終日霧雨と風。濡れと冷えに警戒せよ

Kiroro summit will experience persistent drizzle or light rain throughout the day. While temperatures range from 6 to 7 degrees Celsius, high humidity above 90% and wind will make it feel much colder, with a current observed wind chill of 2.8 degrees Celsius. Gusts could reach up to 14.9 m/s by midday, leading to a significant chill when wet. A notable temperature difference of 4.5 degrees Celsius exists between the summit and the base.

With no snow cover, the ground is entirely wet due to continuous precipitation. Areas like the "Rinkan Tree Run" are likely to be muddy, and there's a risk of encountering obstacles such as fallen trees from past heavy snowfalls, which may be difficult to spot in the 3.5 km visibility of the misty rain.

Although the absolute temperature isn't extremely low, the combination of rain and wind chill increases the risk of hypothermia as body heat is easily lost when wet. Essential layering includes a quick-drying synthetic or wool base layer, a thin fleece for the mid-layer, and a fully waterproof rain jacket and pants for the outer layer. Waterproof and breathable gloves and a hat are also crucial to prevent heat loss from getting wet. Exercise caution, especially on exposed ridgelines where the wind will feel stronger.
