Grand Canyon in July: what the park service says

July starts Grand Canyon's monsoon: the park says thunderstorms are frequent in July, August and early September, mostly between 11 a.m. and 6 p.m., bringing torrential rain, lightning and sudden flash floods. South Rim highs are usually in the 80s°F, while the river near Phantom Ranch passes 100. Floodwater can reach the canyon bottom without warning, so avoid narrow side canyons when storms build.
