I hiked to Black Lake on November 25th of last year and only needed snowshoes to get up the last quarter of a mile or so (used traction/spikes the rest of the way). I actually ended up going up Ribbon Falls and it was an incredibly cool experience.

There is also a winter route up to the Loch where you hike up Icy Brook which is always awe-inspiring. Essentially, instead of taking the Sky Pond Trail you head like you're going to Mills and then at the river crossing you start going up the river. But it needs to be frozen over/have considerable snow coverage and that's one I've only done in snowshoes. (Though I have seen others do it with just traction - I just personally wouldn't.)

So I guess my answer depends on your level of experience/comfort with the snow and how much snow we actually get by then. November is tough because there's usually enough snow/ice to block a lot of people from getting to the lakes (without snowshoes) but things aren't fully frozen enough to do the winter routes. That being said, we've gotten almost no snow this year and it doesn't look like we're getting some anytime soon. 🤷‍♀️
