霧雨に濡れる山頂。視界不良と低温に注意

Sapporo Kokusai Ski Resort is expected to experience persistent drizzle throughout the day. There is a significant temperature difference between the summit and the base, with the summit experiencing harsher conditions.

As of 7:15 AM, the summit (1086m) reports drizzle, a temperature of 4.1°C, and a feels-like temperature of 1.2°C. Humidity is at 98%, and visibility is less than 1km, indicating dense fog. The base (625m) is 7.1°C with a feels-like temperature of 4.9°C, also under drizzle. The feels-like temperature at the summit is forecast to remain around 3-5°C throughout the day, with continuous drizzle. Given zero snow depth, ground conditions will be wet and muddy all day.

Extreme caution is advised due to persistent poor visibility, especially in the summit area. Sapporo Kokusai Ski Resort, despite being close to the city, presents a unique risk of significant weather differences between its summit and base. The approximately 460m elevation difference means consistently lower feels-like temperatures, with rain and wind quickly draining body heat. Essential layering includes a wicking base layer, an insulating mid-layer like fleece, and a waterproof-breathable shell jacket and pants. Waterproof hiking boots and gaiters are also recommended. Crampons or microspikes are not necessary.

The risk of hypothermia is high, with summit feels-like temperatures at 1.2°C and remaining around 5°C during the day, compounded by rain and high humidity. Avoid prolonged activity in wet clothing, take frequent breaks, and maintain body temperature with warm drinks. Gusts up to 11.1m/s are not severe but could pose a balance risk when combined with poor visibility. Precipitation is expected to cease after 6 PM, with conditions improving to partly cloudy and then cloudy, though temperatures will drop to 4-5°C overnight. Prioritize early starts and descents, avoiding unnecessary risks in these conditions.
