The rainy season varies by region. Southern China (Guangzhou, Guilin): April-September, heaviest in June. Yangtze Valley (Shanghai, Wuhan): June-July (plum rain season). Northern China (Beijing, Xi'an): July-August, short heavy downpours. Southwest (Yunnan, Sichuan): June-September. Tibet: July-August monsoon. Pack an umbrella and rain jacket during these months. Rain rarely lasts all day.

Typhoons affect southern and eastern China from July to October, peaking in August and September. Affected areas: Guangdong, Fujian, Zhejiang, Hainan, and occasionally Shanghai. Typhoons bring heavy rain and strong winds for 1-3 days. Flights and trains may be cancelled. Monitor weather alerts. Inland cities (Beijing, Xi'an, Chengdu) are rarely affected. Travel insurance with weather disruption coverage is recommended.

The Great Wall is spectacular year-round, but best in autumn (October) when foliage turns golden and red, skies are clear, and temperatures are comfortable (10-20C). Spring (April-May) offers green hills and wildflowers. Summer is hot and hazy. Winter (December-February) is cold but uncrowded, with snow creating dramatic scenery. Avoid October 1-7 (National Day) when the Wall is extremely crowded.

Northern China: Beijing averages -5C in January, drops to -15C at night. Harbin reaches -30C. Southern China: Shanghai 2-8C, Guangzhou 10-18C, Sanya 20-25C. Central heating is provided in northern China (north of the Qinling-Huaihe Line) from November 15 to March 15. Southern China has no central heating -- indoor temperatures can be as cold as outdoors. Pack warm layers for winter travel.

Summer (July-August) temperatures: Beijing 25-35C, Shanghai 28-35C, Guangzhou 28-35C, Wuhan and Chongqing can reach 40C. Humidity is high in eastern and southern China. The "Four Furnaces" (Wuhan, Nanjing, Chongqing, Xi'an) are notoriously hot. Northern and highland areas (Tibet, Qinghai, Inner Mongolia) are pleasant in summer (15-25C). Drink plenty of water, use sunscreen, and schedule sightseeing for morning and evening.

Spring (March-May): Layered clothing is key. March: jacket or light coat, long pants, sweater. April: light jacket, long-sleeve shirts. May: T-shirts with a light layer for evenings. Comfortable walking shoes are essential. Bring a light rain jacket for April-May showers. The temperature difference between morning and afternoon can be 10-15C. Pack a mix of short and long-sleeve items.

Summer (June-August): Light, breathable clothing (cotton or linen). T-shirts, shorts, skirts, sundresses. Sun protection: hat, sunglasses, sunscreen (SPF 30+). Comfortable walking shoes or sandals. Bring a light rain jacket or umbrella for afternoon showers. One light sweater or jacket for air-conditioned restaurants and trains (they can be very cold). Avoid heavy fabrics -- humidity is high.

Autumn (September-November): Similar to spring, layered clothing. September: T-shirts with light jacket. October: sweater and jacket, long pants. November: coat, warm layers. Comfortable walking shoes. October is the best month for weather -- clear skies, mild temperatures. Pack a mix of layers. Evening temperatures drop significantly from October onward. A light scarf is useful.

Winter (December-February): Northern China requires serious winter gear: down jacket, thermal underwear, warm hat, gloves, scarf, insulated boots. Beijing: -5 to 5C. Harbin: -20 to -30C (pack for Arctic conditions). Southern China: lighter coat, sweater, long pants. Shanghai: 2-10C, needs warm layers as buildings lack central heating. Bring a face mask for Beijing winter smog. Pack hand and foot warmers for Harbin.

Yes, in northern China and high-altitude areas. Beijing gets occasional snow (1-3 times per winter, usually light). Harbin and northeastern China have heavy snow from November to March. Northern Xinjiang, Tibet, and high mountains receive significant snowfall. Southern China (Shanghai, Guangzhou) rarely snows. The Harbin Ice and Snow Festival (January-February) is the best time to experience snow and ice sculptures.

