Yunnan covers a huge range of altitude and climate, so the best time to visit depends on where you are going. Kunming is famed for its spring-like weather, while the north is high and cold and the south is warm and humid. This guide breaks down the seasons and shows how they affect the main sights.
The overall pattern
The province has a dry season from roughly late autumn to spring and a wet season from about May or June to September or October. In the wet season, rain often falls in the afternoon and at night, with mornings often clear. The dry months bring sunshine, cold nights in the highlands and clear mountain views. Altitude changes everything, so a warm day in Kunming can be a freezing one in Shangri-La.
Spring (March to May)
Spring is one of the best times for most of the province. Kunming is mild, flowers bloom, Yuantong Temple's cherry trees are in blossom around late March and early April, and Dali and Lijiang have clear skies and green fields. The Third Month Fair in Dali is a spring highlight. The Yuanyang terraces are still flooded early in the season, though the mirror effect fades as planting begins. Rapeseed flowers colour fields in some southern areas in late winter and early spring.
Summer (June to August)
Summer is warm and green, with afternoon showers. Kunming is comfortable, while lower areas are hot and humid. It is a good time for Shangri-La's meadows and wildflowers, and for the Sani Torch Festival near the Stone Forest, which is held in the summer according to the lunar calendar. Tiger Leaping Gorge is dramatic but landslide risk rises, so check conditions. Jade Dragon Snow Mountain is often cloudy. Domestic tourism peaks in school holidays, so book early.
Autumn (September to November)
Autumn is excellent, with clear air, mild temperatures and golden light. Dali and Lijiang have good visibility, Shangri-La shows colour in the forests and meadows and the harvest brings gold to terraces and farmland. National holiday weeks in early October are very crowded, so travel just before or after if possible. The Dongchuan Red Land shows strong colours in many seasons, and late autumn is a popular time for photographers.
Winter (December to February)
Winter is dry and sunny in Kunming, Dali and Lijiang, with cold nights and often clear mountains. It is the best time for the flooded Yuanyang terraces and for gull watching at Dianchi Lake and Green Lake. Jiaozi Snow Mountain may have snow, and Shangri-La is cold but crisp, with fewer visitors and some closures. Bring warm layers, as heating in hotels and restaurants can be limited.
Festivals and holidays
The Chinese New Year period brings heavy travel and high prices, and many local businesses close for a few days. National Day week in early October is the busiest. Local festivals, such as the Torch Festival, the Third Month Fair and Naxi and Tibetan celebrations, add colour, but dates follow the lunar calendar and change each year, so check before you plan.
Sight-by-sight guide
Stone Forest: spring and autumn for comfort. Jiuxiang Cave: any dry day, or summer for coolness. Dianchi gulls: winter. Yuanyang terraces: December to April for water, summer for green. Dongchuan Red Land: autumn to spring for colour. Dali and Lijiang: spring and autumn, with winter sunny but cold. Jade Dragon Snow Mountain: autumn and winter for clear views. Tiger Leaping Gorge: spring and autumn for trekking. Shangri-La: late spring to autumn.
Packing for the season
Pack layers in every season, because mornings and evenings are cool at altitude. Bring a rain jacket in summer, warm clothing and gloves in winter, sunscreen and sunglasses all year, and sturdy shoes with grip. A small first aid kit and any medication are wise for remote areas.
If you can only choose one window
Late March to May and September to early November are the safest choices for a classic loop of Kunming, Dali, Lijiang and Shangri-La. For photographers who want terraces and mountains, winter is rewarding and quiet. Whatever the month, leave slack for weather.
Crowds and prices
The busiest periods are the Chinese New Year holiday, the early October National Day week and the summer school break, when trains, hotels and popular sights fill up and prices rise. Shoulder months such as late April, May, late September and early November offer pleasant weather with fewer crowds. If your dates are fixed, book key trains and tickets early and aim for early-morning visits to popular places.
