Origin of the Phrase Under the Weather - Nautical maritime history

Have you ever wondered about the origin of the phrase under the weather? When we feel unwell today, we often use this gentle expression. The truth behind the saying belongs to maritime history on nineteenth-century sailing ships.

Quick Answer: Origin of the Phrase Under the Weather

The phrase “under the weather” originated in nineteenth-century maritime sailing ships. When passengers or sailors became seasick during storms, captains sent them below deck to the leeward side beneath the windward “weather rail.” Being below the weather rail sheltered sick travelers from wind and crashing waves. Over time, the phrase expanded from literal seasickness to any mild illness.

The Nautical Anatomy of Sailing Vessels

Life aboard a nineteenth-century sailing ship was physically demanding. Ocean swells constantly rocked wooden vessels during transatlantic voyages. Passengers and novice crew members frequently suffered severe motion sickness.

Sailors used specific terminology for ship sides. The windward side facing the wind was the weather side. Its protective barrier was called the weather rail.

Crashing waves and freezing spray battered the weather rail constantly. Standing on the weather deck during storms worsened nausea quickly. Officers ordered sick travelers below deck for safety.
