午前は快晴の槍ヶ岳。午後から岩稜は霧雨

As of 7:30 AM, Mt. Yari's summit is clear with a temperature of 10℃ and calm winds. The temperature difference from the 1500m base is approximately 9℃. With light winds throughout the day, the effective temperature will be close to the actual air temperature. For layering, wear a quick-drying base layer with a light mid-layer during activity, and carry a windproof and waterproof shell for breaks or potential afternoon weather changes.

The clear weather will persist through the morning, keeping the rocky ridges dry. However, light drizzle is expected to begin around noon, with precipitation probability rising to 76% by 3 PM. The chains and ladders on Hotsaki Peak will become wet in the afternoon, increasing the risk of slipping and falling. It is advisable to pass these hazardous sections in the morning. Crampons or microspikes are not necessary, but rain gear is essential.

The automated risk assessment indicates a rapid temperature drop of 6℃ during the forecast period. If you get wet from the afternoon drizzle and temperatures fall, the risk of hypothermia increases. Carry an extra thermal layer and wear rain gear promptly. While the risk of thunderstorms and strong winds is low, be prepared to turn back early if weather conditions deteriorate. Temperatures will drop to around 5℃ overnight, requiring sufficient cold weather protection even when staying in a mountain hut.
