Weather: August is a pleasant time to tour Jiuzhaigou, and you won’t feel cold unless it rains. The weather is quite comfortable. You can almost get a sense for all of the seasons of the year in August as you travel up the valleys thousands of feet. Like the previous several months, the temperature differences are still great—warm during the day and cool during the night.
Average daily low and high temperatures are 14 °C (57 °F) and 26 °C (79 °F) in August. There is about 95 mm (3.7 inches) of total rainfall each August, and precipitation falls on about 16 days of the month. The ultraviolet index index is extreme. See the current weather and forecast>>
Clothing: Wear a long-sleeve shirt and trousers to protect your skin. Sunglasses and a sunhat will help for hiking on a sunny day. Make sure that your shoes have good traction when you hike and bring a waterproof poncho in case it rains.
Altitude Sickness: Most visitors experience altitude sickness during an overnight stay or two day stay because most of the park lies between 2,000 meters (6,561 feet) and 3,000 meters (9,800 feet). The airport is at an elevation of 3,500 meters. To avoid overexertion, we suggest you walk downhill to see the highlights. Take precautions if you have heart disease or high blood pressure.
See Rize Valley: In August, you can take a summer hike in the upper altitude valley of Rize that is above 2,400 meters. It is about 18 kilometers (11 miles) long. There are colorful carbonate pools. Rize is the upper right fork of the Y-shaped Jiuzhaigou valleys. It is more scenic than its twin valley called Zechawa Valley, and we recommend it. You can start at the top of Rize Valley and hike down to Nourilang Falls near the junction of Rize and Zechawa Valley.
Nourilang Falls is at the bottom of Rize Valley at an elevation of 2,300 meters or 7,700 feet. It is big, 80 feet high and 300 meters wide, and it is one of the main sites in the valley. Since the Chinese crowds don't generally walk between the popular attractions, you can enjoy the walk to Nourilang without a lot of crowds.
Shuzheng Valley: Shuzheng Valley is the lowest valley, and it is 14 kilometers (9 miles) in length. There are many plank walkways that you can use to see the ponds. Bonsai Beach, Reed Lake, and Rhinoceros Lake are major attractions. But be careful because it might be slippery. Wear shoes with good traction.
Enjoy Huanglong Valley: Huanglong is a major highlight that is about 4 hours away though it is only 50 km in a straight line. It is a UNESCO Heritage site and nature preserve. It is less visited than Juizhaigou, and most people think it is more beautiful. In August, temperatures range between 3 °C (36 °F) at night and a pleasant 16 °C (61 °F) during the day. Since there are no park buses, but you can walk and enjoy the scenery of hundreds of multicolored ponds. Danyun Gorge is a beautiful side valley with a dense forest.
August is a moderately high tourist month, so hotel room rates are higher than in the winter. The prices for flight and train tickets are higher than in the winter. The busy tourist season starts in the fall, so you can enjoy the beauty and the warm temperatures before the prices rise in September and the large crowds arrive.
Consider a Jiuzhaigou combo package tour. A tour of Jiuzhaigou or Huanglong is combined with major regional attractions such as a Yangtze River tour.
