Not only does inflowing air affect cave temperature, but it also affects cave humidity. The same study showed that humidity was lower whenever the cave inhaled. Natural cave humidity is probably about 95%-100%. Cold air is usually dry, and when it enters the cave environment and warms it becomes even drier. Some areas showed humidity as low as 60% on days when the cave inhaled. Humidity did not stabilize until the Temple was reached, over 2000 feet into the cave.
