Best Time to Visit Beijing
Peak season: April to October
The peak season starts from April and ends in October. In this period, the mild temperature and climate is very suitable for travel. As a result, the city is filled with lots of travelers and is unavoidably crowded at some popular sights. The travel cost will also be a little higher since many scenic spots have peak season prices. Nevertheless, while this is the peak season it is still the best time to visit Beijing for the most beautiful scenery.
Slack season: November to March
The slack season for Beijing is from November to March when the weather is becoming colder and colder and there are fewer tourists. Accordingly, the airfare, hotels and scenic area tickets cost less. Beijing in January and February is cold with the temperature as low as -10 C, so it's very important for tourists to keep warm from winter chills. Nevertheless, you may enjoy the snowy landscape of the city and have a good time since it will be less crowded in most of the tourist spots.
Times to Avoid Travel
Try to avoid the two busiest travel peaks of the year – the Chinese New Year in January or February and the Chinese National Day Holiday from October 1 to 7. During these two 7-day holidays, there will be large crowds at tourist attractions and you can’t really enjoy yourself. The airfare and hotels might cost three times more than usual, and it is extremely hard to buy a train ticket during the Chinese New Year. It is also better to avoid some 3-day public holidays like the Qingming Festival in early April and the Dragon Boat Festival in June. If possible, try to avoid the summer vacation from July to August, where there will be a boom of student and family trips.
