Chasing 75 degree weather all year? Need some input

Since one of you're prerequisites is "low humidity" , that ends the conversation right there. You simply will not come anywhere near a constant 72, or anything else by removing yourself from the coast.

Where did I say I wanted to avoid the coast? Just because something is near a coast doesn't raise its perceived/relative humidity. In fact, because of the winds, humidity is often "felt" to be lower.
Include the west COAST, and carry on!
