My hypothesis is that the colder water from out beyond the no wake marker is inverting with the warmer water in the shallower area. If you look at the 3 month graph, you can see the last warm up in March really heated up the water to 40 degrees, but then it quickly went back down.

There is also a little bit of a "current" for lack of better description that is moving water through that area and under the LI bridge so that water isn't exactly stagnant.

Also it remains relatively shallow quite a distance out from the NWZ marker for at least another 300 yards it's still only 15 to 20 feet deep towards 5 mile IS and the entrance to Braun Bay. Even then it drops off pretty slow. The same is true on the opposite side of the LI Bridge, got to get beyond the little island and first black marker before the bottom starts to show any depth beyond 15 feet.
