One of the best months to travel to Tibet is the month of June as the early weeks of this month are still warm and dry. Heavy monsoon, however, usually starts on the third week of June. Yet, despite the onset of heavy monsoon, you can still enjoy the famous hiking route of Tibet during daytime, such as Mt. Kailash trek, Ganden Samye trek, Tinger to Everest Base Camp trek, etc. because rain usually falls during nighttime. Tibet’s temperature may fluctuate from a minimum of 9 °C during nighttime to a maximum of 24 °C during daytime. The average June Temperature is at 17 °C with an average precipitation of 63mm, and 8 wet days on average. Additionally, the average relative humidity in Tibet during June is 64.
