When visibility changes, you must actively manage safety through pace, communication, and awareness of where everyone is. The best approach is to descend at a slower pace, give clear cues, use distance-based communication, and perform frequent position checks. Slowing down gives you and your student time to react to changing sightlines and terrain, reducing the chance of misreads or surprises. Clear cues leave little room for misinterpretation when you can’t rely on sight alone, and distance-based communication helps you maintain a safe following gap so you can still interpret each other’s actions even as contrast and depth fade. Frequent position checks keep you confident that you’re both where you’re supposed to be, allowing you to adjust immediately if visibility worsens or a turn or obstacle appears. Choices that push a rapid pace with few cues can quickly lead to lost contact or misjudged terrain when you can’t see well. Ignoring cues and waiting on student initiative removes the guidance that keeps everyone on a safe line, especially in uncertain visibility. Relying only on non-verbal cues can fail when sightlines are limited or attention is divided, so a mix of clear verbal and visual cues is more reliable.
