It’s usually pretty noticeable (make that smell-able) when the goldenrod flow is on. I like to extract the lighter honey before the goldenrod flow and put some supers back on just in case they pack in a lot of goldenrod. So the question kind of becomes, have you extracted yet?
If not, then I would probably do as Allen says and start pulling supers/frames that are capped and extracting. The warmer the weather, the easier the process is. You sure don’t have to wait until the golden rod flow is done. Any flow after you pull the supers, the bees will store for their winter usage.
Consolidate frames that are not capped into a single box, or whatever it takes. If you’re running mediums in wood hives in Ohio, I’m guessing you’re going to want to winter with 3 medium boxes. You’re going to want those upper 2 mediums to be filled with something (honey/syrup) within about a month.
