涼しい一日、足元は泥濘。イゾラ山頂は風に注意

Current conditions at Isola summit (990m) are cloudy with a temperature of 10.1°C, feeling like 7.7°C. The base at 463m is 14°C, showing a roughly 4°C difference. Light drizzle is forecast until around 9 AM, with trails expected to be wet and muddy. This is especially true in shaded and heavily treed areas, common in Rusutsu's terrain, where high humidity will make surfaces slippery.

The perceived temperature during the day could drop close to 0°C when gusts exceeding 10m/s occur. A quick-drying base layer, a mid-layer such as fleece, and waterproof, windproof outer shells are essential. Carry gloves and a hat, ready to wear immediately during breaks. Winds are expected to strengthen in the afternoon, with gusts over 12m/s forecast around noon. Exposed areas like the Isola summit will feel even colder, potentially impacting your activity.

While no significant alerts were detected by the automated risk assessment, the combination of low perceived temperatures and wet ground always presents a risk of hypothermia. If you get wet and are exposed to wind, your body temperature can drop rapidly. Maintain your physical condition with frequent short breaks and adequate hydration and nutrition. Precipitation chances decrease towards evening, but temperatures will gradually fall to around 7°C by night. Plan your day to finish your activities before sunset.
