My informant, looking at the sky in the evening said, “Pink in the night, sailor’s delight. Pink in the morning, sailor’s warning.” At the time she said this the sky was pink. She finished, “It’s going to be a nice day tomorrow.” She heard this proverb from her father, who was in the navy. To her it means that the the weather will be nice the next day if the sky is red at night and if the sky is red in the morning the weather will be bad that day.

Annontation:

A phrase similar to this idea is in the bible in Mathew XVI: 2-3, Jesus says “When in evening, ye say, it will be fair weather: For the sky is red. And in the morning, it will be foul weather today; for the sky is red and lowering.”
