hi! i m planning to visit hongkong from 10 oct to 15 oct 2012 what will b the weather during october

Hi, during that time, the average temperature could be about 22-23 C. In general, it will be cool then, with some pleasant sunshine. The typhoon season would have passed, so rain would happen a little.
You can take along both the short-sleeved shirt and long-sleeved shirt then.
