日中は穏やか。午後の風と夜間の冷え込みに備えよ

The summit area of Sapporo Kokusai Ski Resort experiences clear skies this morning, offering excellent conditions for hiking. Temperatures will be mild, with only about a 3-degree Celsius difference between the summit and the base throughout the day. However, winds are forecast to pick up significantly in the afternoon. By 3 PM, wind speeds are expected to exceed 5.05 m/s, with gusts reaching over 15.8 m/s, which will lower the perceived temperature considerably. Hikers should wear a quick-drying base layer, a light fleece mid-layer, and carry a windproof outer shell.

Ground conditions are entirely dry, and with zero snow depth, crampons or microspikes are not necessary. Nevertheless, a rapid temperature drop of up to 12 degrees Celsius is anticipated over the forecast period, as indicated by the automatic risk assessment. Temperatures will fall sharply after sunset, reaching around 5 degrees Celsius overnight. If your activity extends into the evening, you must carry an additional insulating layer to mitigate the risk of hypothermia.

Despite Sapporo Kokusai Ski Resort's proximity to the city, there is a distinct difference in weather conditions between the summit and the base. The shift from comfortable daytime temperatures to a sharp evening chill is pronounced. As the afternoon winds increase, the perceived temperature at the summit will drop, making it crucial to make early decisions about turning back and to plan your itinerary without overextending.
