More anecdotal stuff along the same lines:

One of the people running the MV _Moonlighting_ liveaboard dive boat in
the Madang area of Papua New Guinea recently told me that the extensive
bleaching that's lately been affecting Madang Lagoon isn't anywhere near
as apparent around the islands further offshore.  Current velocities in
the passes and along the Madang barrier reef can be very high, but the
more distant islands are known for having quite extreme currents.

I don't know how different the water temperatures are at these sites, but
I'd guess that those in the Lagoon are higher and water exchange would
certainly be lower.  Of course, then there are all of the other potential
