Wuxi is actually on the same latitude as Cairo but got a completely different climate. Winter could be quite tough here and I see, while Cairo got 18 degrees daytime in winter, that in Wuxi the temperature is often below 0 degrees celsius. It is also quite damp air here so warm and cold feels a lot more. My recommendations is that you bring a good long coat when you are going here. There is a couple of free services for weather in China and I am putting out some of them here.
