North to south

I have always wondered about this and am hoping some of you might be able to help educate me.



Assuming Galveston bay, when's small northern hits like this and blows north for two days then switches to south west, what does that do to the fish? Do they tend to be more aggressive or less aggressive? Is the water churned up and off color? Is there a rule of thumb as to how long you wanna sit after a front, before you fish?



I remember hearing as a kid that it's best to wait 3-4 days after a front but is that true?



Thanks in advance gang.
