Old Saying???? - True or False

[Dmarina]

The old saying: "RED SKY AT NIGHT, SAILORS DELIGHT - RED SKY IN MORN, SAILOR BE WARNED" - Theoretically, is there any proof of this? We have often wondered. We use it all the time, but don't know if it is TRUE OR FALSE. Thanks for any answer.

the part of red sky in the evening is true; books about meteorology state it also; the weather/ front is moving from west to east => no clouds in the evening make red sky and therefore means there's nothing coming
but red sky in the morning i think it's not so true

another old forecasting/ believe is to check the moon at night; if the moon doesn't have a gray ring around it, there's no clouds therefore no strange weather; of course this kid of predictions are durable for cca 12 hours max

i investigated these old techniques and thay matched with satellite forecasting a lot

in our town we have a big mountain in sight; the mountain is kind of a barrier from bad weather -> another old forecasting is that when it has a small hat of clouds on its top it will be good weather
and it matches with technology forecasting too

Most of the old sayings are based in truth to some degree, or they wouldn't have lasted as long as they have.

The red sky at night usually means that the air to the west is very dry and there is a fair amount of airborne dust, causing the red color to the sunset. That generally presages good weather, since weather systems tend to move west to east.

My understanding, and I could be wrong, SD has it half right.

What I was told is that the southern trade down the eastern atlantic would look for signs of Siroccos off Africa, if in the morning, the sky was red (in the east of course), that would mean the winds are kicking up dust storms, that was the warning to reef down.

If on the other hand the sky was red at night, the assumption was that the wind storm had passed and moved out to sea.

I'm not too sure how this would work for the eastern seaboard of the US, but it does have some validity on the west coast where Santanas, Chubascos, coromuels, and maybe an elefante or two are generated over land and do change the color of the sky to the east.

It is basically true as explained here:
Is “Red sky at night, sailor’s delight,Red sky in morning, sailor’s warning” true? Everyday Mysteries
