Yup, when the climate gets damp it can be excruciating waiting for that leather to dry. Thats where that little forced air heater comes in handy, I've been using mine for many years to give my leather a little more help in getting dry. It still takes hours, but its both safer and slow enough not to damage the leather.
I cant get much further south than I am without being in the desert again, just a little north and I get into the tropics of the Houston area so yea I fully understand things not wanting to get dry. Winter around here is our wet season and it can be a lesson is patience, but that little heater has been a life saver. Mine is a Patton brand and is over ten years old and going strong as I only use the lowest heat setting in the winter, and just air in the summer. Sometimes just getting an air flow over your work helps a lot in getting things dried. More often than not we are dead still and muggy, not a good climate for drying leather.
Sometimes leather can look dry, and feel dry, but if it is cool to the touch then its not dry. The core can still be damp even though all evidence of dampness has gone from the surface. Leather is incredibly dense inside, the fibers are very compressed, so it takes a bit for all that moisture to leave the leather.
