Accumulated Cyclone Energy (ACE) Rating
|ACE (104 kt2) – Storm: Source|
ACE is the result of a storm's winds multiplied by how long it lasted for, so storms or subtropical storms (Originally not included up until 2012) that at lasted a long time , as well as particularly strong hurricanes , have higher ACE totals. Tropical Depressions are not included in season total.
This is a table of the storms and their effects in the 2026 South Atlantic cyclone season. This table includes the storm's names, duration, peak intensity, Areas affected (bold indicates made landfall in that region at least once), damages, and death totals. Deaths in parentheses are additional and indirect (an example of an indirect death would be a traffic accident), but are still storm-related. Damage and deaths include totals while the storm was extratropical, a wave or a low. All of the damage figures are in 2014 USD (the listed damage figure is in millions).
