No real data, but I would expect December to be very slow, especially because everyone's vacation days expire at the same time (and disappear forever if you don't use them). Even now I'm starting to notice a lot more of my opponents on vacation than have been in the past.
I wonder if January is a big month for moves, then, with Vacation Flags dropped and chess players eager to get back to some games, or whether there is just that initial burst of activity and then back to normal.
I thought one possibility would be February as a high move-density month, cold outside for Northern Hemisphere, not much else to do.
