calendar. ...

2004-2005 Tropical Cyclone Season
Tropical Depression of December 2004 On December 31, 2004, a weak tropical depression formed near S30.2 W47.5. QuikSCAT scatterometer data clearly showed a well-developed cyclone which had formed from a frontal low. The system later fell victim to high-level wind shear, as is common in the South Atlantic.

Subtropical Storm of January 2005 A low-pressure system in the open South Atlantic Ocean developed convection and some circulation on January 30th. It appeared to have some Subtropical characteristics, but unlike Catarina 10 months earlier, it dissipated from strong upper level shear. January 30 is the 30th day of the year in the Gregorian calendar. ...
