I purchase my green firewood at the end of March first of April and it is just perfect for winter use. I request oak, but that is almost impossible to get all oak however my supplier gives as much oak as he has in his cutting splitting wood pile in line. I have had all the types that you have listed and haven't had a bit of a problem with them. If the wood was cut in April it should be more than fine for winter use and no you are not early as many have there wood now dumped in their driveway waiting to be stacked.
