Humidity cant be below zero, it measure how much water is in the air.

Doesn’t SoCal sometimes have negative humidity? 20% seems pretty high to say it works in the desert.

I think technically what we call humidity is actually relative humidity, so it can go below zero. Ture humidity can’t of course.

It really comes down to what you mean by humidity. “Dew point” can be negative, but humidity cannot.
“Negative humidity” is like saying “this glass has so little water in it, it has negative water”.
