Yili weather has always been renowned for its variability and charm. Located in the northwest of Xinjiang, China, this land lies at the northern foot of the Tianshan Mountains. Its unique geographical environment has created a climatic landscape distinctly different from other parts of Xinjiang. Unlike the arid and hot southern Xinjiang, Yili, relying on the melting snow from the Tianshan Mountains and the moisture of the river valley, has become a “wet island” in the northwest borderland. With the rotation of the four seasons, every change in the weather paints the grasslands, lakes, and snow-capped mountains with unique colors. For foreign travelers planning to visit here, grasping the patterns of Yili weather not only ensures a smoother journey but also allows them to accurately capture the most charming scenery of each season.
Getting to Know Yili: The Profound Connection Between Geography and Weather
To understand the uniqueness of Yili weather, one must first start with its geographical location. The Ili Kazak Autonomous Prefecture is situated in the western section of the Tianshan Mountains, with various landforms such as the Ili River Valley and the southwestern edge of the Junggar Basin distributed within its borders. The Tianshan Mountains act as a huge barrier, blocking the cold air from Siberia and the dry air currents moving south from the deserts. Meanwhile, the river valley area is conducive to the penetration of warm and humid air currents from the Atlantic Ocean. This gives Yili a “mild and humid” climate, forming a sharp contrast with the Xinjiang that people imagine as a “gobi desert.”
Yili’s climate belongs to the temperate continental climate, but it also has distinct mountain climate characteristics due to the influence of terrain. Simply put, the annual and daily temperature ranges here are relatively small, with precipitation concentrated in summer. Moreover, the climate varies greatly across different regions — the river valley plains are warm and humid, while the mountainous areas are cool and windy, and snow can even be seen in summer. This three-dimensional climate feature means that even when visiting Yili at the same time, the weather at different scenic spots may be completely different, which is something foreign travelers need to pay special attention to.

Spring in Yili: Melting Snow and Blossoming Flowers Everywhere
The weather in Yili during spring (from March to May) can be described as “gradually entering the best state.” During this period, the land undergoes a magnificent transformation from severe winter to warm spring. In early March, Yili still retains the lingering cold of winter. The average temperature in the river valley area ranges from 0°C to 5°C, and the mountainous areas remain below zero. At this time, the grasslands have not yet revived, but it is an excellent opportunity to appreciate the melting snow in the snow-capped mountains. With the arrival of April, the temperature gradually rises to 10°C to 20°C, and the apricot blossoms in the Ili River Valley begin to bloom in a riot of colors. Especially in the Tuergen Apricot Blossom Valley, tens of thousands of acres of wild apricot blossoms cover the hillsides. Under the warm spring sun, the pink and white sea of flowers contrasts beautifully with the distant snow-capped mountains, becoming the most charming scenery of Yili in spring.
The most prominent feature of Yili weather in spring is the large temperature difference between day and night. It is warm and comfortable during the day when the sun is shining, but the temperature drops sharply by more than 10°C in the evening. Therefore, foreign travelers need to prepare layered clothing such as long-sleeved jackets and thin sweaters. In addition, spring is also the windy season in Yili, with occasional sandstorms. It is recommended to bring windproof goggles and masks. In late May, the grasslands begin to take on a tender green color. The rivers on the Bayinbulak Grassland gradually thaw, and the weather becomes more stable, with an average temperature between 15°C and 25°C, making it an ideal starting point for a grassland journey.
Summer in Yili: Cool and Pleasant, A Feast on the Grasslands
Summer in Yili, from June to August, is the peak tourist season, and Yili weather also enters its most comfortable stage during this time. Due to its location in the plateau river valley, Yili does not experience the sweltering heat of inland cities in summer. The average temperature in the river valley plains ranges from 20°C to 28°C, and it is even cooler in the mountainous areas, only 15°C to 22°C, truly living up to its reputation as a “summer resort.” During this period, precipitation in Yili is relatively concentrated, mostly in the form of short showers. After the rain, the air becomes extremely fresh, and sometimes a gorgeous rainbow can be seen spanning the grasslands.

It should be noted that the weather in the mountainous areas changes rapidly. Even on a sunny morning, the temperature may drop suddenly and it may rain. Therefore, when foreign travelers go to mountainous scenic spots such as Nalati and Karajun, they must bring windproof and waterproof jackets and thin down jackets. In addition, the daylight hours in Yili are very long in summer.
