Beijing is a city with four distinct seasons. The best season to travel Beijing is late spring and autumn. But autumn is taken as the golden tourist season of the year since there is sometimes in the spring of recent years, a yellow wind. The climate in Beijing is of the continental type, with cold and dry winters, due to the Siberian air masses that move southward across the Mongolian Plateau. The summers are hot owing to warm and humid monsoon winds from the southeast bringing Beijing most of its annual precipitation. January is the coldest month and July is the warmest.
