The urban transportation of Xian has been developed rapidly in recent years. The second ring road, third ring road and freeway-ring around the city have all been completed and put into service. The city buses and suburban buses can bring you to every corner of the city. Also, to meet the development of the tourism industry, tourist special buses and sightseeing buses are now operating. Although traffic congestion happens now and then, it is much better than that of Beijing and Shanghai. The local government also does a lot to relieve the traffic pressure, including widening roads, building pedestrian overpasses and running inter-zone buses, etc.
Xi'an weather is mild with four distinct seasons - a warm but variable spring, a torrid and wet summer, a cool and rainy autumn and a dry and cold winter. The annual average temperature is 13.5°C (56.3°F). The city has a moderate rainfall rate caused by the frequent summer storms and a succession of overcast and rainy days in autumn.
March to May is usually warm and pleasant and is the best time of the year to pay a visit. Early autumn running through September and October is also a good time for a visit.
Brilliance of thousand years endows Xi'an with enchanting temperament. The continuous history of the ancient civilized capital has apparently resulted in its magnificent culture. Today's Xi'an is a world famous tourist city and an inexhaustible treasure house of cultural relics. Now, heads of state from many countries and people from all walks of life come to the city to broaden their knowledge of Chinese civilization.
