If the moon is seen between the scud and broken clouds during a gale, it is expected to cuff away the bad weather.
It is unlucky to sleep in the moonlight, or worse, be born in the moonlight.
If on her cheeks you see the maiden's blush,
The ruddy moon foreshows that winds will rush.-Virgil, Roman poet (70 B.C.-19 B.C.)
Seeing a new moon through closed windows is unlucky.
When the moon is visible in the daytime, the days are relatively cool.
Plant the bean when the Moon is light;
Plant potatoes when the Moon is dark.
If one gets ill on the eighth day of a new moon they will die.
Moonlight nights have the hardest frosts.
