谷川岳 霧から晴天へ。視界回復に期待

Currently, the summit of Mt. Tanigawa is thinly cloudy with visibility below 1km. Early morning hikers must be cautious of route loss due to dense fog. Particular care should be taken around Toma-no-Mimi and Oki-no-Mimi to prevent getting lost in poor visibility. There is a 7.3℃ temperature difference from the base, with the summit feeling like 10.9℃, requiring appropriate layering.

Throughout the day, conditions are expected to improve to mostly clear skies, with temperatures ranging from 12℃ to 14℃. Winds will be mild, with gusts up to about 5m/s, posing minimal impact on activity. No precipitation is forecasted, but high humidity means the ground is wet to partially muddy. Exposed rock ridges are present, but slippery sections are common, so careful footing is advised.

Layering should consist of a quick-drying base, a mid-layer such as a thin fleece, and a waterproof-breathable outer shell to adjust for varying temperatures. While active, it may feel warm, but during breaks, actively wear a mid-layer to prevent hypothermia. Rain gear is essential. Crampons or microspikes are not required today.

Although the forecast indicates stable weather through the afternoon, Mt. Tanigawa is known for its sudden weather changes. Always remain vigilant for shifts in conditions and continuously monitor visibility and temperature trends. There is a possibility of light drizzle in the evening, so early completion of activities is recommended.
