What's the weather like in Hong Kong during the Spring Festival?

During the Spring Festival this week, the Hong Kong Observatory predicted that the temperature was between 12- 19 degrees Celsius, so it was not too cold. Just wear a shirt, sweater and coat. Of course, you should prepare a windbreaker and wear it sooner or later. Before you leave http://www.hko.gov.hk/contentc.htm., you'd better browse the website of the Observatory.
