absolutlely NOT
you get there in December and leave in early April.
unless you like to stay in Air Conditioned rooms your whole stay.
I will go there this coming winter though.
Grand Canyon is coolish year round. Visit Flagstaff instead of Tucson if you’re a northerner and can’t stand the heat.
As a year-long resident of Arizona and one who lives off the grid (no electric appliances like air conditioning) I can testify that wimps who avoid the Grand Canyon State in the summer are, in fact, wimps. Heck, we don’t ever use the ac in our automobile. Harry Truman was right, if you can’t stand the heat, stay out of the kitchen. Just gives the rest of us that much more ‘personal space’.
