The peak tourist season in Mongolia is short, lasting from June until mid August. Thereafter, thunderstorms become more frequent and temperatures begin to drop. September sees more changeable weather and by October the snowline starts to creep inexorably downwards, engulfing the entire country from late December until the spring. In the depths of winter, travel is rendered all but impossible by freezing conditions, heavy snow and the total absence of accommodation outside the main towns and cities.
