稜線は濃霧と体感低温。油断せず慎重に

Mount Haku's summit is currently under thin clouds with visibility below 1 kilometer, and the wind chill is a cold minus 1.3 degrees Celsius. There is a significant temperature difference of about 9 degrees Celsius between the summit and the base, meaning conditions will become harsher as you ascend. Although temperatures are expected to rise gradually during the day, the exposed ridges of Gozenmine and Onanjimine will maintain sub-zero wind chills due to the wind.

The ridges will frequently be enveloped in dense fog, causing poor visibility. Despite it being early June, there is a high probability of remaining snow patches and cornices on north-facing slopes and in gullies. Even on popular routes like the Sabo Shindo, extreme caution is necessary when traversing any remaining snowfields to prevent falls. Carrying microspikes is strongly recommended.

With 100 percent humidity, the risk of hypothermia increases if clothing becomes wet. It is crucial to wear waterproof-breathable outer layers over insulating mid-layers to maintain core body temperature. Hydrate frequently and consume energy-rich snacks during your ascent. Although the probability of precipitation increases in the evening, no actual rainfall is expected. Overnight, clear skies will bring temperatures close to freezing, so plan to complete your climb and descent during daylight hours.
