高湿度の薄霧。姿見駅から山頂へは慎重な装備で

Asahidake is experiencing partly cloudy conditions today, with summit visibility below 1km. The temperature difference from the base is 2.4℃, with the summit at 11.1℃. Daytime highs are expected to reach 15.3℃, but humidity remains high at 96%, with periods of light drizzle anticipated. Although winds are light, high humidity and drizzle can make the air feel colder.

Visibility will be poor, especially on the route from Asahidake Ropeway Sugatami Station to the summit. Be particularly cautious around the fumarole area (Jigokudani), where volcanic gases can concentrate, exacerbating poor visibility and increasing the risk of falls or route errors. The ground is generally wet, and rocky sections will be slippery. Muddy areas are also expected in places.

The felt temperature will be in the low to mid-10s Celsius throughout the day. A quick-drying base layer, a mid-layer such as fleece, and a waterproof-breathable outer shell are essential. Carry full rain gear (jacket and pants). Crampons or microspikes are not required, but exercise extreme caution on slippery rocky sections. While the risk of lightning is low, high humidity and drizzle increase the risk of hypothermia if you get wet. Take frequent breaks, stay hydrated, and maintain core body temperature. Temperatures will drop further in the evening, and precipitation probability will increase, so an early return is recommended.
