Areas with heavy swells seem to be particularly vulnerable.

I can remember some huge 30' swells in the Pacific with
a period of 2 minutes. I'd think big swells near a place like
Sable Island and or the Gulf Stream could produce rogue
waves.

There must be some sort of seasonal incidence of rogue
wave.

I was unable to find a plot of the locations of mysteriously
lost ships worldwide. I saw one a few years ago online.
