Wind in East

For those who have never heard it, or dont know the full rhyme (?)...

An East wind is seen as unfavourable for fishing.
"wind in east" is a little ditty that you sometimes hear.
Any truth in it? Well, Ive often had very bad days sport in East winds....
But then Ive had bad days sport in ANY wind direction....

When the wind is in the East, the fish bite least.
When the wind is in the North the fisherman does not go forth.
When the wind is in the South it blows the bait into the fishes mouth.
When the wind is in the west the fishes doth bite best.

I guess its South-Westerlies then ! :-)
