高湿度で鎖場は滑りやすい。稜線は冷涼な風

Today on Ishizuchi-san, conditions start mostly clear in the morning but are expected to transition to cloudy by midday. Summit apparent temperatures will range from 4 to 7 degrees Celsius in the morning, gradually rising to around 8 degrees Celsius in the afternoon, which is cool for this time of year. There is approximately a 4-degree Celsius temperature difference between the summit and the base, meaning it will get colder as you ascend.

Given the current high humidity of 97%, despite no precipitation, rock formations in shaded areas and gullies are likely to be damp. Specifically, the chains on Ichino-kusari, Nino-kusari, and Sanno-kusari are anticipated to be wet and slippery. It is crucial to maintain three points of contact, not relying solely on the chains, and to carefully check your footing during ascent. If you feel uneasy, making the judgment to use the bypass routes is a wise decision.

Essential gear includes a quick-drying base layer, a mid-layer such as fleece, and a wind and waterproof outer shell. For breaks, an additional insulating layer like a lightweight down jacket is recommended to prevent hypothermia. Gloves and a hat should also be carried. While gusts are not expected to exceed 9.6 meters per second, which is not considered strong winds, you will feel the wind on exposed ridges, contributing to the cool conditions.

Cloudy skies will persist from afternoon into the evening, with temperatures gradually falling. Although the risk of lightning is low, be mindful of potential changes in visibility and aim to complete your ascent early. Hypothermia risk is manageable with appropriate layering.
