January climate brief introduction:
April is the first month of spring in Tibet. The daytime gets longer and it continues to warm up in whole Tibet plateau.Trees leaves begin to sprout fast and some of the trees in Lhasa become green.

What to wear in April?
For comfort in the changing temperatures and high UV radiation, you'll need to dress in layers and cover up if you are in the sun for a prolonged time due to the UV radiation. Many hotels and restaurants in Tibet have no central heating, so you might still need a coat inside. But the sunshine is so strong that you might feel comfortable in light clothing during the day. Have a T-shirt, coat, trousers, and a sun hat in Lhasa, and a heavy coat and gloves for higher places. Sunglasses can protect your eyes.
What do to in April?
Lhasa (3650 meters) The holy city Lhasa is famous for its beautiful landscapes, thousand-years-old history, unique Tibeatan culture, sunshine & blue sky and friendly local people. The most outstanding highlight is its magnificent palace and temples, such as the famous Polata Palace, Jokhang Temple, Barkhor Street, Drepung Monastery, Sera Monastery, and Norbulingka.
Shigatse & Tsedang: Travel is fine for these two high altitude towns in southern Tibet. But it is a good idea to acclimate. Shigatse is notable because it is Tibet's second largest city, on the road to Everest (7 hours away) and west Tibet, a place for acclimation. Tsetang is Tibet's third largest place, with Samye Monastery, Yambugalang Place, and Yamdrok Lake as notable attractions.
Namtso Lake: You can start to go to other places near Lhasa that are inaccessible in the winter. It is quite a contrast to leave spring in the Lhasa valley and go north to Namtso Lake. It takes four hours to get there over a pass of 5,200 meters. There might be beautiful winter scenery in April because the lake is likely still frozen until late April when it turns an amazing turquoise or deep blue color.
Mt. Everest Base Camp: March and April are two of the best months for best time to visit Mt. Everest. It is when most climbing teams start their climb before the weather turns snowy in May. The weather is clearer, so you have a chance of seeing it as you hike around Everest Base Camp.
The comfortable travel weather, the variety of scenery, and the less crowds and rainfall than in the tourist high season are reasons that April is probably the best month to go to Lhasa if you want some serenity, low prices, great scenery, and good selection for accomodations and travel opportunities. Tourists flood in between the end of April and early October.
