..like mentioned above, a southernly wind will push the
top water column north, including anything in it..ie:baitfish/sea-weed/etc..While the baitfish circle for safety, they have no choice but to follow the easiest path, sometimes swimming along the weeds. Fighting the water would make them an easier target for their predators. Picture a school of baitfish circling for safety...yet traveling east @1mph, now add 20mph winds from the southwest...which direction are they traveling now? If the wind is traveling @20mph...it could possibly make the top water column travel @3mph, therefore decreasing their progress by 2mph...I haven't done the math, but this is how I've seen things happen. Of course the tide is a very strong factor also with the exchange of water..
In the picture below, Ex. <A>..these baitfish are heading east while the wind is blowing from the southwest...as the top water column gets pushed, so do they...they could go deeper to escape being forced, but we all know whats waiting in the depths

..so they stay up top. They will still try to follow the safest path. In the picture below.. they headed right towards the bowl, Ex. <B>...but eventually, when provoked, they will end up on your feet. Imagine what a couple of days with southwest winds could do. Most do better the days following the start of the winds, and also, most Rhode Island fishing locations face South. I'd imagine that
saying originated in R.I....
Its just as easy to apply this formula to water temps...I just think it's a more gradual change. With the warmer water being south of us...and most fish migrating back from the south

...I'm sure you can do the math.
...I'm far from a marine biologist or meteorologist or even a gynecologist, this is just my $.02...this is how I've seen things go down in my experiences..
Happy Fishing
