Beijing, where it is located

In Beijing, the capital of China, located in the northeast of the country, 140 km (85 mi) away from the Bohai Sea Coast, the climate is continental, with cold but sunny winters, and hot, sultry, and rainy summers. Like many areas of China, the city is affected by the monsoon circulation: in winter, cold currents from the northwest prevail, while in summer, they are replaced by hot and humid currents of tropical origin. Spring and autumn are transitional periods.
Here are the average temperatures.

In winter, the average temperature is a few degrees below freezing (0 °C or 32 °F); sunshine is quite common, and a cold wind blows from the deserts of Mongolia. On colder periods, the temperature remains below freezing even during the day, and can drop to -15/-18 °C (0/5 °F) at night. Although the winter is a dry season, sometimes it can snow.
In winter, and especially in spring (March to May), the city can be affected by yellow dust, coming from the deserts of Mongolia and Central Asia, which forms a characteristic haze and brings breathing problems and eye irritation. On the other hand, when the wind is weak and the air is stagnant, the city is hit hard by smog. This situation occurs more easily in winter, while in summer, it goes better because the heat usually causes rising currents, in addition, it can rain.

In spring, the temperature increases rapidly, so much so that it often exceeds 20 °C (68 °F) already in April, and the average maximum of May, around 26 °C (79 °F), confirms the precocity of warm weather.

In June, it's already as hot as in the middle of summer, in fact, the maximum temperature in July and August does not increase any more. This happens because the summer monsoon arrives around mid-June, bringing rainfall, sometimes heavy, and high humidity. So, the summer in Beijing is hot, but especially muggy. July and August are the rainiest month. However, even in summer, there may be entire weeks without rain, and these periods are usually the hottest ones, with highs about 35 °C (95 °F), and with the perceived temperature exceeding 40 °C (104 °F) because of the humidity. In July 2015, even the real temperature reached 40 °C (104 °F). The monsoon is quite irregular, here as in the north-eastern part of China, so the rains may be more or less abundant depending on year.
To escape the summer heat, locals go to Beidaihe or generally along the coast of the Bohai Sea, where sea breezes temper the heat.

In autumn, the weather improves, rainfall decreases and becomes quite rare in October. By September, the humidity decreases and the temperature becomes pleasant, while in October, nights begin to be very cool.

To avoid both the cold of winter and the heat and the rains of summer, the best times to visit Beijing are spring and autumn, and in particular, from mid-April to mid-May and from mid-September to mid-October.
