大雪渓は雪解け進む。踏み抜きに注意

Hakuba Peak is experiencing a clear and calm morning. While the base area is warm at 18.1°C, the summit is cooler at 6.2°C, feeling like 3.6°C. Temperatures at the summit are forecast to rise to 10.7°C during the day, with light winds throughout, indicating a generally favorable day for activity.

The current snow depth is 101cm. The Daisekkei (大雪渓) snowfield is undergoing rapid thaw. The rising daytime temperatures will further soften the snow surface. Particular caution is required on the Daisekkei due to the risk of slipping on the soft snow and post-holing. Light crampons are essential, and an ice axe should be carried and used proactively for careful ascent. Many rocky sections are exposed on the ridges.

As indicated by the automated risk assessment, summit temperatures are expected to drop by 8°C from evening to early morning. While base layers, a fleece or light down mid-layer, and a waterproof-breathable outer shell are sufficient for daytime activity, carry an additional thick mid-layer or down jacket for breaks and evening travel to mitigate the risk of hypothermia.

Although the risk of thunderstorms and strong winds is low, always carry a waterproof outer shell to be prepared for any sudden weather changes. An early start and descent before temperatures drop are advisable for safety.
