Best time to visit Mongolia: a month-by-month guide

The best time to visit Mongolia is June to September, when the steppe is green, ger camps are open and roads to the Gobi and the lakes are passable. July is the busiest month because of the Naadam festival on 11–13 July. Winter, from roughly November to March, is extremely cold and suits only specialist trips.

Mongolia's climate in brief

Mongolia has a sharply continental climate: short warm summers and long, very cold winters, with big swings between day and night. UK government travel advice notes temperatures ranging from around +35°C in summer to −40°C in winter, and warns that weather can change quickly, with dust storms, heavy snow, blizzards and strong winds possible at any time of year. The most extreme conditions are in and around the Gobi and on the open steppe.

Because the country is so large and so high, conditions vary a lot between regions on the same day. The Gobi in the south is driest and can be hot in high summer; the forested north around Lake Khövsgöl is cooler and greener; and the far west, including Altai Tavan Bogd, is mountainous with a shorter season.

Mongolia month by month

Regional differences

The Gobi

The Gobi Desert is best from late May to September. Highlights such as the Khongoryn Els dunes, the Flaming Cliffs at Bayanzag and the gorge at Yolyn Am are reached on long overland drives, so dry weather matters. High summer days can be hot and nights cool.

Central Mongolia and Ulaanbaatar

Gorkhi-Terelj National Park, Khustai National Park and the old capital at Kharkhorin and Erdene Zuu are within reach of Ulaanbaatar and work well from June to September. The city itself can be visited year-round, but winter air pollution is a concern for anyone with respiratory conditions.

The north and the west

Lake Khövsgöl is at its best in July and August, when the water and forests are at their most inviting. In the far west, the season is shorter, and September is often favoured for clear skies and autumn colour.

Naadam and other events

Naadam is Mongolia's biggest festival. UNESCO, which inscribed it on its list of intangible cultural heritage in 2010, notes that it is celebrated across the country every year from 11 to 13 July, centred on wrestling, horse racing and archery. The opening ceremony in Ulaanbaatar is the headline event, while smaller local Naadams in the countryside offer a more intimate experience.

• Naadam: 11–13 July every year, with travel and hotel demand high either side of these dates.
• Tsagaan Sar (Lunar New Year): late winter, following the lunar calendar; a family celebration rather than a public show.
• Regional festivals in western Mongolia, including eagle-hunter gatherings in Bayan-Ölgii, are set locally each year; ask us for confirmed dates before planning around one.

Our Naadam Festival & Terelj package is built around the July dates and includes time in the national park.

What summer travel is really like

Even in the main season, Mongolia is a land of contrasts within a single day. Mornings in camp can be crisp, afternoons warm and dusty on the road, and evenings cool enough for the ger stove to be lit. Short, heavy summer showers can turn dirt tracks muddy and slow down long drives, which is why our itineraries leave slack in the schedule rather than packing in maximum distance.

Light is another reason to come in summer. Long days give time for sunset walks on the dunes at Khongoryn Els or a late horse ride near camp, and clear skies after dark make the steppe excellent for stargazing. In September, the low autumn sun and turning larch forests in the north are a favourite with photographers, though you trade a little warmth for that light.

• Pack a warm fleece or down layer, a windproof jacket and a hat, whatever the month.
• Bring sun protection: the high altitude and open landscapes mean strong sun.
• Sturdy shoes and a buff or scarf help on dusty Gobi days.

Crowds and prices

July is the peak month and the most expensive, especially around Naadam, when flights and Ulaanbaatar hotels fill early. June and late August to September offer good weather with more availability. Outside the summer season, many ger camps close and options shrink. See what a Mongolia trip costs for package prices and official fees.
