It's been quieter I've noticed as well, and the more I think of it, the more I seem to remember it usually being quieter as Fall/Winter set in.
I love the "cold" of Argentina and enjoy going for walks in this weather, while everyone else from the people at the bus stop, the portero,
the guy that owns the verduleria, and my husband are all dressed as if a Nor'easter is inbound while I'm in shorts still.
