Due to a death in the family, we are making plans to travel from Salt Lake City to Phoenix the second week of June for a memorial service. We will be traveling with an eight week old baby, and 2, 7, and 8-year-old children. Normally we wouldn't be traveling with the baby so young to such a hot temperament but it's something that we have to do. And as it's a drive that we can't do straight through because we'll have to nurse the baby every 2-4 hours and because we've never seen the grand canyon we decided to go ahead and make a vacation of the drive taking our time to get there.
Our itinerary: One night in Kanab UT (with stop at Cedar Breaks & Animal Sanctuary), one night North rim (scored a Western Cabin!), one night South Rim, two nights Sedona, four nights in Phoenix (with family) and two nights to get back home (we'll play those by ear - likely through Vegas).
I am expecting extremely high temperature while in Phoenix and we'll be indoors to keep the baby out of the heat. I was thinking that our other stops would also be extremely hot but was surprised when looking at average temperatures that highs in June at Grand Canyon (North rim cooler) and Sedona are in the 80's to 90's. While I'll consult with the pediatrician on heat safety for the baby (she's tiny - not even 8 pounds yet) I wanted to get an idea of what I can reasonably expect. I understand that a heat wave can come through and throw those temps up to the 100's. Daytime and evening temperatures for North and South Rims and Sedona? Will it get chilly enough in the evening (north rim?) to warrant a light jacket or is that overpacking?
Thank you so much for your insight from those who are familiar with the region! So appreciated.
