Just a quick question for any of you willing to contribute. I hear a lot about looking for "temperature breaks", rips, upwellings, etc. while offshore. How much of a temperature break are we talking typically, and do a lot of you specifically look for this in addition to the other signs (birds, debris, etc.)? I made it a point to look the other day while I was out and never saw more than maybe a degree or so of shift in temps. Most of the time it was low 77's to upper 77's, near 78. I know inshore, a degree or so can really make a difference to where fish will hold, especially during the extreme temperature cycles, but how much of a temperature change can be seen in one of these upwellings?
