Tropical cyclones develop with surface waters of some 80F or so, but as they form and move along, they cause mixing near the surface so the part of the sea surface that the front part of the storm is over has been churned up and is now likely lower than that threshold, or at least, cooler. With some recent storms, water was over 80F at depth of 100 or even 200 meters. This means that the cooling caused by churning essentially doesn’t happen and the hurricane can grow much stronger.
