To me the water color is as important if not more important than the temp for the offshore fish. On Temp Break there is a bar graph to the left side that gives a number to the colors.

Tuna like the clean stuff from .1 on up to .25, yellowtail aren't to picky but it's rare to find them in the green stuff offshore. Marlin and dorado will expand the zone a bit and push into the clean green water if the bait is plentiful. On the chart that's where the darker blue is fading into the light blue.

This time of year the temp is good enough everywhere to hold fish, The reason we find them in one place and not the other is water clarity and bait.

That's how I see it for what it's worth.
