The short answer
When to go to Tso Moriri
July and August are the only months with reliably clear, stable weather; June and September are possible but cooler and wetter, with less predictable conditions. The road is closed by snow from November to April, so travel is only realistic in a narrow summer-to-early-autumn window. At 4,522 metres, Tso Moriri is high enough to cause altitude sickness in unacclimatised travellers, so spend at least a full day in Leh beforehand and consult a doctor if you have heart or respiratory concerns; there is no medical facility at the lake itself.
