It gets around 4°-10° for about a week every winter, at least since I started around 8 winters ago. Sometimes more, but we don't have to deal with ice or snow very often. Maybe once or twice, some years not at all.

I use a balaclava.

I have several sets of gloves that I use depending on just how cold. You can actually layer gloves just like other clothes. I use some woven cloth gloves for liners, which my wife buys at Joanne's craft store for about a dollar each (no idea what craft that's for). I'll put some slightly too large Pearl Izumi over those and that's good at least into the 30's, or heavier generic winter gloves for colder temperatures.
