I live in AZ. As others have said, get up early & get your riding done before noon. It doesn't cool off enough in the evening to plan on riding then even if you don't mind riding in the dark - it will still be 100 degrees at midnite. I don't like riding when I can't see but don't mind starting 1/2 hour or so before daybreak. Starting at 4:30 gives you a good 7 hours to ride. Motels here will be empty that time of year & won't mind you checking in early. But some AZ motels & restaurants are seasonal, open only during snowbird season. So be sure to call ahead and make sure the places you plan to stay & eat will be open.
