When to go & weather

Weather

Weather can be extremely temperamental in the Altai mountains. Brief snowstorms are common even in summer. These don’t last long; usually within an hour the sun will be out again, but have a jacket ready. Summer is surprisingly cool in the Altai Mountains and you’ll need a reliable, sub-zero rated sleeping bag and tent. The low-lying lakes and rivers of western Mongolia also attract some appalling packs of mosquitoes; arm yourself with serious bug repellent.
