Yeah, calling the direction of sunrise "east" isn't very accurate, either, but it's still better than the arc of the shadow. If you're not near the poles (and you're not; this island is comfortable in bare feet even while your hometown is snowy) it's probably good enough for a rough description of the shape of the island, but for any navigation-related purposes, you'll want to do better.

I have to wonder if we can get anything useful from the extent of the tides, but for a nearly-flat sand island out of sight of any other land, it's probably redundant with the other information we have.
