The southern part is. Further north, it's classified as a Mediterranean climate. I'd suggest the western side is a desert as well. It's only possible to grow crops there by importing water from the northern part of the state. With out that water, it would look like dry mountains to the immediate west along I-5. It only averages a few inches of rain per year.
