Climate: Tibetan winters, as might be supposed, are fiercely cold. But for half the year, strong sunlight warms the thin air, making most days in Lhasa comfortably mild and, owing to protective mountains, relatively windless. Summer temperatures hover above 30'C (high-80s F) and only to drop to a searing -23'C (-10'F) in midwinter. The best time to visit is from late spring to early fall.
