red sky at night

The phrase "red sky at night" is part of a common weather adage that states "Red sky at night, shepherd's delight; red sky in the morning, shepherd's warning." This phrase suggests that if the sky appears red during evening hours, it foretells fair weather the next day, bringing joy to shepherds. It is contrary to the belief that a red sky in the morning implies stormy weather later in the day. However, this adage may not hold true in all geographical locations or weather conditions.
