Yep. Warm water is inside. This will change with winds/currents etc but will give you an idea of what’s going on.
Without a fish hawk/sub troll you will have to look for bait and marks and fish them. I will say that we have taken several decent fish this year way out of temp. In the warm water above the cold water. Keep in mind that as we progress through August and into September, temp will become less important for the staging kings. Structure often times becomes more important for these staging fish.
