Sunny Daytime with Ample Sunshine

 

Throughout the month, the sun rises later and later from 07:33 to 07:48 and sets earlier and earlier from 20:18 to 19: 43, indicating gradually shortening daylight hours. In light of this situation, you are not recommended to plan a packed schedule, to prevent altitude sickness caused by high-intensity movements. 

Sunshine hours average long at 7 hours per day on average. During these 7 hours, the UV rays will be quite strong, especially during the period from 12:00 to 16:00. So, remember to always use sun protection items to protect your skin. At the same time, due to the long sunshine hours and strong sunshine, the climate of Lhasa will be relatively dry, even though the rainfall is not very low this month.
 

 Clothes: A short-sleeved T-shirt and a thin jacket, or a long-sleeved T-shirt alone, plus thin long pants are suitable during the daytime. Since it is relatively cold in the early morning and at night, take some warm clothes with you. In specific, you need to wear a T-shirt and sweatpants plus a thick jacket, like a windbreaker or a thick leather jacket. If Mt. Everest or Namtso is in your visiting list, make sure to bring a 3-in-1 jacket and long johns additionally to keep warm.

 Shoes: For a better and more comfortable travel experience, you are recommended to wear sneakers or hiking boots.

 Others:
