It is basically a true statement and it has pretty much proven, Westerly and Southern winds produce the best fishing results most of the time, but there is more to it than wind direction… It has more to do with high and low pressure systems. Salmon don’t know or care which direction the wind is coming from, but they do care about water temperature, currents, and food, which winds play a large role. Sometimes good, sometimes bad. The first thing any wind will do is stir the baitfish and create upwelling. In most cases off WCVI and south VI that would be, baitfish are pushed farther offshore unless you are in an inlet. In my case in Puget Sound, I just move from one side of the sound to the other. Goes back to find the bait – find the fish. With an easterly wind on WCVI, the baitfish will tend to scatter more resulting in the scattering of the salmon making it difficult to find them, but you still can. If you have, constant winds from any direction over two or three days it will push the bait and salmon to the windy side.
Pay more attention to the atmospheric changes. A period of unstable weather and/or big barometric shift puts the fish into a more negative mood than stable weather periods and watch for a the period prior to a drastic change as that can be some really good salmon fishing. In addition, remember a constant east wind will push the warm surface water offshore, and pull the coldwater to shore causing coldwater upwelling. Watch the water temperature, if you find that upwelling you will normally find the fish, as salmon prefer water roughly around 50 degrees these cold water currents will produce some good fishing regardless of wind direction. If you are close to shore on WCVI and fishing an easterly wind in 65-70 degree water (which I have seen)... good luck, and hope there are a lot of fish passing!
Low pressure creates "counter clockwise" winds
High pressure creates "clockwise" winds
Just my 2 cents!
