夏空広がるアンヌプリ 穏やかな登山日和

Niseko Annupuri greets the morning with clear skies. The summit temperature is 11.3℃ with almost no wind, offering calm conditions. The temperature difference from the base is approximately 6℃. Visibility is excellent, providing clear views of the surrounding mountains from the Niseko United area.

Clear skies will persist throughout the day, with temperatures gradually rising until around 3 PM, expected to exceed 15℃ at the summit. Winds will remain light, averaging around 2 m/s. This makes for a comfortable day, even for ridge line access. The ground is snow-free and dry due to no precipitation. However, even on routes primarily on the northwest slope ski runs, caution is advised for damp areas and muddy sections in shaded spots or near streams.

The perceived temperature during activity will range from 11℃ to 13℃. A wicking base layer is essential, supplemented by a thin fleece or synthetic jacket as a mid-layer, and a windproof, waterproof shell as an outer layer. A significant temperature drop of 7℃ is forecast during the period. Therefore, carry an extra insulating layer to prepare for sudden changes during your activity, and be prepared to turn back early if conditions worsen. Crampons and microspikes are not required, but rain gear is a must.

Temperatures will begin to drop in the evening, cooling down to the 6℃ range overnight. Although the precipitation probability temporarily increases in the afternoon, no actual rainfall is forecast. However, mountain weather can change rapidly. While the chance of thunderstorms is not zero, it is advisable to plan an early start and descent.
