Cache only available 5 months of the year in General geocaching topics Posted October 24, 2010 "Oh, it's too wet" is not a valid reason, IMHO. We have caches in the Louisville area that are under 20 feet of water for some months. They're really only available for about 6 months out of the year, and for several of those months can only be reached by boat. They're behind a dam in the Ohio river. An example of only being available during certain times of year and one of my favorites is near the South Pole. It can only be accessed during the Summer, because it's dark the other 6 months and no one can get there.
