True.  Good things with Hawaii compared to places like in South East Asia is that Hawaii is surround by really deep ocean water that tends to be cooler than the shallower water such as the seas surrounding places like Japan or Philippines,   Also massive mountains Mauna Kea & Loa on the big Island act like giant wind breaks since most hurricanes that hit Hawaii generally travel East to West hit the Big Island first since  they generally follow the West to East rotation of the earth.  The exceptions are Hurricane Iniki which traveled South of the Hawaiian islands but took an an unexpected north route up to Kauai. Of course as more heat is trapped in earth's atmosphere, the ocean temperatures, even around deep waters surrounding Hawaii will get warmer & warmer.  Just takes a degree or two to really keep Hurricanes at full strength that start off around Mexico and make their way to Hawaii.
