Winter Availability for Boat Rides/River Cruise

I am booking a family trip to China for January that includes from 14 years old to 80 years old. There are three optional excursions that we are considering and would like to know if they operate in January and what the experience is in January. Is it too cold on the boat to enjoy the scenery outdoors? Is it foggy? Is there an indoor cabin where you can see the scenery from or do you need to be out on deck to see? etc....

These are the optional excursions where we would be "on the water":
Huangpu River Night Cruise (Shanghai)
Grand Canal Cruise (Suzhou)
West Lake boat ride (Hangzhou)
