Searching for UGA and UF

The University of Georgia and University of Florida are, of course, rivals. UF, being bigger (and with large medical and engineering schools), gets a bit more attention, though UGA is much older. Both, it seems, are not searched for as much, at least according to the magic of Google Trends. See below. The blue is UGA, the red UF.

What are those cyclical blips up? Septembers. I can only assume that's a football effect, though I suppose it could also be a "back to school" effect. Impossible to tell from these data, but it's interesting how both schools blip up (or down) in the same months.
