Yeah ... I just checked, knew that figure was BS. It’s gotta be a typo.
19% (Not 91%) is right in line with typical daytime humidity for July in Death Valley. It might crack 50% or so at night, in the winter months. 118° F. and 91% humidity is just short of Sous Vide. Ain’t gonna happen in Death Valley.
Yes, I believe you are right.
And 19% humidity at 118 degree air temp would make anyone prefer Hell.
