穏やかな夏山歩き 昼頃の弱い霧雨に注意

Hakkoda summit experiences a mild, partly cloudy morning with temperatures at 14.6℃ and a gentle wind speed of 1.58m/s. The temperature difference from the base is 5℃. Temperatures are expected to rise to around 17℃ during the day, with light winds continuing. Trails are generally dry, but high humidity in the morning and a light drizzle around noon may create some wet or muddy sections. Particular caution is advised in wetland areas.

The apparent temperature will remain around 15℃ throughout the day. A quick-drying base layer, a thin fleece or synthetic jacket as a mid-layer, and a windproof and waterproof shell as an outer layer are recommended. Although gusts are mild, peaking at 8.5m/s, wear your shell during breaks to prevent heat loss. Rain gear, both jacket and pants, is essential. Crampons or microspikes are not necessary.

Today, the risk of thunderstorms is low, and there are no strong wind warnings. However, the risk of getting lost in fog in wetland areas always exists. While visibility is currently good at 6.3km, consider the possibility of temporary visibility reduction due to the drizzle around noon. Always maintain diligent self-positioning and route finding, especially on the wetland route from Oodake to Sukayu. Be mindful of volcanic gas around Jigokunuma.

The evening is expected to be mostly clear, but temperatures will drop to the low 13s. Nighttime activity is not recommended. While the risk of hypothermia during the day is low, manage your body temperature carefully, especially when sweating or during breaks.
