"Beach noir" is a great little sub-category, and I think back in the day (probably when Marie used to post here) we had a pretty good list of what these films were. Obviously FEMALE ON THE BEACH is a charter member! Maybe it would be a good thing if we re-compiled a list of them now--wondering if you've already done so, Mike.
And the good news for SF folks is that this film will be screened at the Castro on Wednesday, August 24 (in tandem with WICKED WOMAN) as part of Elliot's "farewell tour." A night not to be missed.
