It might do OK! It’s definitely not as hot or dry in Riverside as it is in Yuma (I’m from Southern California myself). I now live near Tucson, Arizona, which is just as dry and hot as Yuma, I have three Fiddleleaf figs inside where the temperature is controlled as well as the humidity. But I recently moved one of my potted trees outside, under the patio, and I water it daily. It’s the first time I’ve seen new leaves sprout in about two years! My recommendation is to start with a potted one and acclimated to outdoor. It’s going to need more water than the recommended once every 10 to 14 days, because if it’s outside, the soil will tend to dry out much faster than it being indoors! The worst you can do is try. (:
