濃霧と岩稜の濡れ。足元とルート確認を徹底せよ

Current conditions at Akadake summit show cloudy skies with a temperature of 9.7°C, feeling like 8.6°C, and a very high humidity of 99%. Visibility is less than 1km due to dense fog. While the forecast suggests clearing to partly sunny skies by midday, high humidity persists, and precipitation probability remains high throughout the day, indicating a continued risk of mist or light rain despite 0mm precipitation forecast. The temperature difference from the base is 8.3°C, making the summit area cool.

Ground conditions will be predominantly wet. With no snow cover and high humidity, expect wet and potentially slippery rock sections across the exposed ridge lines. Particular caution is advised on the Bunzaburo-one Ridge and Jizo-one Ridge, where wet chains and footholds increase the risk of a slip or fall. Maintain strict three-point contact in these technical sections.

For layering, wear a quick-drying base layer, an insulating mid-layer such as fleece, and a waterproof-breathable outer shell. Carry an additional lightweight insulating jacket for breaks or unexpected drops in temperature. Rain gear is essential. Crampons or microspikes are not required.

The primary risk today is route finding due to severe low visibility from dense fog. Navigators must constantly refer to maps, compass, and GPS. Although wind speeds are light, the high humidity means that getting wet can quickly lead to a drop in body temperature. While the risk of severe hypothermia is low with proper gear, avoid prolonged stops if wet. Thunderstorm risk is not high, but be alert for any rapid changes in cloud development, especially in the afternoon. Given the conditions, climbing is possible with extreme caution, particularly regarding navigation in fog and securing footing on wet, exposed rock.
