The optimum time to travel in Xi'an is from April to October. However, try to avoid the golden week of National Day (1 October to 7 October) holiday, when everyone in China seems to be traveling around.
The Spring Festival period in January or February should also be avoided since more and more families take trips rather than stay at home as in previous times. During the holiday weeks you can expect to have difficulty getting hotel reservations and ticket bookings. Traffic conditions usually worsen and prices are frequently much higher.
