Grand Teton in July: what the park service says

July is Grand Teton's warmest month, averaging about 81°F by day at Moose but only around 42°F at night, so pack layers. Afternoon thundershowers are common, and in the mountains storms can arrive without warning, bringing lightning, rain and hail to the peaks. Snow often lingers in the high country until mid-July, so check trail and avalanche conditions first. The park recommends raingear in spring, summer and fall, as mild days and sudden storms can alternate quickly in Jackson Hole.
