The problem with firewood that has gotten repeatedly wet then dry then wet & dry again is that the innermost area of the wood has really never had sufficient time to completely "cure" or dry so that the pores of the wood close up. It might also rot internally & or get what I call "punky" or soft--sort of like watermellon that dries out internally. Usually oak will handle a few wet & dry cycles without any damage if covered after a couple of these cycles. You will also probably find worms & other critters living in the wood that has been wet & dry more than once. I'm not familiar with other types of firewood other than oak because that is all that I sell. Hopefully some of the other guys in the north area of the US will help you out with this also. I am in Florida which is usually wet 9 months of the year & especially this year with 4 Hurricanes blowing through in the past two months, Bill Irvine
