Surely you’ve hear the old saying “Red sky at night, sailor’s delight. Red sky in morning, sailor’s warning”. But is this adage actually true? Let’s see what the ‘experts’ say. Let’s look at the first part
-Red sky at night, sailors delight. When we can see a red sky at night, this means that the setting sun is sending its light through a large concentration of dust particles. What this usually indicates is that high pressure and stable air are coming in from the west. Basically good weather will follow.
But what about “Red sky in morning, sailor’s warning”. A red sunrise can mean that a high pressure system (meaning good weather) has already passed, thus indicating that a storm system (low pressure) may be moving to the east. A morning sky that is a deep, fiery red can indicate that there is high water content in the atmosphere. So, rain could be on its way.
Of course this isn’t 100% accurate, but it seems to be a pretty good indication and besides, it’s kind of fun to believe.
