Best Time to Visit
High season marks the most popular times of the year for travel in China, due to the weather, holiday periods or other reasons. Therefore hotels, airlines and travel agencies are heavily booked, and prices are higher than at other times. The seasons are usually defined as follows: High season: April 1 to May 31, Sep 1 to Nov 15. Shoulder season: June 1 to Aug 31. Low season: Nov 16 to Mar 31. However, there may be some variations to these dates by different hotels, airlines or travel agencies in different regions. For example, high season in Tibet is from Apr. 1 to Oct 31 and the rest of the year is considered to be low season. Travelers should also be aware that the peak holiday periods: first 3 days in May, first week in October, Chinese Spring Festival (often takes place in late January or early February) are particularly busy. Prices and bookings will be even higher than usual. China Highlights Travel reserves the right to vary prices as a result of seasonal charges being imposed.
The best time to visit China depends on which places you wish to visit, what type of weather you enjoy. May, September and October are the peak tourist months at China's most popular destinations when the weather is comparatively comfortable, but prices are higher, and everywhere is more crowded. Prices drop a bit in the shoulder season, which runs from late March through April and from June through August. The low season arrives in late November, and continues through the winter to March, when there are fewer crowds and the prices are lower.
There's a lot of it, from tropical in the far south to sub-arctic in the far north! China's a big landmass, running from the Pacific to the Himalaya, with latitudes similar to the US. A trip through Beijing, Xi'an, Shanghai and Guilin would be like going from New York to Florida via Texas and Wisconsin. It's about 5,500 kilometers from the tropical south to the cooler north, and there can be as much as 40 °C (130 °F) difference between them. In winter the monsoon blows in from Siberia, bringing very cold, dry weather in the north, and weakening as it travels south, while in summer the monsoons bring warm wet weather in from the ocean, and summers can be very hot and humid in many areas. Spring and Autumn usually bring the best weather.
