Northeast China (Heilongjiang, Jilin, Liaoning)
Late spring in May is pleasantly warm and humid in downtown Dalian and coastal resorts, while Harbin stays brisk. Flowering meadows on the Jilin highlands and coastal beaches draw weekend crowds; it’s a popular time for Russians and Koreans to visit, so book ferries early. Insects begin to appear in lowlands-bring insect repellent-and roads to remote nature reserves improve after thaw.
North China Plain & Beijing (Beijing, Tianjin, Shaanxi fringe)
May becomes warm and pleasant across the North China Plain, with Xi’an and surrounding historic sites feeling balmy; it’s a popular month before the summer heat. Wildflowers and agricultural terraces on the Loess Plateau are attractive for photographers. Carry sunscreen and a hat for exposed ruins and the Great Wall, and book ahead for weekend hotel stays during the May Day holidays when crowds spike.
Inner Mongolia & the Grasslands
June brings warm, dry days with cool nights-this is prime season for grassland festivals, horseback treks and overnight yurts as Mongolia’s meadows are lush and wildflowers bloom. Thunderstorms can develop in afternoons, so plan open‑air activities for mornings. The region fills with domestic and international visitors for Naadam‑style events; reserve local accommodation and sun protection for long days outdoors.
Northwest China & Xinjiang (Urumqi, Turpan, Kashgar)
June in the desert oases and Turpan can already feel hot, with daytime temperatures rising steeply while mountain areas stay cool; humidity is extremely low. This is a busy time for cross‑regional rail and road travel, and the city bazaars hum with tourists. Sunscreen, a wide‑brim hat and plenty of water are essential for exploring the Flaming Mountains and ancient Silk Road ruins.
Tibetan Plateau (Tibet Autonomous Region, Lhasa, Everest approaches)
May brings pleasant daytime warmth in Lhasa and lower valleys, and the plateau starts to show green patches-this is a popular month for pilgrimages and high passes begin to open. Crowds increase steadily toward summer, and accommodations fill along main pilgrimage routes; book ahead for festival periods. Day-night temperature swings are large: pack layers and a good sleeping bag for overnight treks.
Southwest China (Sichuan Basin, Yunnan, Guizhou)
May becomes wet in many parts-monsoon rains increase in Yunnan’s south and Guizhou-yet the plateau and highland towns remain temperate and comfortable for trekking. This is wildflower season in alpine meadows and an excellent time for nature photography in the Shangri‑La area. Plan for occasional heavy showers and muddy tracks and bring quick‑dry clothing and a good rain jacket.
South China & Hainan (Guangdong, Guangxi, Hong Kong, Hainan)
May heats up and humidity rises, especially in Guangzhou and Guangxi; the seas warm around Hainan making beach activity inviting but crowded. Pre‑monsoon squalls increase; river tours and cave visits remain pleasant but expect sticky conditions in urban areas. Plan early‑morning outings for mountain parks and carry sunscreen, a hat and hydration for day trips.
