霧雨の山頂は滑りやすい足元。慎重に

Current conditions at the summit (893m) are cloudy with a temperature of 11.4°C (feels like 10.9°C), while the base (324m) reports light drizzle at 14.3°C. Light drizzle is forecast to continue at the summit from 9 AM until around 6 PM, with temperatures ranging from 13.8°C to 16.1°C, peaking in the afternoon. Although precipitation is light, high humidity will persist. Ground conditions are expected to be wet to muddy due to the drizzle and lack of snow cover. Areas like the direct summit access via the Furano Ropeway and gentler slopes in the Furano Zone will be particularly slippery.

Expected daytime feels-like temperatures at the summit will range from approximately 13°C to 15°C, but the damp air and drizzle may make it feel cooler. A layering system including a wicking base layer, a light fleece or synthetic mid-layer, and a waterproof-breathable rain jacket (top and bottom) is essential. While hiking, you may feel warm, but carry extra insulation for breaks, windy periods, and the evening. Good grip hiking boots and trekking poles are recommended due to the slippery, muddy ground. Crampons or microspikes are not needed.

The automatic risk assessment highlights a significant temperature drop of 7°C over the forecast period, from an afternoon high of 16°C down to 6.5°C by early morning. Prepare for this rapid change by carrying an extra insulating layer. Early decision-making to turn back is crucial, especially if conditions deteriorate or if you plan to be out late. Maximum wind gusts of 8.8 m/s are not severe enough to cause Ropeway closures or pose significant wind hazards, but the combination of wet clothing and wind can increase the risk of hypothermia. Maintain vigilance against hypothermia, particularly if you are out during the evening. Hiking is feasible today, but be thoroughly prepared for wet conditions and the significant temperature decrease later in the day.
