From New Scientist:
The viruses that cause colds spread faster in the winter because people spend more time inside, where they are closer together.

People close the windows in the winter so air contaminated by virus particles is not diluted by "fresh" air from the outdoors. This makes it easier for the viruses to spread.


Also from New Scientist:
We do tend to be indoors more often in poorly ventilated areas during the winter and this aids the airborne transmission of viruses. Similarly, ultraviolet will kill viruses and this may be another factor ...

And i finally found some data about the temperatures that viruses like. it's not cold and clammy -- it's the temperature inside your nose!
Rhinoviruses (from the Greek rhin, meaning “nose”) cause an estimated 30 to 35 percent of all adult colds, and are most active in early fall, spring, and summer. More than 110 distinct rhinovirus types have been identified. These agents grow best at temperatures of about 91 degrees Fahrenheit, the temperature inside the human nose. (emphasis added)
