The exact date is rarely confirmed until shortly beforehand, but Tibet ‘reopens’ to foreign visitors in early April, following a six-week period when borders are closed and travel visas unavailable. Like March, April in Tibet is sunny and dry, but also cold and windy, especially in the higher reaches. April is a great time of year to travel in Tibet, as the mountain scenery is outstanding, and the peak summer season is still a way off.
Average daytime temperatures in Tibet during April range from 1°C to 16°C, but drop precipitously at night, so layering with thermal clothing is a good idea. There is still the possibility of travel disruption due to the effects of melting snow: even Namtso Lake at an elevation of 4700m is typically beginning to thaw at this time.
The climbing season begins in Everest National Park from April onwards, but even if you’re only there to take in the views, expect to be wowed. April is also an excellent time of year for trekking around the iconic Mount Kailash in the southwest. Tibet’s diverse landscapes still have a magical wintery aspect to them, and the bright colours of prayer flags and traditional clothing are at their most vibrant under the springtime sun.
