China spans five climate zones — from subarctic Harbin to tropical Hainan — so the honest answer to "when should I go?" is it depends where. For a first trip covering the classics, two windows stand out: April–May and September–October, when most of the country is mild, dry and clear. Below, the year at a glance, then the regions that break the rule.
In this guide
1. The four seasons, quickly
- Spring (Mar–May) — warming, blossom, generally dry. Peak of the year by late April. Our top pick alongside autumn.
- Summer (Jun–Aug) — hot and humid, rainy in the south; high season for families and the far west/north (Xinjiang, Tibet, Inner Mongolia grasslands).
- Autumn (Sep–Nov) — crisp, clear, golden light. Arguably the best all-round window; Beijing is at its finest.
- Winter (Dec–Feb) — cold in the north, mild in the south. Fewest crowds, lowest prices, Harbin ice festival, misty southern landscapes.
2. Month-by-month at a glance
| Month | What it's like | Good for |
|---|---|---|
| Jan–Feb | Cold north, mild south. Chinese New Year travel peak. | Harbin ice & snow, warm south, low crowds (outside CNY) |
| Mar | Spring begins, still cool up north. | South & east, early blossoms, low season prices |
| Apr–May | Mild & dry nearly everywhere. Prime season. | First-time classics: Beijing, Xi'an, Shanghai, Guilin |
| Jun–Aug | Hot, humid, southern rains. School holidays. | Xinjiang, Tibet, grasslands, high-altitude cool |
| Sep–Oct | Clear, crisp, golden. Best all-round light. | Everywhere — especially Beijing & the Great Wall |
| Nov | Cooling, autumn colour lingers south. | Zhangjiajie, Yunnan, fewer crowds |
| Dec | Cold north, mild south. Low season. | City sightseeing without queues, snowscapes |
3. By region & city
- Beijing & the Great Wall — best in Sep–Oct (clear skies, comfortable walls); April is lovely too. Avoid peak summer haze and heat.
- Xi'an & Shanghai — spring and autumn; both are muggy in mid-summer.
- Guilin & Yangshuo — April–October for green karst and full rivers; misty year-round, gently warm.
- Zhangjiajie — spring and autumn for the clearest pillar views; sea-of-cloud mornings after rain.
- Chengdu & pandas — pleasant most of the year; pandas are active and playful in cooler months.
- Yunnan (Lijiang, Shangri-La) — high and mild; spring flowers or autumn clarity; winter is crisp and sunny.
- Xinjiang & Tibet — summer to early autumn, when high-altitude and desert regions are accessible and green.
- Harbin — deep winter (Jan) for the Ice & Snow Festival — bundle up for −20°C.

4. Holidays & crowds to plan around
Three periods send hundreds of millions of people travelling at once. Sites stay open but get very busy and prices spike:
- Chinese New Year (late Jan / Feb) — the biggest travel wave; book far ahead, expect some closures.
- Labour Day (first days of May) — a packed domestic long weekend.
- National Day / Golden Week (first week of October) — the busiest sightseeing week of the year.
Travel just before or after these and you keep the good weather while skipping the worst of the crowds — one of the easiest upgrades to any China trip.
