The best times to visit Beijing are in spring and autumn, particularly in the months of April, May, September and October. In particular, autumn is considered to be the best season to visit Beijing as the skies are clear and the weather is very comfortable. The four seasons are very clear in Beijing with a temperate spring, rainy and hot summer, clear autumn, and a cold, snowy winter. The average temperature throughout the year is 11.8°C. The coldest month is January with an average temperature of -4.6°C and the hottest month is July with an average temperature of 26.1°C. Unfortunately, spring and autumn are shorter than summer and winter. Although winter is technically longer, that should not keep you from traveling to Beijing as indoor heating is widely available. Nevertheless, as the indoor / outdoor temperature difference is rather large, travelers should be prepared with warm clothing and a thick coat is recommended for the colder months of the year. In winter, off-season discounts are to be had as well.
