Red sky in morning, Sailors take warning.
Red sky at night, Sailors' delight.
Evening red and morning gray, help the traveler on his way.
Evening gray and morning red bring down a rain upon his head.
Rainbow in the morning
gives you fair warning
Beware the bolts from north or west;
In south or east the bolts be best.
Mackerel skies and mares' tails
Make tall ships take in their sails.