Sandstorms (sha chen bao) blow in from the Gobi Desert, primarily affecting Beijing and northern China in spring (March-May). They reduce air quality and visibility. Sandstorms have decreased significantly in recent years due to China's tree-planting programs. If a sandstorm occurs, wear a mask, keep windows closed, and limit outdoor activities. Check AQI (Air Quality Index) apps for real-time data.

The plum rain season (mei yu) occurs in June-July along the Yangtze River valley (Shanghai, Hangzhou, Nanjing, Wuhan). It brings continuous drizzle and high humidity for 2-4 weeks. While not heavy rain, the persistent dampness can be uncomfortable. Pack extra socks, use dehumidifiers in hotel rooms, and plan indoor activities. The rain is warm and relatively gentle compared to typhoons.

Cherry blossoms bloom in late March to mid-April. Top spots: Wuhan University (mid-March), Beijing Yuyuantan Park (late March), Shanghai Gucun Park (late March), and Kunming (early March). The exact timing varies by year and weather. Plum blossoms bloom earlier (February-March) in Nanjing and Shanghai. Check local bloom forecasts. Weekends are extremely crowded at cherry blossom parks.

Autumn foliage peaks in October-November. Top spots: Great Wall at Mutianyu and Jinshanling (mid-October), Beijing temples (ginkgo trees in late October), Jiuzhaigou (October), Daocheng Yading (October), and Tachuan (Anhui, November). The red maple leaves on the Great Wall are particularly stunning. Plan photography trips for mid-October to early November. Check local foliage reports for exact timing.

UV levels can be very high, especially at altitude (Tibet, Yunnan, Sichuan) and in summer. Tibet's UV index regularly exceeds 11 (extreme) due to thin atmosphere at 3,600m+. Bring SPF 50+ sunscreen, a wide-brimmed hat, and UV-protective sunglasses. In cities, UV is moderate to high in summer. UV-protective clothing (long sleeves, umbrellas) is commonly used by Chinese people, especially women.

Altitude dramatically affects weather. Lhasa (3,650m) has strong sun, cold nights, and thin air -- summer daytime 20-25C, nighttime 5-10C. Shangri-La (3,200m) is similar. Jiuzhaigou (2,000-3,000m) has cool summers. Mount Emei's summit (3,099m) is 15C cooler than its base. Pack layers for high-altitude destinations. The temperature difference between sun and shade is significant. UV protection is essential.

Hong Kong has a subtropical climate. Spring (March-May): 18-27C, humid, foggy. Summer (June-August): 27-33C, very humid, typhoons possible. Autumn (September-November): 23-28C, best season -- clear and comfortable. Winter (December-February): 15-20C, mild. Pack light clothing most of the year; a light jacket for winter. Rain is common from May to September. Check typhoon warnings during summer.

Yes, China is seismically active, particularly in Sichuan, Yunnan, Tibet, and Xinjiang. Major earthquakes are rare but have occurred (2008 Sichuan earthquake). Modern buildings in major cities are built to seismic standards. If you feel an earthquake: drop, cover, and hold on. Avoid elevators. Follow hotel staff instructions. Register with your embassy's travel advisory service. Minor tremors are common in southwest China and usually harmless.

Elderly travelers should visit in spring (April-May) or autumn (October-November) when temperatures are mild (15-25C) and humidity is low. Avoid summer heat (June-August) in southern and central China. Avoid winter cold in northern China. Shanghai and Hong Kong in October are ideal. Choose flat, accessible destinations (Shanghai, Hong Kong, water towns). Avoid high-altitude destinations (Tibet, Jiuzhaigou) unless cleared by a doctor.

Air quality has improved significantly since 2015 but varies by season and city. Beijing: AQI 50-150 (moderate) in summer, 100-250 (unhealthy) in winter. Shanghai: generally better, AQI 40-100. Southern cities (Guangzhou, Shenzhen): best air quality, AQI 30-80. Check real-time AQI using the AirVisual app. Wear a mask (N95) when AQI exceeds 150. Winter air is worst due to coal heating in the north. Summer is generally cleaner.
