Got it, KD. Our weather has turned cooler the last week, but that simply reflects the air temperature and humidity levels are lower because of a cold front moving through and high pressure sitting on top of us. The intensity of the sun's rays won't change a bit though, since we are generally clear with very little cloud cover. The humidity is beginning to creep back up, getting close to our usual 70+ relative humidity and by mid-week, we are back into more typical heat, with highs in the mid-90's. I would think that my adeniums' leaves react to the sun rather than to temperature/humidity, but I could be completely off-base with that assumption.
