I just returned from a dive trip to St Helena island. It's in the South Atlantic, but you knew that.

It was awesome! Low-key island life, tons of fish, wrecks, lava topology and swim-throughs everywhere, whale sharks, mobulas, very fun. Water temp in the high 70's F, I wore a 5mm full wetsuit with a hood. Vis was "poor" due to recent storms, only 60-70 ft on most dives.
