I just finished hiking from the Mex border to Flagstaff. Beautiful hiking weather except for 3 seperate nights of snow and 20ish temps. Woke up one morning with two frozen water bottles in my tent. Otherwise day temps around 75 and nights about 40. Overall water supplies were excellent. Pretty much anything rate w1 or better had water. Occasionally you’d find snow melt on the north sides of peaks and a creek or two flowing that weren’t mentioned in the guide or trail data.
