Getting married on the first few days of the full moon is a good omen.
One Saturday change in the Moon is enough, as it is always followed by a severe storm.
Seeing a new moon through closed windows is unlucky.
If on her cheeks you see the maiden's blush, The ruddy moon foreshows that winds will rush.-Virgil, Roman poet (70–19 B.C.)

When the moon runs high, expect cool or cold weather.
A pale full Moon indicates rain, while a red one brings wind.
