What August feels like
August is the wettest month here and the forest gets green in a way that surprises anyone who thinks of Arizona as brown. Lightning is the honest risk: nobody local is above treeline on Humphreys after noon in August, and you should not be either.
Rain arrives about 7 days of the month, so keep one flexible day in your plans.
