How long do you have to wait before you can climb on sandstone after it rains?
After rain, it is generally recommended to wait until sandstone has had enough time to dry thoroughly before climbing on it. The exact duration can vary depending on factors such as the intensity of the rain, temperature, humidity, and the specific characteristics of the sandstone in question. As a general guideline, it is often suggested to wait at least 24 to 48 hours after rain before climbing on sandstone. This allows sufficient time for the rock to dry out, minimizing the risk of damaging the rock or compromising its structural integrity. It's essential to prioritize the preservation and conservation of climbing areas, so it's best to check local guidelines or consult with local climbers who are familiar with the specific sandstone area you plan to climb on.
