I am considering doing a piston soak this winter as I am a bit bored this time of year. Is it more effective to do in warm weather or does the temperature matter little? I'll do it when temps are generally above freezing.
Chemical reactions do usually happen faster when the temperature is higher. That said, I don't think it will matter enough in this case to really matter except for the comfort of your digits.

I mentioned before: one of the best engineers I ever worked with, one day told me " in general, most chemical reactions happen twice as fast for every 10 degree C ( 18 degree F ) increase of temperature."
Which also means that in general, for every decrease of 10 degree C ( 18 degree F ) chemical reactions happen half as fast.
If you're trying to dissolve stuck-on-grime in your dishpan, warm water works best. I imagine cleaning piston rings would be the same. You have a finite amount of time before the solvent slithers past the stuck rings, and said solvent doesn't have a viscosity that thickens noticeably with cold. So yeah I bet warm weather's better.
Don't let that stop you though, cabin fever is a thing to overcome.
