日本海からの強風。稜線は体感氷点下

Mount Chokai presents clear skies today. While summit temperatures will rise to around 5 degrees Celsius during the day, gusts exceeding 18 meters per second are forecast for the morning. The wind chill will hover around 0 degrees Celsius. The long ridgeline routes, directly exposed to strong winds from the Sea of Japan, and the rocky areas around Shinsan, the highest peak, pose a risk of losing balance due to these gusts. Adequate wind protection is essential to prevent hypothermia during your ascent.

Ground conditions will be a mix of remaining snow patches and exposed rock depending on the elevation. Where snow remains, especially in shaded gullies, refreezing may occur, so carrying light crampons or microspikes is advisable. Expect wet and muddy sections due to snowmelt.

For layering, a wicking base layer, a fleece or light down mid-layer, and a windproof and waterproof shell jacket and pants are essential. Carry an additional insulated jacket for breaks or worsening conditions, and do not forget gloves and a hat.

Winds are expected to diminish slightly in the afternoon, but temperatures will drop to around 2 degrees Celsius by evening. If your activity extends into the late hours, ensure you have sufficient insulation layers. Visibility is excellent, but be mindful of energy depletion from the wind and plan your ascent accordingly.
