So how about going up the Pacific coast? How would it be in mid-May if we go all the way to the top of Oregon? Then, check out Oregon, then maybe Nevada and Utah on the way back to AZ? Would we likely find moderate weather on that routing?
This would be the ideal route for your trip. By the time you get to Utah on your return the weather will be perfect.
Also, May would be good for the South Rim of Grand Canyon and for Zion if you wanted to do those on your way out of Arizona and up the coast.
One of our times at the Grand Canyon was in February and the weather was great. You never know. Just monitor the weather as you travel.
We always started heading north out of Arizona in April/May. May in Arizona is getting hot. We did travel slowly though.
