You’ve probably heard the old saying, “Red sky at night, sailor’s delight. Red sky in the morning, sailor’s warning,” but did you know it’s based on real weather wisdom backed by science?

The Weather Channel clarifies that the saying 'Red sky at night, sailor’s delight. Red sky in the morning, sailor’s warning' is rooted in scientific principles, not just folklore. Meteorologists explain that red skies are caused by high pressure trapping dust and particles in the atmosphere, which is often a sign of good weather.

In the mid-latitudes, where weather typically moves from west to east, a red sky at sunset indicates approaching high pressure and favorable conditions. Conversely, a red sky at sunrise suggests that good weather has passed and a low-pressure system, which may bring bad weather, could be on the way.

Truth behind “red sky at night, sailor’s delight”

Ever heard this one? Red sky at night, sailors delight. Red sky in the morning, sailors warning? Well, straight from a meteorologist's mouth, that's more than just weather lore. There's actually some science behind it. For starters, it's important to know that a dramatic red sky is often caused by high pressure trapping dust and other particles in the atmosphere. For the purposes of this discussion, high pressure equals good weather. Now, in the mid-latitudes where most of the U.S. lies, weather generally moves from the west to the east. So if you're seeing a red sky at sunset, which happens to the west, it means high pressure, aka good weather, is moving in. But if you see that red sky in the east at sunrise, it can mean that the good weather has already passed and a low-pressure system associated with bad weather may be next.
