Wives Tales-Red Sky at Night, Sailor’s Delight. Red Sky in Morning, Sailor’s Warning

When we see a red sky at night, it means that the setting sun is sending its light through a high concentration of dust particles, which usually indicates high pressure and stable air coming in from the west, usually followed by good weather. A red sunrise can mean that a high pressure system (good weather) has already passed, thus indicating that a storm system (low pressure) may be coming.
