夏の霧雨と低温。濡れた足元に注意

The summit experiences light drizzle with a temperature of 7.6°C, feeling like 5.4°C. There is a 3.9°C difference from the base. With 93% humidity, the ground is wet and trails will be muddy. Despite being summer, these cool and wet conditions pose a significant risk of hypothermia. The summit area, known for its Unkai Terrace and gondola access, means rapid ascent, preventing the body from warming up before exposure to the cold. This is a stark contrast to the dry powder conditions of winter.

Full waterproof and breathable rain gear is essential for any activity. Wear a quick-drying base layer such as synthetic or merino wool, and a fleece mid-layer, adjusting layers frequently, especially during breaks. Waterproof trekking shoes are mandatory, and caution is advised for slippery, muddy terrain. While gusts up to 7.4m/s are not severe, wind chill on wet clothing will further lower the perceived temperature.

Drizzle will continue intermittently throughout the day, with heavier precipitation possible in the afternoon. Conditions are forecast to clear by evening, becoming partly cloudy, but temperatures will drop further, reaching 5.3°C by early morning. It is advisable to limit outdoor activities to short durations today, avoiding any prolonged exposure.
