‘Red sky in morning, sailors take warning; red sky at night, sailors’ delight’We hear it all the time, but have you ever questioned this chunk of weather wisdom’s origin? In Matthew XVI: 2-3, Jesus Christ is quoted as saying, “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.”ADThis one has some truth to it. In the mid-latitudes where most marine commerce takes place, weather systems propagate from west to east. Much as with the red sky mantra, a blanket of high cirrus clouds in the wintertime often heralds foul weather.
