At the end of July 2009, I went to Lhasa next week. What's the weather like? How to get dressed?

In fact, Lhasa is hot or warm where the sun shines all year round, and cold or cold where there is no sun. Now it is generally 10 to 20 degrees. I suggest you wear short sleeves or long sleeves, and then wear a thin coat. This should be more suitable. In addition, you'd better do enough moisturizing and sunscreen work. SPF30 or above.
