What May feels like
The North Rim opens around the middle of the month and it is a different park up there — higher, quieter, and worth the long drive around. Down at the river the heat is already building, so rim-to-river day hikes are in the last of their comfortable weeks.
Real rain shows up maybe one day all month; the rest stay dry. about 9 nights dip below freezing.
