Xinjiang is vast—at 1.6 million square kilometers, it accounts for roughly one-sixth of China's total land area. This sheer size means the region contains multiple climate zones packed into a single province. The climate of Xinjiang is broadly classified as temperate continental, but the reality on the ground varies dramatically depending on whether you are in the Altay mountains in the far north, the Taklamakan Desert in the south, or the Ili Valley in the west.
Understanding Xinjiang's weather patterns month by month is essential for planning a trip that matches your interests. A visit timed for the lavender bloom in June will look completely different from a September road trip through golden poplar forests or a February ski vacation in Altay. This guide breaks down every month with real temperature data, precipitation patterns, daylight hours, and the activities each season rewards.
Before diving into monthly details, it helps to understand the three major climate regions. The Tianshan mountain range divides Xinjiang into two distinct halves, each with its own weather personality.
Northern Xinjiang (Beijiang) includes Urumqi, Altay, Kanas Lake, and the Ili Valley. This region is influenced by cold Siberian air masses and receives more precipitation—roughly 200–500mm annually depending on location. Winters are long and harsh, summers are warm but moderate, and the growing season is relatively short. The Ili Valley is the exception, receiving enough moisture to support lush grasslands and even lavender fields.
Southern Xinjiang (Nanjiang) covers Kashgar, Hotan, Kuqa, and the Taklamakan Desert basin. This area is drier and warmer, sheltered from northern cold fronts by the Tianshan. Kashgar's winters are tolerable, and summers can be intensely hot, especially in low-elevation areas like Turpan. The Kunlun Mountains form the southern boundary, creating a rain shadow that makes the desert interior extraordinarily arid.
The Tianshan Mountains themselves form a third zone, with alpine conditions above 3,000 meters. This is where you find the dramatic Duku Highway, the Tianchi Lake near Urumqi, and high-altitude grasslands like Nalati and Bayanbulak. Weather in the mountains can change within hours and temperatures drop sharply with elevation.
Temperature: Urumqi averages -12°C to -8°C. Altay plunges to -25°C or lower. Kashgar hovers around -5°C to 2°C.
Precipitation: Light snowfall in the north, roughly 5–10mm. Southern Xinjiang is essentially dry.
Daylight: About 9 hours of daylight. Sunset falls around 6:30 PM local time (though Xinjiang officially uses Beijing time, the sun sets roughly two hours later than it does on the east coast).
Highlights: Altay has emerged as China's rising ski destination, with powder snow that rivals Hokkaido in quality. The General Mountain ski area near Altay city and the newer Jikepulin resort offer terrain for all levels. In Kashgar's Old City, winter means fewer tourists and a chance to experience Uyghur daily life without the summer crowds.
Packing: Thermal base layers rated to -30°C, insulated boots, hand and toe warmers, a balaclava, and ski goggles if heading to Altay.
Temperature: Urumqi: -10°C to -4°C. Altay: -20°C to -10°C. Kashgar: -3°C to 5°C.
Precipitation: Similar to January, light snow in the north.
Daylight: Increasing to about 10.5 hours by month's end.
Highlights: Chinese New Year (late January or February) brings festive energy to cities. Hotan's jade markets are active year-round but feel more intimate in winter. This is also an excellent time for winter travel in Xinjiang if you want solitude at major sites.
Packing: Same heavy winter gear as January, but you can start layering lighter in southern Xinjiang.
Temperature: Urumqi: -2°C to 8°C. Altay: -8°C to 3°C. Kashgar: 3°C to 14°C.
Precipitation: Increasing slightly, 10–15mm. Wind picks up, especially in the Dzungarian Basin and along the Turpan corridor.
Daylight: 12 hours by the equinox.
Highlights: March is transitional and unpredictable. Snow melts at lower elevations while mountain passes remain closed. The Turpan area warms first, and almond blossoms begin appearing in the valleys around mid-March. The Duku Highway remains closed—it typically opens in June.
Packing: Layers are essential. Warm jacket, windbreaker, waterproof boots for slush in northern cities.
Temperature: Urumqi: 8°C to 18°C. Altay: 2°C to 14°C. Kashgar: 10°C to 22°C.
