Split, properly stacked and top-covered (if your climate is wet) I'd say you can get your wood down to 10-12% MC over the course of several years. It'd be hard to get it much lower seasoning naturally because of relative humidity, unless you kiln-dry it and store it in a low-humidity environment.

To be honest, I have never checked the moisture after 3 years but I can tell you we once had some checked with a professional meter. It was cherry, which usually is not too high in moisture. Several pieces were split before checking and they all were at checked at 8%. Yet I would call that extreme as I doubt you can get much wood that dry without a kiln. On the other hand, the moisture content can vary a lot between various types of wood so about all you could come up with is an average. Still, in 99% of the cases, if your wood was split and then stacked properly, it should be ideal for burning.
Unless you move to the desert, probably around ten percent. I live between a lake and the ocean and the best I've ever seen here is 12-14% and that was some 4 year old white oak that was not getting rained on. But its not like I was testing it every day either. It may have gone a little lower in the Summer when I was more concerned with keeping the lawn cut or how my tomatoes are doing. If you're painting outside you want the surface to be below 16% with a target of 8 to 12%. If you wait for 8% here you'll never get anything painted. Some guys will tell you below 20% is OK but I don't believe it. I don't paint for a living so I could be wrong or too conservative.
12-15% in my experience where I live. This is with ~10 year old c/s/s/ stuff which was split on the larger side.
1st, welcome to the Forums! 2nd, I live Right on the South Jersey shore area. Hot as HELL in July and August mostly and the wind is usually a constant, but it is humid here mostly. After 3 years, I'm down to 10% fairly easy. I'll give you a little insight, I C/S/S some Mullbery freshly cut down in November 2025, It's now August and I checked some of the stuff on top getting pounded by sun this past weekend and Im at about 16%. It's drying fast! I "do not" cover my wood and it is baking in the sun from sun up to sun down, and it is blowing through it all day. This is just my area and it depends on if your wood is exposed to good sun, get's lot of air movement and not wet constantly. Now, when my wood is over 2 years old, I do put it in my wood shed to keep it dry and ready for the next seasons/winters burn.
