I would think that coconuts would do well there.
I am familiar with coco groves that start within a few feet of the high tide line.
During hurricanes/tsunamis, these groves are under water (in sandy soils), plus the rest of the year, they are subjected to salt spray.
Besides food and income, they are a plentiful source of water. I know several villages where potable water is in short supply. The residents drink coco milk with every meal. The fronds are also a good supply of renewable building supplies.