Precipitation: 15–25mm, with occasional spring showers in the Ili Valley.
Daylight: 13–14 hours.
Highlights: This is the season for wildflowers. The apricot blossoms of the Ili Valley (especially around Xinyuan County) bloom in early to mid-April, painting hillsides in pink and white. Turpan's grape vines begin leafing out. Kashgar's Sunday Grand Bazaar picks up energy as farmers bring spring produce. For planning your overall trip timing, our Xinjiang best time to visit guide covers the broader picture.
Packing: Light jacket and fleece for evenings, T-shirts for sunny afternoons. Sunscreen becomes important as UV intensity rises.
Temperature: Urumqi: 14°C to 26°C. Altay: 8°C to 22°C. Kashgar: 16°C to 28°C.
Precipitation: 20–35mm, mostly in the north. The Ili Valley can see scattered showers.
Daylight: 14.5–15 hours, with sunset around 9:30 PM local solar time.
Highlights: May is a sweet spot for travelers who want warm weather without summer's heat or crowds. The Nalati and Bayanbulak grasslands turn green, though the grass has not yet reached full height. Sayram Lake thaws and reflects snowcapped peaks. This is also a good month for planning a multi-week Xinjiang itinerary that covers both northern and southern routes.
Packing: Light layers, a warm jacket for mountain evenings, comfortable hiking shoes.
Temperature: Urumqi: 18°C to 30°C. Altay: 12°C to 26°C. Kashgar: 20°C to 33°C. Turpan: 25°C to 38°C.
Precipitation: 25–45mm in the north. The Ili Valley sees its wettest month, which keeps the grasslands vivid green.
Daylight: Up to 15.5 hours at the summer solstice, with usable light until nearly 10:30 PM.
Highlights: Lavender season in Huocheng County peaks in the last week of June—this is Xinjiang's Provence. The Duku Highway typically opens in mid-to-late June, unleashing the flood of road trippers who have waited all winter (see our complete Duku Highway guide for details). Sayram Lake is at its most photogenic. Wildflower meadows on the Tianshan slopes are in full bloom.
Packing: T-shirts and shorts for cities, but bring a warm layer and rain jacket for mountain areas. High-altitude UV is intense—SPF 50 sunscreen and sunglasses are non-negotiable.
Temperature: Urumqi: 22°C to 33°C. Altay: 15°C to 28°C. Kashgar: 23°C to 36°C. Turpan: 30°C to 42°C.
Precipitation: 20–35mm, with occasional thunderstorms in mountain areas.
Daylight: 15 hours at the start, decreasing to 14.5 by month's end.
Highlights: This is peak domestic tourist season. The grasslands of Nalati, Bayanbulak, and Tangbula are at their lushest, with Kazakh herders setting up their summer yurts. The Karakoram Highway is fully accessible. Turpan is brutally hot—the Flaming Mountains regularly exceed 45°C at the surface—but that heat is part of the experience. Grape harvesting begins in late July. For road trip enthusiasts, our self-driving Xinjiang guide covers practical details for summer driving.
Packing: Light, breathable clothing. Wide-brimmed hat and sun protection. Swimwear for Sayram Lake. A fleece for high-altitude camping.
Temperature: Urumqi: 20°C to 31°C. Altay: 13°C to 26°C. Kashgar: 20°C to 34°C. Turpan: 28°C to 40°C.
Precipitation: 15–25mm, generally drier than July.
Daylight: 13.5–14.5 hours.
Highlights: August brings the first hints of autumn in the north. Altay's birch forests start turning gold by late August. The Turpan Grape Festival typically runs in mid-to-late August, celebrating the region's famous seedless grapes and raisins. Melon season is at its peak—Hami melons from the town of Hami are extraordinarily sweet in August. Tourist crowds begin thinning after mid-August when Chinese schools resume.
Packing: Similar to July. Start bringing a warmer jacket for northern Xinjiang evenings.
Temperature: Urumqi: 12°C to 23°C. Altay: 5°C to 18°C. Kashgar: 12°C to 26°C.
Precipitation: 10–18mm. Mostly clear skies.
