I notice my shop is more humid than my bedroom where my paddle is stored. In my shop the paddles keep a slightly dark, "damp" look for a week, once in the house or bedroom they dry to a whitish haze within a day, I suspect they will vary a bit depending where they are used around the country. If I take mine back into the shop ir starts to look a bit damp again after a few days.

Once damp they seem a little sticky and a bit harder to use.
