What's the weather like in Meili Snow Mountain and Shangri-La from mid-June to early July?

Just got back from Yunlijiang: short sleeves and trousers are the best, and you must wear sneakers, because there are washboards everywhere; Three days is not sunny, but ten miles is different. You must take an umbrella, rain or shine. Shangri-la has coats and oxygen cylinders rented locally. It's hard to take a bus, 5-6 hours, and there is water and food on the road. It is best to fly directly to Lijiang, and then radiate to the other three places from there. Kunming is not fun, too far away and too tired.
