残雪と岩稜が混在する稜線。足元に集中せよ

Mount Chokai's summit is mostly clear today. While temperatures are expected to rise to 6°C during the day, gusts reaching 14.9 m/s will make the felt temperature drop below freezing at times. Although the snow depth is reported as 0cm, given Chokai's characteristic of having snow patches persist well into autumn, expect hard-packed residual snow in shaded areas and gullies. Especially around the "Shinzan" area, exposed rocky terrain and snow patches will intermingle, becoming slippery due to daytime melting and nighttime refreezing. Be vigilant for the risk of rockfall from unstable rock masses around Shinzan, which can be exacerbated by rising temperatures.

Ground conditions are generally dry, but anticipate wet and muddy sections where snow is melting. Essential layering includes a moisture-wicking base layer, a mid-layer such as fleece or a light down jacket, and a windproof and waterproof outer shell. Gloves and a warm hat are also necessary. For traversing residual snow patches, carrying microspikes is strongly recommended, though crampons are not required.

The strong gusts from the Sea of Japan can cause instability on exposed ridges. Exercise caution, especially on the open ridge sections of routes like the "Hokodate Course" and "Yunodai Course," and reduce your pace as needed. To mitigate the risk of hypothermia, keep breaks short and consume water and energy foods frequently.

Conditions will shift to partly cloudy to cloudy in the evening, with temperatures dropping to around 2°C. If your activity extends into the night, more rigorous cold weather gear will be essential. Visibility remains excellent, but always pay close attention to changing weather conditions.
