夏山ハイク快適。緩斜面で長距離歩きを楽しむ

As of 7 AM, Sapporo Kokusai Ski Resort summit is 14.6°C and the base is 17.6°C under clear skies, showing a 3°C temperature difference between the two elevations. Winds are light at 0.76 m/s. Throughout the day, weather will transition from clear to cloudy, but precipitation probability remains 0% and winds will stay generally calm. The peak temperature is expected to reach the upper 19s near the summit around noon. There is no snow cover; ground conditions are dry with exposed rock.

For daytime activities, the apparent temperature will be close to the actual air temperature. Wear a moisture-wicking base layer, a light fleece or shirt as a mid-layer, and carry a wind shell or light jacket for an outer layer to adjust to changing temperatures. Although it will be partly cloudy in the afternoon, rain gear is not necessary. Crampons or microspikes are not required. As this can be a long hike, carry sufficient water and snacks, and manage your energy wisely.

An automatic risk assessment indicates a "rapid temperature drop" of 7°C is expected during the forecast period. This is particularly relevant if staying in the mountains from evening into night. While winds will pick up slightly to gusts of 6.6 m/s around 3 PM, this is not severe enough to impede hiking. Nighttime temperatures will drop to around 10°C, so carry an extra insulating layer and be prepared to turn back early if conditions warrant.
