Is red sky in the morning sailors take warning red sky at night sailors delight is based on a myth or a fact?

Both, but more on fact. Since the sun comes up in the east, a red sky in the morning often means there is adverse weather developing, whereas if there's red sky at dusk, then the inclement weather has passed and there will be a nice day the following day.
It's a simplification based on the fact that most weather systems move from west to east. It's not a "fact", but it is based on probable events in the next 12 to 24 hours.
