Yes, we are in sunny warm Arizona, but... we have had some some very cold nights. It was about 28 this morning and our water hose was frozen for a little while. It didn't take long and the water was running again and the day warmed up to around 60. You can see the sky was still clear and the sun was shining, but brrrrr, it was cold. They are predicting we will be back to 80 degrees by Monday.
