First Step in Weather Casting: Step outside and look at the sky!
Red sky at night, sailor's delight; Red sky in the morning, sailors take warning.

The evening red and morning gray are sure signs of a fine day, But the evening gray and the morning red, makes the sailor shake his head.
These expressions have some basis in meteorological fact. In the mid latitudes of the Northern Hemisphere, storms generally travel with the jetstream from west to east. A red sky in the morning may indicate that is rising in clear eastern skies and casting its rays on storm clouds approaching from the west. A red sky at sunset indicates clouds to the east, with clear skies moving in from the west, allowing the sunset to be seen.
A ring around the sun or moon, means rain or snow coming soon.
If a circle forms around the moon, Twill rain soon.
The circle that forms around the sun or moon is called a halo. Halos are formed by the light from the sun or moon refracting (bending) as they pass through the ice crystals that form high-level cirrus and cirrostratus clouds. These clouds do not produce rain or snow, but they often precede an advancing low pressure system which may bring bad weather. This form of weather prediction is accurate about 65% of the time.

Rainbow to windward, foul fall the day rainbow to leeward, rain runs away.
A windward rainbow indicates rain upwind, so it may begin raining soon. A rainbow behind the wind or to leeward implies the rain has probably past.

Sun sets Friday clear as bell, rain on Monday sure as hell.
Cold is the night When the stars shine bright.
The more moisture there is in the sky, the more the light from the sun, moon, and stars is dimmed or reddened. A very clear sky permits more starlight to penetrate, thus the stars appear brighter. Moisture tends to hold in the day's heat, like a blanket. The less moisture there is in the air at night, the more the temperature tends to fall. The brighter the stars appear, the cooler is the

If clouds are gathering thick and fast, Keep sharp look out for sail and mast, But if they slowly onward crawl, shoot your lines, nets and trawl.
In the morning mountains. In the evening fountains.
The mountains refer to high, billowing cumulus clouds, indicative of instability and possible development of cumulonimbus clouds and a late afternoon or evening thunderstorm.

Step Two for the Weather Man: Check to see from which quarter the wind blows!
"A wind in the south has rain in her mouth."
A southerly wind usually carries moisture from the Gulf of Mexico. It causes the air to become more humid, and, more likely to form rain clouds.
When the wind is blowing in the North, no fisherman should set forth, When the wind is blowing in the East, 'Tis not fit for man nor beast, When the wind is blowing in the South it brings the food over the fish's mouth, When the wind is blowing in the West, That is when the fishing's best!

When rain comes before the wind, halyards, sheets and braces mind, but when wind comes before rain, soon you may make sail again.
No weather's ill if the wind be still.

Weather Casting Rule Number Three: If you don't trust your own judgement, check with the local wildlife!
Sea gull, sea gull, sit on the sand, It's never good weather while you're on the land. or when sea-gulls fly to land, a storm is at hand.

Sharks go out to sea at the approach of a wave of cold weather.
When porpoises sport and play, there will be a storm.
When parrots whistle, expect rain.
Failing All That, Choose Step Number Four: The most important weather rule of all for sailors!
Whether the weather be fine Or whether the weather be not Whether the weather be cold Or whether the weather be hot We'll weather the weather Whatever the weather Whether we like it or not.
