残雪の道、風が体感奪う。防寒と足元を固めよ

Asahidake summit area maintains a deep snowpack of 186cm, indicating late spring conditions. As of 7 AM, the summit temperature is 4.5°C, with a perceived temperature of 0.9°C. There is a -3.8°C temperature difference from the base. Although daytime temperatures will rise to 7.8°C, wind gusts reaching up to 14.9m/s will keep the perceived temperature low.

The route from Asahidake Ropeway Sugatami Station to the summit is still extensively covered in snow. As the snow softens with rising temperatures, be cautious of post-holing and muddy sections. While snowmelt progresses around the Fumarole Group (Jigokudani), vigilance for volcanic gas and hot springs remains crucial.

The perceived temperature will remain low throughout the day due to wind chill, so the risk of hypothermia is ever-present. Wear a quick-drying base layer, a fleece mid-layer, and a waterproof/windproof hard shell as an outer layer. Carrying rain gear is essential for the light drizzle forecasted for the afternoon. Chain spikes or light crampons and waterproof hiking boots are indispensable for navigating the remaining snowfields.

While no significant severe weather risks are detected, the potential for hypothermia due to wind chill will deplete your energy. Take frequent breaks to warm up and maintain body temperature with hot beverages. Light drizzle is expected from evening onwards, requiring vigilance for reduced visibility.
