I dont really see why low temperature and low humidity would have any negative effect on a cigars taste or burn.
I have smoked down to -5 degrees this winter and had no problems with taste or burn compared to taste or burn at summer temps in the 80's frequently, but with low humidity as Wyoming doesn't really get above 40% humidity at the most in every temperature and season, so I don't feel the weather here has much if any effects on my cigars, aside from high winds which we get often as the average elevation for all of Wyoming is at least 4500ft or more, so we always have some wind.
I'm able to avoid the burn issues wind seems to cause as we have a little glass shelter, exactly like you would find at a bus stop, to smoke in. Plus there's always the fully enclosed and attached to the facility, big smoking room on the opposite side of the facility from me, so i rarely smoke in there unless its pretty cold as it tends to be a bit warmer than the shelter by my room, likely from picking up a little bit of the facilities heat since its attached, but still 100% glass, so not at all insulated.
Is the burn at low temperatures your reasoning behind suggesting pics of the cigar burning, in my reviews?
The rest of my review obviously already covers tastes and burn too, so I've got the flavor thing covered at least
I could include temperature and humidity in my reviews if you feel it would be an improvement.
I friggin' LOVE cigars
