As the wind related proverb says “When the wind is east the fish bite the least, when the wind is west the fish bite the best.” Wind is an influential factor in fishing behavior as it stirs the food chain, provides oxygen and cover from the sun with wave action. Constant wind blowing from the same direction over days will migrate game fish on the windy shoreline to feed on baitfish. Water temperatures will increase also as the surface water is pushed by the wind. This is especially helpful in Spring and Fall seasons as the angler seeks the warmest water. Westerly and Southern winds are proven to produce the best fishing results as the proverb states. Clouds and cloudy conditions have similar effects as wind by reducing sunlight on and near the surface. Light sensitive fish will become more active, a combination of light wind (chop) and cloud cover condition is excellent for surface lures.
Here is another rhyme, adding North wind to the times not to go fishing
When the wind is in the east,
'Tis neither good for man nor beast;
When the wind is in the north,
The skilful Asher goes not forth;
When the wind is in the south,
It blows the bait in the fishes' mouth;
When the wind is in the west,
Then 'tis at the very best.
Easterly winds tend to be produced by low pressure, which, apparently fish dont like, westerly winds tend to be produced by high pressure which, apparently the fish prefer, so its all down to atmospheric pressure.
