Generally its pretty late in the year to be catching Kings or Cobia. But fish the conditions. Water temp will depend on wind direction. If the wind is NE or E and the water is warm and clear, try for a King. On September 19th last year I hung two Kings from a pier and saw a Cobia mouth a bait. We had a light NE wind and warm clear water. The next day the NE popped up to 30mph and the water got rough and muddy. That was the end of King/Cobia for the year, but several big Drum were caught. I remember meeting Drumdum for the first time one of those nights.
Anyway, chances are, you're gonna want to be Drum fishing.
