How is the weather for month of january in shijiazhuang?it is good time to travel?

According to the previous weather records, it would be very cold and there may be haze in that month. The average temp may reach 40 F in day time and 25 F or lower at night. It is best to prepare enough warm clothing. Considering all, it is not the ideal time to travel there. I'd recommend May to June. & Sep. to Oct. to you.
