It was originally related to how fast the sea can change depending on the weather. It is first mentioned in Shakespeare’s The Tempest in 1611.
Full fathom five thy father lies,
Of his bones are coral made,
Those are pearls that were his eyes,
Nothing of him that doth fade,
But doth suffer a sea-change,
into something rich and strange,
Sea-nymphs hourly ring his knell,
Hark! now I hear them, ding-dong, bell.
It is now used to denote a more figurative change. The archaic meaning relates to a literal change. Charles Dickens, Henry David Thoreau, and P.G. Wodehouse all used it in their literature to allude to the suffering of a character. In the Tempest Shakespeare seamlessly interweaves the literal and the figurative.
