September weather forecast
Mongolia

September ushers in the autumn season in Mongolia, a period marked by crisp air, cooler temperatures, and changing landscapes. In the northern and central regions, including Ulaanbaatar, temperatures generally fluctuate between 10°C (50°F) and 20°C (68°F). The southern regions and the Gobi Desert experience a wider range of temperatures, typically between 15°C (59°F) to 25°C (77°F) during the day and dropping sharply at night.

The change in season is accompanied by a significant decrease in rainfall, making September one of the drier months of the year. The likelihood of rain is low, and the weather is predominantly dry and clear. This reduction in precipitation coupled with the dropping temperatures results in the foliage starting to change color, painting the landscapes in beautiful autumn hues.

Wind conditions in September are generally calm, but occasional gusts can occur. The winds, combined with the falling temperatures, can create a noticeable chill in the air, especially during the evenings and nights.

As September transitions into October, temperatures continue to drop, and the landscapes further transform, heralding the approach of the harsh Mongolian winter. Despite the onset of cooler conditions, the clear skies and beautiful autumn colors make September an excellent time to visit. Therefore, September serves as the gateway to autumn, marking the transition from the warmth of summer to the cooler and drier conditions that characterize the fall season.
