Looking for weird fiction set by the coast, beach, or just somewhere tropical.

I love weird, unsettling fiction, and am going on vacation to the coast in a few weeks. It's fun to try to match my reads with my surroundings at times, and since this is the perfect opportunity to do that, I figured I'd ask around! Any suggestions would be super appreciated. Annihilation and the rest of the Southern Reach trilogy are some books I've read and enjoyed that more or less fit this criteria.

That said, I’m also open to anything! It doesn’t have to be weird fiction. If it’s a great beach read, I’m all ears.
