霧雨で足元滑りやすいハイランド急斜面は特に注意

Mount Sapporo Teine summit will see cloudy conditions in the morning, transitioning to light drizzle around noon, and moderate drizzle in the afternoon. Daytime temperatures will range from 18°C to 22°C, but with a noticeable 3°C difference from the base, the summit will feel cooler. Winds will remain light throughout the day, posing minimal strong wind risk.

Due to the afternoon drizzle, the steep slopes of the Highland Zone and rocky sections will become wet and slippery. Particularly in the advanced courses, once an Olympic venue, unstable footing increases the risk of falls. The ground will shift from wet to muddy, making waterproof trekking shoes essential.

Although the apparent temperature is between 17°C and 22°C, getting wet from the drizzle will lower the perceived temperature. While the risk of hypothermia is low with proper gear, waterproof and breathable rainwear (jacket and pants) is mandatory. A quick-drying base layer and a light mid-layer are recommended. Thunderstorm risk is low, and crampons or microspikes are not needed.

Drizzle will continue into the evening, with temperatures around 17°C. The night will clear to cloudy skies, but temperatures will drop to around 16°C. If your activity extends into the night, additional warm layers will be necessary. Visibility remains good at over 20km, but may temporarily decrease during periods of drizzle.
