The Short Answer
Best overall: Mid-September to early October. The weather is perfect, the crowds have left, and the autumn colors in the grasslands and birch forests are spectacular.
Best for budget travelers: April-May and November-March (excluding peak holiday weeks).
Best for photographers: September-October (colors) and January-February (snow).

Now here’s the month-by-month breakdown.
Month-by-Month
March
Weather: -5°C to 10°C. Still winter in most of Xinjiang.

What’s closed: High mountain passes (Muztagh Ata area, some grassland areas).
April
Weather: 5°C to 20°C. Spring arrives in the south (Kashgar, Turpan).
Why go: Apricot blossom season in Kashgar region. The old city is magical with flowers in the courtyards.
Crowds: Still very few. This is the “secret season” that locals know about.
May
Weather: 10°C to 25°C. Pleasant across most of the region.
Why go: Everything is open, but the summer crowds haven’t arrived yet. Great for the Ili Valley grasslands (they’re green but not yet dried out).

Crowds: Still peak. Book everything 2-3 weeks ahead.
September
Weather: 10°C to 25°C. The best month.
Why go: Autumn colors start in the north (Kanas, Hemu). The heat backs off. Crowds leave after September 10.
This is the month: If you can only pick one, make it September.
October

Why go: Kanas and the birch forests are at peak color (first 2 weeks). The light is incredible for photography.

The Verdict
If you asked me to pick just one time? September 10 – October 5. The weather, the colors, the light, the (relative) lack of crowds — it’s the sweet spot.
But honestly? Xinjiang in any season is better than not going at all. Just pack for the conditions and adjust your expectations.
