May is one of the best times to visit China. Spring is in full bloom and temperatures are pleasant and mild. It is one of the most enjoyable months for travelling in China. The spring rains of central China are less frequent and humidity levels have usually decreased by this time of year. Days are usually sunny and evenings mild and warm.
During the day, short sleeved tops and a light cardigan will usually be enough. A light jacket for evenings is a good idea as the breeze can be cool, especially in northern China. If you are in central China, an umbrella is always a good idea as sudden spring showers still occur during this time of year.
If you do happen to be in China during May, it would be wise to stay clear of the May Day also known as the Labour Day holiday around the beginning of May. The May Day holiday used to be one week long but was shortened to just three days in 2008. This holiday also marks one of the peaks of domestic travel season causing hikes in hotel prices and transportation. If you wait until after the Labour Day celebrations, prices will decrease again and you’ll experience less congestion in terms of traffic and public transportation.
