There are four seasons in Beijing, the capital of China—short windy spring, long hot summer, cool pleasant autumn and long cold winter. The hottest month is July and the coldest is January. September and October with the pleasant and cool weather are the best time to visit this city.
Spring
To visit this city in spring(from early April to the end of May), you need to bring lightweight（薄型的） clothing: long-sleeved shirts（长袖衬衫） or T-shirts, jackets and thin sweaters. It is warm, windy and dry but the temperature changes sharply between the day and the night. Dress warmly when going out at night.
Summer
In summer(from early June to mid-September), it is very hot with much rain. This calls for light clothes as the temperature in July and August ranges（变化） between $30°\mathrm{C}$ and $40°\mathrm{C}$. Short and heavy rainstorms may come suddenly in the afternoon on sunny days.
Autumn
Short but beautiful autumn(from mid-September to the end of October) is travellers’ all-time favourite. Autumn in this city enjoys comfortable temperature and a lot of sunshine. Long-sleeved shirts and thin coats are necessary for autumn. From late October, the temperature comes down sharply, so warm clothing is a
must.
Winter
This city has a cold, dry and long winter from early November to March in the next year. The cold days have no let-up（停止） despite（尽管） sunny days. The average temperature in December, January and February is below $0°\mathrm{C}$. Be sure to wear wool sweaters and thick coats in winter.
