dead calm
Zero wind whatsoever
Dead calm describes a complete absence of wind or movement, especially at sea.
The phrase emphasizes total stillness—not merely calm, but utterly motionless: The sails hung limp in the dead calm.
It extends to any situation of profound quiet or inactivity: The office fell into a dead calm after the announcement.
