Are you talking 10-20 degrees inside a house in a given 24 hour day?
Yep, or even 30 degrees in 24 hours. It can go from 60F, give or take 5 degees, when the heat is off at night, to 85F, give or take, when a fire gets lit (temporarily until the fire settles down. Our house is too bloody weather proofed). The upper end is usually more like 75, give or take, though.
In my bedroom it normally stays over 75 day and night, but is pretty stable temp-wise.
As I mentioned, for a short time I had been keeping my cigars on the window sill (well protected from any sun, as I said), where it stays below 70, but now it's getting colder at night and for that reason there is too much temp fluctuation there for my liking, and so I took them out of there. Now, I've been turning the heat down in my bedroom, sacrificing personal comfort for my cigars.
I know it seems ridiculous that I freeze my ass off at 70 degrees, but I have a chronic illness that makes me sensitive to cold, and am also 30 lbs underweight, so I have no fat and barely any meat on my bones. So, I put an extra blanket on my bed and have been dressing warmer. Maybe I can adjust. Or I can get a cooler and be comfortable.
Or I could freeze all my cigars, but that's a hassle when you only get one stick here, 5 there, and besides I'm afraid I'd screw it up.
If so that is a very large temperature swing. I would be concerned about that much or a change. The more stable the temp and RH for the cigars the better.
Oh, I know it.
I don't have many cigars, but for
me they represent either a substantial investment, or else they were gifted to me and represent the generosity of brothers. So I take good care of them, as difficult as that has been. One way or the other, I keep the temp and RH stable, even if that means I have to babysit them constantly.
Hope you feel better soon.
