As I made the list, with the help of others, I began to wonder myself what it meant about noir. The most obvious thing that occurred to me was that it doesn't fit the characterization of noir as involving a cityscape and all its associated structures. In that divergence, it's like desert noirs. It's evidence that noir is not tied to a locale, not that we need more such evidence, but it's doubtful that this aspect of it has been compiled or duly noted before.
The number of these surprised me.
The role of water and/or beach in these films might be a possible avenue of exploration. I'm not a film critic or analyst or sociologist in any way, shape or form. This kind of thing is the province of others like you who are able to and take the time to develop the hypothesis and debunk those prevalent theories that do not fit the facts. Clearly, movies like "House by the River" and "The Reckless Moment" make the water an integral part of the story. So do some others. Others make use of the harbor setting, and that brings to mind the Belgian "Seagulls die in the harbor" (Meeuven sterven in de haven) (1955). It uses the harbor quite a lot, but also a grassy field. I'm adding that to the list too.
Rio does not make the list. It has no physical or metaphorical presence of the beach at Rio. It's mainly into nightclub, prison and financial scenes.
On the other hand, for some reason, this discussion has made me think of another one that we forgot and that's "A Place in the Sun", where the water is absolutely critical and pervasive.
I think what's important is how the harbor or beach or river or ocean or cliffs or beach houses are incorporated into the story and contribute to its meanings.
If we start to add neo-noirs and post-1960 noirs to the list, it will lengthen quite a lot, I suspect. Dark Harbor (1998) and Qui? (1970) are two I've seen recently. Against All Odds (1984) is another that uses the beach.
