Saltwater Fish Temperature Preferences

Temperature preferences are only a rough guide, and Farhenheit at that. But they will let you avoid areas where fish are most unlikely to be found. Expect a variation a few degrees one way or the other. On windy days, for example, oxygenated surface areas may attract species to areas above their optimum. Such is also the case when baitfish are in warmer water.
