10 Weather Omens That Once Signaled Doom or Change

Throughout history, unusual weather events were often seen as omens of doom or major change. Lacking scientific explanations, people turned to folklore to interpret the skies.

Phenomena like eclipses, red skies, and strange animal behavior were believed to warn of war, death, or disaster signs from nature or the divine.

In many cultures, a red sun or sky was seen as a warning of war or disaster. The saying “Red sky at morning, sailors take warning” captures this idea, suggesting that a crimson sunrise may signal an approaching storm or trouble ahead.

2. Solar and Lunar Eclipses

Eclipses were historically seen as ominous signs. In ancient Mesopotamia, lunar eclipses were carefully recorded and interpreted as warnings of impending disasters, such as war or the death of a king. These celestial events were believed to reveal the fate of rulers and empires.

On May 19, 1780, daytime turned unusually dark across New England and parts of Canada, sparking panic and fears of the apocalypse. Though scientists later traced the event to forest fire smoke, fog, and cloud cover, many at the time believed it was a supernatural or divine warning.
