Kharkhorin in February

Summer transforms this harsh landscape into something almost gentle. June through September offers the warmest weather, with July and August hitting pleasant 20-25°C during the day. But nights still drop to near-freezing even in summer — pack layers. June brings wildflowers to the steppe and fewer crowds than peak July-August. September offers crisp, clear days perfect for photography, though nights turn properly cold. Avoid winter unless you're prepared for -30°C temperatures and limited services. Spring arrives late and muddy. The Naadam festival in July brings extra activity to the region, but book accommodation well ahead. Weather changes fast here — afternoon thunderstorms appear from nowhere.
