Roosters are there yr round.
Feb can be tough as water clarity can effect fishing. No rain during that time of yr. Clear water makes for difficult fishing.
They can still be found and Adolpho and Cheva are very good at finding them.
You'll get into some large Jack's also.
I was down in July '12, we had days of 7+ roosters, caught on popper and live bait.
The large ones were caught on poppers.
Great to read, we're flying out of TJ and staying an extra day. Looking forward to the trip. Ed and I enjoy the inshore stuff and hopefully the conditions are right for a chance at a few roosterfish. If in I am hoping to pop the Saifish cherry!
