My guess is that Arizona is very hot, dry, arid etc....
I would get some shade cloth, misters & a swamp cooler pronto!

We have just relocated from Forida to Phoenix, and are managing to
adjust. However, the orchids are not doing so well. We kept them on
the patio of our Florida home, and they seemed to thrive.

We have them in a similar location here in Phoenix, and they are not
doing so well - from my inexperienced eye, I'd say they are looking
awfully yellowish. Does anyone have any suggestions on raising
orchids in an arid environment?

Thanks,
