What is the approximate temperature in June along National Highway 318?

The temperature between Shanghai and Ya'an is about 30 degrees, maybe a little higher. The temperature in the Erlang Mountain area drops by about 3 degrees. After crossing Zheduo Mountain, it is about 22-30 degrees. It will be a little colder at night. , for every 1000 meters of altitude increase, the temperature drops by 6 degrees. In the same weather, the difference between Zheduo Mountain Pass and Xinduqiao can be 4-5 degrees. The temperature difference between day and night, sunny, cloudy, rainy and snowy days, wind speed should be considered, and thin cotton clothes should be prepared. , cardigans should be prepared, and short-sleeved T-shirts should be prepared.

Hope to adopt
