Right you are. When we were in Gastonia a few years back, my complexion was in marvelous condition because of the humidity. My hair, on the other hand, was so frizzy! On our way back home to CA, my skin started getting drier and drier. The thing with humidity is that you just cannot seem to dry off after a shower. You also have to contend with mold and mildew. I have never had any mold or mildew on my clothes since I have been in CA (over 40 years), but in the South, you had to be careful with laundry. But out here, we don't really have four seasons. That is what I miss most of all. Thinking of your mom.
It depends on your elevation. Summer temps usually top out in the mid 80s at our house. It is rare for us to hit 90, I only remember it happening a few of times in 14 years here. With all the tree cover, we only get a couple of hours of sunlight on our house. Summer lows are usually in the low 60s. It can get humid but as bad as Gastonia.
