It depends on the RH in your house during the time. In the winter, the ambient RH tends to be very dry so it's good to check the RH inside your cooler every now and then, I'd say every two weeks or so.

I'm lucky in that even in the winter, the RH in my finished basement (where my coolerdors are) never gets below 50%. I haven't added water to my beads in over a year and a half.
