A South Atlantic tropical cyclone is a rare cyclone that occurs in the south half of the Atlantic Ocean. These are rare due to high wind shear and lack of space for the cyclones to form. If there was to be a 'Hurricane Season' or 'Cyclone Season' it would last from November to April, with March being its peak. These cyclones would be given identifiers SL, for example INVEST 90SL or Tropical Depression 1-SL.
