The residents of Catfish Row are all gathered in Serena's room for shelter from the hurricane. They drown out the sound of the storm with prayers and hymns ("Oh, Doctor Jesus") while Sportin' Life mocks their assumption that the storm is a signal of Judgment Day. Clara desperately sings her lullaby ("Summertime" ). A knock is heard at the door, and the chorus believes it to be Death ("Oh there's somebody knocking at the door"). Crown enters dramatically, having swum from Kittiwah Island, seeking Bess. He shows no fear of God, claiming that after the long struggle from Kittiwah, God and he are friends. The chorus tries to drown out his blaspheming with more prayer, and he taunts them by singing a vulgar song. ("A red-headed woman"). Suddenly, Clara sees Jake's boat float past the window, upside-down, and she runs out to try to save him, handing her baby to Bess. Bess asks that one of the men go out with her, and Crown taunts Porgy, who cannot go. Crown goes himself, yelling out as he leaves "Alright, Big Friend! We're on for another Bout!" The chorus continue to pray as the storm rises.