Daylight: 12–13 hours, with the autumn equinox around September 22.
Highlights: September is Xinjiang's finest month for travel. Kanas Lake and Hemu Village explode into color—golden birch, orange larch, and deep green spruce against turquoise lakes and snow-dusted peaks. The weather is stable, dry, and comfortable for hiking. The Karakoram Highway is still open and the Pamir Plateau is accessible. Apple harvest festivals in Aksu and Korla add cultural flavor. For those chasing peak foliage, our Xinjiang autumn colors guide pinpoints the best weeks.
Packing: Layered clothing. Warm jacket for mornings and evenings, T-shirts for midday. Camera gear—this is peak photography season.
Temperature: Urumqi: 3°C to 14°C. Altay: -5°C to 8°C. Kashgar: 5°C to 18°C.
Precipitation: 5–12mm. Very dry.
Daylight: 10.5–12 hours.
Highlights: Early October (National Day holiday, October 1–7) brings a surge of domestic tourists to Kanas and Hemu. After the holiday, crowds vanish and prices drop. The poplar forests along the Tarim River turn brilliant gold. Southern Xinjiang remains comfortable for travel well into late October. The Duku Highway usually closes by mid-October due to snow.
Packing: Warm layers, insulated jacket, hat, and gloves, especially for northern Xinjiang. Southern routes remain mild enough for lighter layers.
Temperature: Urumqi: -5°C to 3°C. Altay: -15°C to -3°C. Kashgar: -2°C to 10°C.
Precipitation: 5–10mm, mostly light snow in the north.
Daylight: 9.5–10.5 hours.
Highlights: The tourist season is effectively over in northern Xinjiang. Hotels in Kanas and Hemu close for winter. Kashgar and Hotan remain accessible, with quieter bazaars and a more local atmosphere. This is the time to experience Uyghur culture without the tour groups. The desert landscapes around the Taklamakan take on a stark, haunting beauty under winter light.
Packing: Full winter gear for the north. Moderate winter wear for southern Xinjiang.
Temperature: Urumqi: -12°C to -5°C. Altay: -25°C to -12°C. Kashgar: -5°C to 3°C.
Precipitation: 5–8mm, light snow.
Daylight: About 9 hours, the shortest days of the year.
Highlights: Ski season begins in earnest at Altay's resorts. The Kashgar Sunday Bazaar continues year-round, and the Id Kah Mosque is especially atmospheric in winter light. If you are considering a December visit, focus on southern Xinjiang for cultural exploration or northern Xinjiang for skiing.
Packing: Maximum insulation. Down jacket rated to -30°C, insulated boots, thermal everything.

The divide between northern and southern Xinjiang is not just geographical—it fundamentally shapes what you will experience as a traveler. The Tianshan Mountains act as a massive climatic barrier, blocking both Arctic cold from reaching the south and desert heat from reaching the north.
Winter temperature gap: In January, the average temperature difference between Urumqi (north) and Kashgar (south) is roughly 7–10°C. That is the difference between a manageable cold and a dangerous one. Kashgar's winter feels like a cold autumn day in northern Europe, while Altay's winter feels like the interior of Alaska.
Summer heat distribution: Southern Xinjiang's Turpan Depression regularly records the highest temperatures in China, with air temperatures exceeding 45°C and ground temperatures above 70°C near the Flaming Mountains. Meanwhile, Bayanbulak Grassland at 2,500 meters elevation can see nighttime temperatures drop to 5°C even in July—a 40-degree swing within a few hundred kilometers.
Precipitation patterns: The Ili Valley in western northern Xinjiang is the province's wettest region, receiving 300–500mm annually thanks to moisture carried by westerly winds from the Atlantic and Arctic. This is why Ili supports lavender fields, dense forests, and lush grasslands. The Taklamakan Desert in southern Xinjiang receives less than 20mm per year—some weather stations have recorded years with zero measurable precipitation.
For travelers planning a comprehensive trip that covers both regions, timing is critical. If you want to combine Kanas autumn colors with Kashgar cultural exploration, late September is the narrow window when both regions are at their best.
