霧雨が続き足元は滑りやすい。沢地形に注意

The Niseko Hirafu summit is under cloudy skies with a current temperature of 12°C, feeling like 11.1°C. The base area registers 18°C. Expect generally damp conditions throughout the day. Light drizzle is forecast to persist from morning, with a slight increase in precipitation probability in the afternoon. The ground will be wet to muddy, particularly in the tree run areas and around stream crossings, where footing will be slippery. Waterproof trekking shoes and complete rain gear are essential items for today's conditions.

Winds today will be light from the southeast to south, remaining relatively calm. However, a significant temperature drop of up to 7°C is forecast towards the evening and overnight. Continuing activities while wet from the drizzle significantly elevates the risk of hypothermia. Specific caution is advised when traversing stream areas near the Hirafu ski resort, as there is a potential for increased water levels and a heightened risk of slipping.

Due to the anticipated sharp decline in temperature, carrying an extra thermal layer is crucial. Any activities extending into the evening should be approached with extreme caution, and an early decision to turn back is recommended if conditions deteriorate or discomfort arises. The perceived temperature even during the day will hover in the low teens, so a layering system comprising a quick-drying base layer, a thin fleece or softshell, and a waterproof-breathable shell is highly recommended to manage the fluctuating temperatures and moisture.
