The term “Santa Ana” for the winds is apparently folk etymology. I read somewhere it was originally “santana” meaning “devil’s breath,” which makes sense since it is hot wind coming from the desert.

Thanks, Interesting observation how terms can morph overtime, but I thought the term came from the Santa Ana Canyon in Orange County, Ca. Whatever, it truly feels like the devil’s breath blowing on you - dry and hot. Your post prompted me to find this article - https://people.atmos.ucla.edu/fovell/LATimes_SantaAna.html

Thanks for posting the link to that article. So the "santana" theory may be wrong too.

The article has one error: St. Anne's day is July 26, not July 25. July 25 is the feast of St. James.
