Yeah I had a smoke last night and it was a balmy 35f and it definitely lasted way longer. I guess that all makes sense, to marketplace I go to score a heater I think...
My cutoff for sitting outside with a pipe and book is about 50 degrees. While I still enjoy it, I've noticed it doesn't taste as good as when it's a bit warmer. I don't know for sure why, but I suspect I'm puffing harder.
I don't notice cadence changes as much in the cold as i do when having "just one more bowl" while procrastinating work-related to-dos. When smoking under pressure, i learned to choose a larger bowl. Maybe that'll help in your case, too. :P
