The temperature variation is significant, but it's the combination of wide temperature swings with dry, dry Arizona air that's causing the wood to crack.

Wood is especially vulnerable when it transitions suddenly from a very damp environment to a very dry one.  I believe you said that you're based now in the Phillipines?
