|“||Your destiny grows clearer, Jason Grace. When the choice come again-storm or fire-remember me. And do not despair.||”|
Notus the son of Eos and Astraeus. He is the South Wind, one of the four Anemoi. As his brother, Boreas the North Wind resides in Quebec (the oldest Northern American settlement), Notus may reside in one of the older South American settlements. His palace is located on the coast of northern Africa. His Roman counterpart is Auster.
Notus' winds are heavy and filled with moisture, creating fog and mists. He was associated with the desiccating hot wind of the rise of Sirius after midsummer, was thought to bring the storms of late summer and autumn, he was also feared as a destroyer of crops.
Notus is mentioned by an angry Boreas since Notus supposedly gets to spend the spring break in Cancún. Also, Chiron mentions that Notus is the most gentle of the winds and that the heroes of the Prophecy of Seven should use his winds to sail to Greece.
Notus is mostly seen in his Roman aspect, Auster, during his final meeting with Jason Grace. At the end of the meeting, he retakes his old Greek form to signify Jason's decision to remain at Camp Half-Blood, rather than the more traditional Camp Jupiter.
Notus is described as a bronze-skinned old man in a fiery Greek chiton and a wreath of shaggy, withered, smoking barley on his head.
Auster, Notus's Roman aspect, is more warlike and militaristic than his Greek counterpart. He is also known to represent southern storms, unlike the fiery Notus. However, he seems to be less quick to anger when compared with Notus.
In The House of Hades, Jason Grace met with the South Wind on several occasions- sometimes as the fiery Notus and sometimes as the stormy Auster. As Auster, the South Wind helps Jason decide where he truly belongs. Once Jason chooses Camp Half-Blood, Auster changes back into Notus.
- Aerokinesis: As the God of the South Wind, Notus has divine authority and absolute control over the air, though not as much as Zeus and Aeolus.
- Pyrokinesis: As the God of Summer, Notus has control over fire and heat. Zethes thinks that Leo is one of his demigods because "he smells like fire".
- Seasons Alteration (limited to Summer): As the God of Summer, Notus has power over this season and things associated with it.
- It is possible that Notus has demigod children since when the Boreads were confronting Leo about the fire they could smell, Zethes thought he was a 'child of the South Wind' sent to spy on them. This also hints that Notus likely has some connection to and/or power over heat and fire, much like Boreas with his cold and ice/snow powers.
- His Norse equivalent is Frey.
