The four seasons are very clear in Beijing with a temperate spring, rainy summer, clear autumn, and a cold, snowy winter.
Beijing is very sandy, especially in spring. Sandstorms might occur. It’s good to have a mask inside your bag.
Summer is hot and humid and can go beyond 40ºC, though weather report never exceeds 38ºC (because factory workers don’t have to work in that temperature). However, if you go outdoor, you can feel the heat.
Lakes begin to freeze by late October. I was able to ski on the lake inside Peking University by Christmas. Beijing weather in winter is extremely cold and dry. You can wash your cloths in the hotel at late night and find them all dry the next morning. Please make sure to bring rich moisturizers for your skin.
Visiting Beijing in winter has to take extra care in the way you wear. Whenever I go to Beijing on business, I just need a shirt and a thick coat. Because Beijing has indoor heating everywhere, I had no chance to get cold. However if you are a tourist and spend most of your time outdoor, you need to be well prepared. I would suggest wearing in layers so you can shed some clothing with indoor heaters on.

While the average temperature for the year is 13ºC, Xian is quite pleasant to be visited year round. Take for granted that daily temperature difference is high with a historical figure of 28.1ºC. Always keep a warm jacket with you.
The coldest month is January. It might go below 0ºC however with little snow.
If you plan to climb the peaks around Guilin and Yangshuo, it could be dangerous after a downpour. Likewise when visiting caves. You might not be able to get on a Li River cruise because of the tide. Even if you can get on one, the Li River won’t be beautiful after flooding. Do pay attention to local weather reports and keep the weather in mind when planning your Guilin activities.
In summer, Guilin is very hot and humid. The average temperature in July is 28.3ºC. Winter can be quite cool.
Hong Kong Weather - General
Hong Kong weather is very hot and humid in summer. However Hong Kong is fitted with air conditioning everywhere. Once you are indoor, you are fine. As Hong Kong weather is never too severe in winter, we don’t have heaters on. You don’t have to deal with the huge temperature difference between indoor and outdoor, as if you were in Beijing.

Hong Kong Weather - Typhoons
Typhoon signals are ranked 1, 3, 8, 9 and 10. While 9 and 10 denote a direct hit, it rarely happens. Our last number 10 was in 1999 and the previous one was in 1983. But there is generally a couple of number 8’s annually.
Nevertheless, please have an umbrella with you while visiting Hong Kong in summer. It protects you from sun and rain. Winter is relatively dry, but never as dry as Beijing and Xian are.
