Best Times to Visit Beijing
The best times to visit Beijing are from March to May and from September to October. These temperate seasons provide the best climate, not to mention colorful scenery. In contrast, summer brings sweltering heat, and winter ushers in cold temps and sometimes snow. While you should be mindful of the weather, you should also steer clear of national public holidays. Millions of domestic tourists flood Beijing's historic and sacred sites. The surge pushes room rates through the roof. (Note that Chinese workers will receive the two days following major holidays off work.)
Beijing can still experience some hot days in September, but the humidity has dissipated, making it more comfortable to explore the city streets. In the fall, overnight temperatures reach the 40s and 50s, so bring some light layers. Hotels post sub-peak rates during this short shoulder season.
Aside from the holidays, Beijing's winter is the low point for Beijing's tourism. Because of that, you can find below average room rates, and you may have some tourist sites all to yourself. However, you'll have to bundle up. Daytime temps will stay in the 30s and 40s, while evening temps will regularly dive below freezing.
Spring is a vibrant and comfortable time to visit Beijing. Temperatures quickly rise into the 50s, 60s, and 70s as trees burst into bloom. Hotel prices will steadily increase toward summer, so book early. Also, you might encounter dust storms. If you do, stay indoors and take the precautions recommended by your hotel.
Summer is the peak travel season for foreign tourists. Therefore, you'll likely encounter higher airfare costs and hotel prices. But you'll sweat more than the prices during the summer. Temperatures in the high 80s are accompanied by lofty humidity levels. Be sure to pack an umbrella as July and August are the city's rainiest months.
